Mosquito Semen Fighting Dengue

Below article about fighting dengue with mosquito semen.

Arthropods is the provision of critical peaks rising Patogen animal people. A group of major vector is the mosquito that there are over 3,000 species. However, during the life cycle of mosquitoes feed on the blood of other animals - to create great opportunities for direct transfer manymicrobial species. From there, the bacteria / virus / worm infections can begin a new host, then, after another blood feed can transmit the pathogen to uninfected insects. This allows a certain lifestyle for the development of strategies to control pathogens to disrupt the vector species. If we remove or block vectors, we can prevent the spread of pathogens they carry.

Another group of mosquito-borne pathogens are the closely related - but distinct - dengue viruses (DENV). DENV is commonly responsible for a 'flu-like- illness' in humans but complications may include a potentially fatal hemorrhagic fever. The incidence is mainly constrained to tropical and sub-tropical areas although in recent decades it has spread to other areas where it may cause massive epidemics. The World Health Organisation states that, "Some 2.5 billion people – two fifths of the world's population – are now at risk from dengue. WHO currently estimates there may be 50 million dengue infections worldwide every year." There is currently no commercially licensed vaccine or antivirals available for the treatment of dengue leaving the only option to prevent transmission through control of mosquito populations.

The most important vector species is the predominantly urban species Aedes aegypti - control of which may aid DENV eradication. There are a number of potential strategies that could be employed to reduce the numbers of this species including chemical poisoning, genetic strategies and biological control. A major goal is therefore to inhibit mosquito reproduction and feeding behaviour yet this requires intimate knowledge of mosquito reproductive biology. Insects communicate via a number of chemical signals, one mode of communication is via the males ejaculate -what happens to be a convenient opportunity to control a females behaviour. A mated female is behaviourally very different to an unmated one and there is evidence suggesting that this change is initiated by the transfer of male-derived signaling proteins during mating. It may then prove to be useful to identify some of these molecules so as to possibly control mosquito behaviour ourselves.

What is so good about male semen?

Sirot et al recently report, using proteomic analysis, the identificantion of a number of proteins, termed seminal fluid proteins (Spfs) transferred from males (with labelled proteins) to females (non-labelled proteins) during mating. Of which some may be responsible for the male control over female post-reproductive behaviour; this they say, lays the groundwork for future studies investigating the molecular mechanisms behind how they work and their potential use in controlling vector populations. However, care must be taken in interpreting these results as this study does not directly look at the biological effects of these proteins and does not prove that they do have any effect on female behaviour.

Intracerebral Infection with Dengue

Today's about intracerebral infection with dengue -3 virus induces meningoencephalitis and behavioral changes that precede lethality in mice.

Dengue, one of the most important arboviral disease of humans, can cause severe systemic disease. Although dengue virus (Denvir) was seen as a virus, not Neurotropik, dengue infection has recently been linked with a number of neurological syndromes, including encephalitis.

In this paper, the changes evaluatedbehavioral and inflammatory parameters in C57BL / 6 mice infected with non-adapted dengue virus 3 (Denvir-3) genotype I.

Methods: C57BL / 6 mice received 4x10 * 3 pfu of Denvir-3 by ICP. We evaluate the cerebral microvessels of trade leukocytes using intravital microscopy, and evaluated kemokin and the profile of cytokines by ELISA at 3 and 6 days after infection (pi).

Next, determine myeloperoxidase activity and Mar immunity of the population, and the histopathological analysis and immunostaining for the virus in brain tissue.

Results: All animals developed signs of encephalitis and death by day 8 pi motor behavior and parameters for the reduction of muscle strength in 7 days pi

We observed leukocyte rolling and adhesion in the cerebral microcirculation of mice infected with three six days pi Infection was followed by a significant increase of IFN-gamma, TNF-alpha, CCL2, CCL5, CXCL1 and CXCL2.

The histological examination showed evidence of reactive gliosis, and meningoencephalitis. Increasing the number of neutrophils, CD4 + and CD8 + T detected in the brains of infected animals, especially in day 6 pi

Tues immunoreactive to anti-NS-3 on the brain down.

Conclusion: Intracerebral infection with non-adapted Denvir-3 caused encephalitis and behavioral changes before death in mice.

Prevention of Dengue with Homeopathy

It's about preventing dengue with homeopathy.

