A computer model of the spread of West Nile virus was able to predict areas where human cases would be concentrated, especially around Sacramento in 2005. The success of the model, say researchers, depended on its focus on biological factors and on a high volume of reports from members of the public. A computerized epidemiological model of the spread of the mosquito-borne West Nile virus in 17 counties of California in 2005 successfully predicted where 81.6 percent of human cases of the...

An experimental research carried out in Sant Cugat del Valls and Rubí, coordinated by researchers from UAB, assessed the efficacy of a combination of strategies to reduce the population of tiger mosquitos (Aedes albopictus). The research began in February 2008. The research focused on monitoring eggs found in small experimental traps. Researchers observed that for the first time, the number of eggs diminished after applying the measures. The strategies began with a visit to...

Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a team of biochemists at the University of Arizona found Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered. The approach could be used as an additional strategy in the worldwide effort to curb...

Health officials have issued a mosquito-borne illness advisory after a positive test for West Nile Virus Orlando, FL (PRWEB) July 14, 2011 Health officials in Seminole County, Florida, have issued a mosquito-borne illness advisory after a positive test for West Nile Virus in several chickens. Recent rains and summer heat have made Florida, and other parts of the country, prime breeding grounds for mosquitoes, which can spread West Nile virus, dengue fever, encephalitis, canine heartworm and...

Guest edited by Brandeis professor Donald Shepard, it contains 7 original studies co-authored by Brandeis researchers The ten studies in this special issue document the substantial and growing burden of dengue in the Americas, Africa and Asia, and the burden of a chikungunya outbreak in India. Luiz Tadeu Moraes Figuedo's paper on dengue in Brazil confirms the country's worsening trend; from 1999-2009, where cases rose at 6.2% per year and dengue deaths at 12.0% per year. Carmen Perez and...

JAKARTA, Indonesia, June 14, 2011 /PRNewswire/ -- The Association of Southeast Asian Nations (ASEAN) launched the first ASEAN Dengue Day today in Indonesia, with related events occurring throughout the ASEAN member states. The date was chosen to coincide with the month in which dengue infections in the region typically peak. ASEAN Dengue Day is a new enterprise in the fight against dengue, aiming to: Increase public awareness of dengue to help to reduce the risk of dengue transmission...

Dengue virus circulating between monkeys and mosquitoes could emerge to cause human outbreaks More than a thousand years ago, somewhere in Southeast Asia, a fateful meeting occurred between a mosquito-borne virus that infected mainly monkeys and a large, susceptible group of humans. The result: the world's first outbreak of dengue fever. Today, dengue virus "” which can produce high fever, excruciating joint pain and even death "” has spread throughout tropical Asia, Africa and...

In a dramatic breakthrough in the battle against malaria, researchers have identified a low-cost chemical that interferes with a mosquito's ability to detect humans, scientists said on Wednesday. Experts hope the findings could help develop the next generation of mosquito traps and repellents, which could confuse, deter or trap the insects. The chemicals consist of odor molecules that disrupt carbon-dioxide sensors that alert mosquitoes to exhaled human breath, which signals the presence of a...

Female blood-feeding mosquitoes, some species of which can transmit deadly diseases such as malaria and dengue to humans, largely find their human blood meals by detecting carbon dioxide emitted when people exhale. In a new study funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, a research team led by Anandasankar Ray of the University of California, Riverside, identified three types of odor molecules that disrupt the...

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...
