Mosquito Net
A mosquito net is a type of meshed curtain or cloth that is circumferentially draped over a bed or a sleeping area to offer the sleeper barrier protection against bites and stings from mosquitos, flies, and other pest insects, and thus against the diseases they may carry. Examples of such preventable insect-borne diseases include malaria, dengue fever, yellow fever, zika virus, Chagas disease, and various forms of encephalitis, including the West Nile virus. To be effective, the mesh of a mosquito net must be fine enough to exclude such insects without obscuring visibility or ventilation to unacceptable levels. The netting should be made of stiff cotton or synthetic thread to allow the movement of air. A white net allows the user to see mosquitoes against the background. Netting with 285 holes per square inch is ideal because it is very breathable but will prevent even the smallest mosquito from entering. It is possible to increase the effectiveness of a mosquito net ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Nile Virus
West Nile virus (WNV) is a single-stranded RNA virus that causes West Nile fever. It is a member of the family ''Flaviviridae'', from the genus ''Flavivirus'', which also contains the Zika virus, dengue virus, and yellow fever virus. The virus is primarily transmitted by mosquitoes, mostly species of ''Culex''. The primary host (biology), hosts of WNV are birds, so that the virus remains within a "bird–mosquito–bird" Transmission (medicine), transmission cycle. The virus is genetically related to the Japanese encephalitis family of viruses. Humans and horses both exhibit disease symptoms from the virus, and symptoms rarely occur in other animals. West Nile virus was not named directly after the Nile River, but rather, after the West_Nile_sub-region, West Nile district of Uganda where the virus was first isolated in 1937. Structure Like most other flaviviruses, WNV is an Viral envelope, enveloped virus with icosahedral symmetry. Electron microscope studies reveal a 45–5 ...