Dengue fever usually affects people living in tropical regions and it manifests with a sudden episode of high fever.
It has no mortality, have a self limiting course and the patient usually recovers within five to seven days.

The symptoms of Classical dengue fever ;

· Sudden onset with chills and high fever raised from 102 to 105 degree and continued about 3-5 days,
· Intense headache(retro-orbital),
· Severe muscle and backbone pain,
· Vomiting, tastelessness, weakness, dry tongue, constipation,
· Reddish eye, and oedoma on face.

The fever lasts for 5-7 days after which the recovery is usually complete. The chance of fatality is very low.


Dengue Hemorrhagic Fever :It is a more serious form of Dengue fever caused by infection of double Dengue virus and affects a small proportion of patients who are affected by dengue fever.

The clinical manifestations are:
· Fever-acute onset-continues-lasting for 2-7 days;
· Liver enlargement and tenderness. Pain feels at pressure on liver.
· Nausea and vomiting, abdomen pain,
· Severe pain on whole body especially in backbone and joints.
· Haemorrage- Bleeding under skin.-Bleeding from nose.-Gum bleeding.-Blood in vomiting.-Blood in stool

Homoeopathic management

Simple Dengue fever The most useful medicines for this type of dengue fever are Arsenic album, Bryonia, Eupatorium perfoliatum, Gelsemium, and Rhus toxicodendron

Dengue Haemorrhagic fever (DHF) can be treated with Crotalus horridus, Ferrum metallcum, Hamamelis, Ipecac, Lachesis and Secale-cor . .

These medicines can be safely used in every patient preferably 30 or 200 potency as per the indications and should be taken strictly under the supervision of qualified homeopathic doctors.

Regular monitoring of patients platelet count and leucocytes count is to be maintained

Preventive for Dengue in Homeopathy
Simple Dengue Fever (DF)

Eupatorium perfoliatum 200 can be taken twice daily for three days and subsequently at least two doses a week at the interval of three - four day till the epidemic persist for the prevention of dengue fever.

Dengue haemorrhagic fever (DHF)

Ipecac in 200 potency can be given twice a day for three days and two doses a week in all the patients those who have already suffered with the dengue fever and are prone for dengue haemorrhagic fever.

These medicines are safe without any side effects, but it is always better if these are used in consultation with the nearest qualified homoeopathic doctor.

Awareness About Dengue Infection

Today's talks about MCD to create awareness about dengue infection.

New Delhi, Feb 28 (PTI) The MCD will take measures to stop mosquito breeding and spread awareness about dengue infection.Instead of starting the work in May, domestic breeding checkers will begin their work from April 1 this year. This has been done keeping in mind the 6,229 people who contracted dengue from infected mosquitoes last year, an MCD official said."The number of people infected last year was gigantic.So many people got the infection because of the existence of a the dengue virus in a large population of aedes mosquitoes.Since there is a vertical transmission of the virus, transmission from mosquitoes to eggs, so there is a possibility that the family of the infected mosquitoes breeding this year is big too."That is why the DBC cum property tax checkers will start work from April 1 this year. They will spread awareness about the disease and check for mosquito breeding," an MCD official said.

Sandakan Records Highest Dengue Cases

These article about dengue cases in Sandakan, Sabah.

Sandakan recorded the highest number of dengue cases in the state last year due to the lack of awareness and knowledge about dengue prevention in the community, said Gum-Gum assemblyman Datuk Zakaria Hj Edris.

“The Ministry of Health through the Area Health Office and local hospitals promote health awareness as the main focus for early detection and control of dengue,” he said during the launching of Combi and ‘Jom Ganyang Aedes’ for Sandakan district level at Ulu Dusun Hall, yesterday.

He said, the Combi programme or Communication for Behavioural Change, aims to strengthen the community’s role in the prevention and control of infectious diseases.

“Infectious diseases are usually associated with human behaviour, including dengue fever,” he said.

The Jom Ganyang Aedes programme is a collaborative programme that encourages communities to take action in order to eliminate the breeding places of Aedes mosquitoes in or outside the home.

He said, the programme was to increase the community’s understanding towards the dangers and learn to eliminate the breeding of Aedes.

If one is found to be breeding the Aedes mosquitoes in the house or premises, one can be convicted under the Destruction of Disease-Bearing Insects Act 1975 which carries a minimum compound of RM500, and if one fails to pay within 14 days, a fine of RM10,000 can be charge, in default two years’ jail.

