Latest Dengue fever Stories
Number of cases of tropical disease continue to grow along US border, worldwide.
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.
Ecologists have developed a new model to predict the impact of climate change on the dengue fever-carrying mosquito Aedes aegypti in Australia â€“ information that could help limit its spread.
At least 167 cases of dengue fever, a dangerous and sometimes fatal mosquito-born illness, have been reported in Cairns on the northeast coast of Australia. Queensland health officials declared an epidemic Tuesday, The Brisbane Courier-Mail reported.
New research from Cornell University finds that Aedes aegypti mosquitoes, the kind that spread diseases such as dengue and yellow fever, change their wing vibrations as a mating symbol.
Old mosquitoes are normally a catalyst in the spread of disease, so scientists from Australia have found a way to kill mosquitoes naturally by breeding them to carry an insect parasite that causes earlier death.
Research conducted at The University of Queensland could contribute to the development of a vaccine and cure for West Nile virus and Dengue fever.
"Airport malaria" is a term coined by researchers to explain the more recent spread of malaria to areas such as the United States and Europe, which some scientists credit to warmer climate changes.
Air travel, international trade and globalized food production are helping "airport malaria" and other diseases spread to the United States, researchers say. Dr. James H.

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...
