Latest Dengue fever Stories
A protein produced by mast cells in the immune system may predict which people infected with dengue virus will develop life-threatening complications.
With the help of a warning system which measures the risk of dengue incidence using precipitation and air temperature, it is possible to forecast the outbreak of dengue fever up to 16 weeks in advance.
As efforts to create a strong and effective vaccine for the dreaded dengue virus continue to hit snags, a new study from researchers at the La Jolla Institute for Allergy & Immunology offers surprising evidence that suggests the need for a revamped approach to dengue vaccine design.
Researchers have discovered that rising temperature induces key changes in the dengue virus when it enters its human host, and the findings represent a new approach for designing vaccines against the aggressive mosquito-borne pathogen.
Nearly 400 million people are infected with dengue fever each year, meaning that the world’s fastest-spreading tropical illness is affecting three times more people than the World Health Organization (WHO) had previously estimated.
Two Virginia Tech researchers successfully altered the eye color of a mosquito in an ongoing effort to develop genetic strategies with the specific goal to disrupt the transmission of disease such as malaria and dengue fever.
The mosquitoes that spread dengue fever tap into the domestic networks of humans, along with their bloodstreams.
A candidate dengue vaccine developed by scientists at the National Institutes of Health (NIH) has been found to be safe and to stimulate a strong immune response in most vaccine recipients.
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...