Dengue Cases mounts to 1841

Article about dengue cases.

Number of patients affected by viral haemorrhagic fever is increasing dramatically throughout the country as it is inserted in 1841, revealed by the Health Ministry here on Saturday.
According to reports, 16 people have died so far of dengue in the country, adding that patients were admitted to 3853 hospitals in different countries.

 

According to Ministry of health 105 Dengue cases are reported in Islamabad, 248 in the Punjab, 1382 in Sindh, whereas five cases in Azad Jammu and Kashmir.

Fighting Dengue by Using Lab Mosquitoes

Above about Malaysia to use lab mosquitoes for fighting dengue. Try product from the bottom of this blog under sponsor links.

Government authorities said Monday, Malaysia could be the first Asian country to use genetically modified mosquitoes for fighting the rise in dengue fever.

The programmed will see the release of genetically engineered male mosquitoes into the wild. The insects in the study have been engineered so that their offspring quickly die, which will help curb the increasing mosquito population, in a technique researchers hope could eventually eradicate the dengue mosquito altogether.

Laboratory test trials have made the Malaysian scientists optimistic.

The female of the Aedes aegypti mosquito that is quite common in Asia and Latin America is responsible for spreading dengue fever, whose symptoms include high fever, joint pains and nausea. There is no known cure or vaccine for the fever, which can lead to internal bleeding, circulatory shut-down, liver enlargement and even death in severe cases.

Efforts urging Malaysians to keep neighborhoods clean and destroy stagnant sources of water that are potential breeding grounds for mosquitoes, have failed and more innovation ways are needed for fighting dengue.

According to Health Ministry statistics, between January and early October, the number of dengue related deaths in Malaysia reached a total of 117, a 65% increase from last year. Overall, dengue infections increased 17% from last year to over 37,000 cases.

Lim Chua Leng, a Health Ministry official said, in the first experiment of its kind in Asia, Malaysian authorities plan to release between 2,000 and 3,000 genetically modified mosquitoes in two areas, after Cabinet approval has been received.

However, environmentalists are concerned the GM mosquito could fail to prevent dengue and also have unintended consequences.

Critics say the larvae will only die if their environment is free of tetracycline, an antibiotic commonly used for medical and veterinary purposes.

79 More Dengue Cases

Article about dengue cases in New Delhi.

The national capital reported 79 more dengue cases Tuesday, taking the total number of people affected by the mosquito-borne disease to 4,244, an official of the Municipal Corporation of Delhi (MCD) said.

Rohini zone in the capital is the worst affected area with 524 cases, followed by South and Civil Lines Zones with as many as 519 cases, the official said.

Seven people have died of the disease this year.

Meanwhile, a total of 21 chikungunya cases were reported from Delhi this year. There were no chikungunya cases last year, the official added.

Dengue still prevalent in Karachi

Article about dengue fever in Karachi. Read, click and try product from the bottom of this blog under sponsor links. ^_^

Health facilities are yielding no fruit in the metropolis as dozens of patients suspected with dengue fever are being reported in different clinics and OPD sections of various hospitals.

Health experts have warned citizens to strictly take preventive measures especially against the dengue fever, which can be transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses.

In-charge Provincial Dengue Surveillance Cell Dr Shakil Malik told TheNation that from January 1, 2010 to date, as many as 1758 dengue suspected patients are reported in the whole province, out of which 852 are found positive.

He said, “In the megalopolis, more than 700 suspected cases were been reported during the same time period, which shows the level of prevalence of the disease in the city.

Fortunately, the disease has claimed lives of only five patients this year. More than 70 patients are admitted in various public and private health facilities, including Civil Hospital Karachi, Abbasi Shaheed Hospital, Aga Khan Hospital, Anklesaria Hospital, Ziauddin Hospital, Jinnah Postgraduate Medical Center Hospital, Qatar Hospital, Sindh Government Hospital Saudaabad, LNH, NIBD, Karachi Adventist, Kutyna Memon Hospital, Fatima Bai Hospital, Patel General Hospital, OMI Hospital, Holy Family Hospital, OT Hospital etc.”

A renowned expert in mosquito species, Prof Dr Jamil Hasan Kazmi of Karachi University, while talking to TheNation on Sunday, said that the torrential rains have created new breeding points in shape of pools. He said that the temperature between 22 to 30 degree centigrade helps in the breeding of mosquitoes.

