Doctors have no specific drugs to treat dengue fever, a viral illness spread by mosquitoes that sickens 50 million to 100 million people worldwide each year. Instead, the only treatments they can recommend for this painful and sometimes fatal illness (20,000 deaths globally each year) are fluids, rest and non-aspirin pain and fever reducers.Now, researchers have identified cellular components in mosquitoes and in humans that dengue virus uses to multiply inside these hosts after infecting...

University of Adelaide researchers have shown they can predict the biggest population peaks of disease-carrying mosquitoes up to two months ahead. This should help the fight against outbreaks of serious mosquito-borne disease like dengue and Ross River fever by allowing efficient and cost-effective mosquito control, says ecologist Associate Professor Corey Bradshaw. "The risk of disease transmission is highest when mosquitoes are at their most abundant," says Associate Professor Bradshaw, who...

Massive urbanization expansions and a wildly uncontrolled global mosquito population are driving an increased rate of infection and death, according to an expert from the World Heath Organization (WHO). "Policymakers in the developing world didn't foresee the issue, they gave it a lot of lip service," Duane Gubler, a WHO adviser who has worked on tropical infectious diseases in Asia for over 30 years, told Reuters. "If you ask any minister of health in Southeast Asia, they will say dengue is...

The means by which most deadly malaria parasites are detected and killed by the mosquitoes that carry them is revealed for the first time in research published yesterday (March 5) in Science Express. The discovery could help researchers find a way to block transmission of the disease from mosquitoes to humans. Mosquitoes become infected with malaria when they feed on the blood of an infected person. Young malaria parasites then grow and develop inside the mosquito for two weeks. New human...

Number of cases of tropical disease continue to grow along US border, worldwide As vaccines against a virus that infects 100 million people annually reach late-stage clinical trials this year, researchers have developed a test to better predict whether a given vaccine candidate should protect patients from the infection, or in some cases, make it more dangerous, according to an article just published in the journal Clinical and Vaccine Immunology. Cases of tropical, mosquito-borne dengue...

Australian scientists say hoarding water as climate change intensifies might aid the dengue fever-carrying mosquito Aedes aegypti in extending its range. The lead author of the study, Michael Kearney of the University of Melbourne, said climate change and evolutionary change could act together to accelerate and expand the mosquito's range. But human behavior in the form of storing water to cope with climate change is likely to have an even greater impact. The potential direct impact of...

Ecologists have developed a new model to predict the impact of climate change on the dengue fever-carrying mosquito Aedes aegypti in Australia "“ information that could help limit its spread. According to the study, published in the new issue of the British Ecological Society's journal Functional Ecology, climate change and evolutionary change could act together to accelerate and expand the mosquito's range. But human behaviour "“ in the form of storing water to cope with climate...

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...

Flavivirus is a genus of the family Flaviviridae. This genus includes the West Nile Virus, Dengue Virus, Tick-borne Encephalitis virus, yellow fever virus, and quite a few others. Flaviviruses get their name from the yellow fever virus. Flavus means yellow in Latin. Yellow fever was named because if caused yellow jaundice in victims. Mosquitoes and ticks transmit these viruses by biting people. Human infections are usually incidental since humans are unable to replicate the virus. Yellow...

Aedes albopictus (Family Culicidae), the Asian Tiger Mosquito or Forest Day Mosquito, is characterized by its black and white striped legs and small, black and white body. It was native to south-east Asia, and occupied a habitat that spread from Madagascar eastward to New Guinea, and north to the latitude of Korea. The typical member of the Aedes albopictus has a length of about 5 mm. As with other members of the mosquito family, the female is outfitted with an elongated proboscis that she...
