Arbovirus is the name given to Arthropod-borne viruses, that is, viruses that are transmitted to vertebrates, such as people and mammals, by blood-feeding insects called arthropods, such as mosquitoes. Vertebrate infection occurs when the infected insect bites an animal or person and takes a blood meal.
An experimental research carried out in Sant Cugat del Vall-s and Rub-, coordinated by researchers from UAB, assessed the efficacy of a combination of strategies to reduce the population of tiger mosquitos.
The combination of three complementary measures to eradicate tiger mosquitos - avoid having stagnant water, using insecticides to eliminate larvae and adults, and removing rubbish - reduces more than half the number of tiger mosquitos, according to a research coordinated by researchers at Universitat Autonoma de Barcelona.
Chikungunya is transmitted by mosquitoes of the genus Aedes. The disease is spreading in the world and periodically sparks new outbreaks. Africa, Asia, the Indian Ocean and even Southern Europe are now affected.
Researchers at the University of Texas Medical Branch have discovered how a key protein switch allows Chikungunya Virus (CHIKV) to spread to new vectors.
Developing new strategies to prevent and control yellow fever and dengue fever has become more possible with the completion of the first draft of the genome sequence of Aedes aegypti mosquito by scientists led by Vishvanath Nene at The Institute for Genomic Research (TIGR) and David Severson at the University of Notre Dame.
Los Angeles health officials have issued a statement urging the public to take precautions against mosquitoes after crows in the county tested positive for the West Nile virus. "These findings are a clear warning that the virus is continuing to circulate and amplify in the environment. Now is the time to take precautions," said Steve West of the San Gabriel Valley Mosquito and Vector Control District.