Talking about the global burden of dengue, he said, “The incidence of dengue has grown dramatically around the world in recent decades. Some 2.5 billion people, two fifths of the world’s population, are now at the risk from dengue. According to WHO’s fresh estimates, there may be 50 million dengue infections worldwide every year. In 2007 alone, there were more than 890000 reported cases of dengue in the Americas, of which 26000 cases were DHF.

Dengue Cases Reported

Above news about dengue cases.

Has the region finally begun to witness an onslaught of suspected dengue cases post the monsoon season?
While as many as 45 suspected cases of dengue have already been reported in the past one and a half months in the region, the fact that the cases have been pouring from almost all parts of the east UP region has kept the district health administration in a state of alertness.

"Cases have been reported from different parts of east UP region including districts like Mau, Azamgarh, Ballia, Ghazipur, Chandauli, Bhadohi, Mirzapur and Sonebhadra and the chief medical officers of the district have been already informed," district malaria officer (DMO) MA Khan informed TOI on Friday. "Out of these suspected cases, as many as nine cases have been reported from Varanasi district and most of the patients have recovered from their illness with no causalities reported so far," he said.

It may be mentioned here that the district has not reported any confirmed case of dengue fever in the past three years. Six confirmed cases were reported in 2006. As per reports of the DMO office, which is also the nodal office for control of vector-borne diseases in the region, even the confirmed cases reported in 2006 were of persons who had returned from New Delhi during the festive season.
"The suspected dengue cases reported from the region also bear resemblance to the cases in 2006, as most of them have been reported in people who have returned to the city from New Delhi in the past couple of months," said the DMO. "The situation is completely under control and every effort has been initiated to curb such cases," he added.

As per superintendent-in-charge, SPG divisional hospital, DB Singh, six beds for suspected dengue patients have been already reserved and the number can be increased with provision of make-shift beds in other wards if such a situation occurs. "All precautions are being taken to keep the dengue ward clean for optimal use of patients," he added.

It is also worth mentioning that beside the SPG hospital, SSL hospital, BHU, and DDU district hospital in the city are also equipped with separate dengue wards, each having the capacity of six beds. In addition, the district health administration has also made the provision of dengue kit in district hospital for confirming the cases of dengue fever, whereas BHU has its own set up with all the diagnostic and pathological testing facilities for confirming such cases.

Meanwhile, the district health administration, in support with Varanasi Nagar Nigam, has also initiated anti-dengue measures, including destruction of potential sources of breeding of mosquitoes. As per reports of VNN, the fogging drive has been already initiated on the prominent roads and residential colonies while health officials are also likely to start changing of water in the coolers, flower pots and water tanks to stop their growth.

Dengue Fever Spreads in Pakistan

Above news about dengue.

25 patients with dengue fever were admitted to Civil Hospital in Karachi, Pakistan Wednesday evening, as the mounting number of infected patients in the country grows.
696 people have been infected by the deadly disease since August 2010, according to data from Dengue Surveillance Cell Sindh (DSCS).
Fears mount that the problem may get worse as various areas in the country's Interior Sindh region are hard hit by the virus.
Dengue fever is an infectious tropics-based disease transmitted though mosquitoes; those infected develop a rash and experience pains in their joints and head.

Spread in Asia

Here's about dengue fever spreading in Asia.

Dengue fever, a mosquito-borne disease with no known treatment, is spreading in Asia, with cases in India at a 20-year high as the country hosts the Commonwealth Games.

The World Health Organisation (WHO) has warned that 2.5 billion people are at risk from one of the world's fastest-emerging infections, which has "grown dramatically in recent decades."

Officials at the WHO say Asia, home to 70 percent of the at-risk population, has seen a rise in dengue mainly because of higher temperatures due to climate change, rising populations and greater international travel.

The organisation says "a rapid rise in urban mosquito populations" is also bringing ever greater numbers of people into contact with the virus.

According to data collected by the UN body, the highest number of reported cases in Asia this year to August are in Indonesia (80,065) followed by Thailand (57,948) and Sri Lanka (27,142).

Dengue, transmitted to humans by the female Aedes mosquitoes, causes a severe flu-like illness for most victims that lasts about a week. There are four strains, one of which is a potentially lethal haemorrhagic type.

"The disease has spread fast. Dengue is appearing in new areas," said Yogesh Choudhri, an expert at the WHO on the Asia region, who said the disease had crossed new international borders and spread within countries.

It was found in the Himalayan countries of Bhutan and Nepal for the first time in 2004, and is endemic in most of Southeast and South Asia as well as Indonesia and East Timor.

In India, government hospitals in New Delhi are overflowing with dengue victims as the city hosts 7,000 foreign athletes and officials for the Commonwealth Games, which finish next Thursday.

A.C. Dhariwal, director of India's National Vector-Borne Disease Control Programme, told AFP that cases in India were at a 20-year high with 50 people dead and 12,000 reported infections.

The number of actual infections is likely to be far higher.

He blamed the delayed construction work for the Commonwealth Games for part of the problem in New Delhi, where monsoon rains have been at their strongest in years.

"Delays in Games construction and urban improvement projects are to blame for the severe dengue outbreak since mounds of rubble and puddles are strewn across the city," he said.

Last week an official with the Indian lawn bowls squad contracted dengue, the first person associated with the Games to to do so.

There is no known treatment for dengue, but several preventative steps can be taken.

The most important is to ensure there is no standing water near residential areas where mosquitoes breed.

Spraying insecticide, an approach taken by many city authorities, can also help, as does applying mosquito repellent and wearing long sleeves and trousers.

In Thailand, the government is worried about a South Korean-inspired fashion craze for black leggings which could be putting teenagers at risk.

"I'm worried about how people dress, especially teenagers," said Deputy Public Health Minister Phansiri Kulanartsiri, noting that the mosquitoes which transmit the disease are attracted by dark colours.

"The mosquitoes can bite through the leggings' thin fabric, so those who wear them are at greater risk of being infected with dengue."

In Sri Lanka, authorities have introduced heavy fines for people with standing water in their homes, and troops have been deployed to clean up public places.

Malaysia has reported a 53-percent rise in dengue-related deaths this year, but backed away from a controversial trial of releasing genetically modified mosquitoes to wipe out the disease.

In the first experiment of its kind in Asia, 2,000-3,000 modified male Aedes aegypti mosquitoes were to have been released in two Malaysian states in October or November.

Dengue Fever Return

Here’s info about dengue fever.

When the rains come, unless the fee we received from the pleu but it will cause many diseases such as foot Hong Kong, cold and dengue fever is a deadly disease and come again and again every year.
Dengue fever can occur throughout the year, but dispersed in the rainy season during May September. When the mosquito bites and dengue virus in the blood, bacteria will grow in the membrane of the stomach and spread to glands lenfatik the mosquito is ready to spread out to people who have mordu.
Virus causes dengue fever. Most virtual germs cause dengue, which has four types and the common house mosquito is a carrier of disease germs. the virus can live in the mosquito life. period for mosquitoes feed during the day, but at this researchers found steps mosquito behavior is changing food until 23:00.

We found all age of people can have a Dengue fever but most found in children age between 5-10 years. At the first period after bitten by mosquitoes, the patients will have a high fever 3-7 days and the symptoms is serious or not depend on each patient. Most patients will have high temperature, red face, stomachache, boring food, pain throughout body. Some patients have blood-spot on their skin. Most have no cold. The dangerous thing of Dengue fever is the patient or closed person will not know that they have a Dengue fever until they are in crisis and have bleeding in some part of body especially nosebleed, blood-spot on the skin, vomit, thirsty all the time. Please take the patient to see doctor immediately so doctor can cure in time.

Now Bangkok Hospital Pattaya can check Dengue germ by PCR method and the new updated method by Dengue NS1 Antigen. Both methods will present the result quickly and correctly within 24 hours so it’s a one way that can help to reduce risk of the death from Dengue fever.

PCR

- Know the result within 24 hrs.                        

- Expensive                                                                   

- Know the kind of Dengue germ                 

Dengue NS1 Antigen

-  Know the result within 24 hrs.

-  Cheaper

-  Unknown the kind of Dengue Germ (each kind has violenceAnd treatment differently)

Most of the time, we heard people died cause of dengue fever. So preventive and protective people you care by eradicate and frustrate culture area of the mosquitoes larvae by closing the cover of water-ware, check water in vase and change water every week to prevent mosquitoes lay its egg because it like to culture in clean-no movement water. And the patient should take care yourself and don’t let mosquitoes bite within the first 5 days of having this disease because virus is still in the blood and can spread to another person.

More than 50% drop in dengue cases

Here’s about dengue cases.

Dengue fever cases this year have more than halved compared to the first six months of 2009, local media reported on Wednesday, citing officials of Health Ministry.

However, health officials warn that more dengue infections are likely during the forthcoming rainy season, which is arriving late.

Seven people died in the first five and a half months of this year, the same toll as last year, but reported infections have decreased in the same period from 2,431 to 1,111, the ministry's dengue control program director Ngan Chantha was quoted by the Cambodia Daily as saying.

"The number has decreased, but we are calling on people to remain careful with the breeding of mosquitoes during the rainy season," Chantha said.

"From the 21st to 22nd week, the jump in cases is quite high," Chantha said, noting there were 242 cases in week 22. "We should be vigilant because July is a highly vulnerable month."

The decrease in dengue fever cases is due to the delayed rainy season, increased public awareness and health care system improvements, said Hai Ra, head of dengue control at Kompong Cham provincial health department.

In the first 21 weeks of this year there were 122 reported cases of dengue with two deaths in Kompong Cham, down from 315 cases with three deaths during the same period last year, Hai Ra was quoted as saying.

Kompong Cham is the second-most affected province after Phnom Penh, followed by kandal and Siem Reap.

What is Dengue Fever

Let’s talk about dengue fever.

“Dengue is the most common vector-borne viral disease in the world, causing an estimated 50–100 million infections and 25,000 deaths each year (1). During 1946–1980, no cases of dengue acquired in the continental United States were reported. Since 1980, a few locally acquired U.S. cases have been confirmed along the Texas-Mexico border, temporally associated with large outbreaks in neighboring Mexican cities (2–4). On September 1, 2009, a New York physician notified the Monroe County (Florida) Health Department (MCHD) and the Florida Department of Health (FDOH) of a suspected dengue case in a New York state resident whose only recent travel was to Key West, Florida. CDC confirmed the diagnosis, and a press release was issued to notify the public and Key West physicians of the potential risk for locally acquired dengue infections. In the next 2 weeks, two dengue infections in Key West residents without recent travel were reported and confirmed. Subsequently, enhanced and active surveillance identified 24 more Key West cases during 2009. On April 13, 2010, another Key West dengue case was reported to FDOH, bringing the total to 28.”

Symptoms of dengue include:

• fever
• severe headache
• pain behind the eyes
• joint and muscle pain
• rash
• nausea/vomiting
• hemorrhagic (bleeding) manifestations

Usually dengue fever causes a mild illness, but it can be severe and lead to dengue hemorrhagic fever (DHF), which can be fatal if not treated. People who have had dengue fever before are more at risk of getting DHF.

Dengue claims the student life

Above about dengue.

“The untimely death of my son was due to the lack of proper medical care at the hospital” charged a father of three children S. P. Wimalasena of Kawdana, Dehiwala.

He was making a statement regarding the death of 17-year-old S. P. Isuru Prabath, a year 12 student of Lalith Athulathmudali College, Mount Lavinia, suspected of Dengue.

Commenting further Wimalasena said that on May 31 his son Isuru Prabath developed vomiting, high fever and was removed to a private medical institute and later transferred to the national hospital Colombo on their advice.

Despite daily blood tests, no improvement was visible and on June 3, morning my son complained of breathing difficulty and shouted in pain. The Ward doctor in charge tried in vain to avail the services of a qualified doctor. In the afternoon my son was transferred to the ICU where he died, no post mortem was even held, the father complained.

K. B. Fernando (70) grandmother of Isuru Prabath in her evidence said the deceased was the only grand-son who was studying for the GCE Adv. Level before the untimely death.

US strikes by dengue fever

Here about dengue fever in US

Dengue fever has returned to the U.S. in the Florida Keys, after a 65.

The mosquito-borne virus has been identified in 28 people from Key West by the US Centers for Disease Control. The CDC announced the findings last week in its Morbidity and Mortality Weekly Report.

"We don't know for sure that this hasn't happened before without being noticed," says Christopher Gregory of the CDC's dengue branch in San Juan, Puerto Rico. "It could be the tip of the iceberg."

Most cases resolve after flu-like symptoms, says Gregory. He says the best precaution is to empty standing water from potential mosquito breeding grounds, such as birdbaths.

Gregory says the blame for this dramatic rise could lie with increased travel between the US and South and Central America and the Caribbean - areas which have seen nearly 5 million cases of dengue fever from 2000 to 2007. Infected mosquitoes have also been moving northwards, thanks to global warming.

Dan Epstein of the Pan American Health Organization in Washington DC is worried that these two factors could lead to outbreaks of dengue haemorrhagic fever, the most severe and lethal form of the disease, which is present in South America.

Gregory is more concerned about the potential spread of chikungunya, an incurable mosquito-borne virus, that causes crippling arthritis-like symptoms. It's only a matter of time before it reaches the US, he says.

Mosquito traps for Haiti

Here about dengue fever.

Even before the January 12, 2010 earthquake, Haiti, reported the highest incidence of the tropical world. After the devastation of the infrastructure capital of Haiti, from tropical threat has grown considerably as a result of lack of potable water for the city and the urgent need that people have to store supplies what little they can put into his hands.
In the best case, it is almost impossible to stand in line behind all efforts to prevent dengue mosquito to water tanks kept in and around the home, household, much less in the current circumstances, where the priority is the survival rate is open.
ProVector LLC has taken note of and the companies agreed to send his 1500 traps Haiti and several hundred more people in the Dominican Republic on the border with Haiti. The company hopes to design the program ProVector results (PVCP) where bouquets of flowers donated Provector Children of Nations, International (COTN) set Cotton, DR.
Approximately 200 traps set Provector, one inside the house and other buildings of cotton, which is only one of the poorest malaria and Dengue-supported trips to visit COTN DR. Of cotton men were obvious differences in mosquito infestations, where the trap was set against all the opposition parties. It was shown that the pesticide, Bacillus thuringiensis, in the center of the flower was part of the task to attract mosquitoes, and the destruction of the destination premises. Flower Provector would offer protection for the family 24 hours a day.
Hurricane season is not far away. The rain is coming and people of Haiti is probably still far fewer homeless shelter. Water is a scarce and storage containers, all open for dengue mosquito join all the temporary structures. Mosquitoes breed with joyful abandon. Infection will increase and the already strained health services, Haiti is struggling to cope.

Facts about dengue and yellow fever

Above about dengue and yellow fever.

Dengue is an important human viral disease transmitted by insects. Although nearly half the world's population is at risk for infection and as many as 100 million cases occur annually,¹ we have no antiviral drugs to treat it and no vaccines to prevent it. A closely related but much more lethal mosquito-borne virus, yellow fever, used to be one of the great scourges among humans. Although yellow fever is now largely controlled by vaccination, many regions are susceptible to a reemergence if the disease is introduced by travelers, and substantial recent problems with vaccine safety will no doubt change vaccination policy.

Both dengue and yellow fever are single-stranded RNA viruses in the family Flaviviridae, which includes West Nile virus and approximately 50 others. Substantial progress has been made in understanding the mechanism of the entry of these viruses into cells, the atomic structure of the viral envelope (see figure), the interactions between the molecular determinants and the host antibody, and the mechanism underlying the neutralization of the virus by antibodies.² The unraveling of virus–cell and virus–antibody interactions at the molecular level may lead to the development of antiviral drugs, improved vaccines, and tests for protective and pathological antibodies.

Dengue and yellow fever are endemic to and epidemic in tropical regions (see map). Both are zoonoses maintained in nature by transmission to humans from monkeys or mosquitoes that breed in tree holes. Infected humans have high blood levels of virus and can therefore infect vector mosquitos. After an incubation period of about 10 days, during which the virus replicates in the salivary-gland tissues of blood-feeding aedes mosquitoes, they can transmit the virus to another person. Throughout the tropics, the principal vector for endemic and epidemic spread, Aedes aegypti, has adapted to living among humans in domestic environments. Increasing human population density, urbanization, poor sanitation (creating breeding sites for larval mosquitoes), reinfestation (in the 1970s) of South America by A. aegypti after a successful eradication campaign, and the movement of infected persons by airplanes have contributed to a substantial increase in dengue incidence during the past 50 years.² A. aegypti mosquitoes are prevalent in the southern United States, which is therefore receptive to the introduction and spread of both dengue and yellow fever.
