West Nile Virus Vaccines

This first discovered virus was confirmed as West Nile virus in Uganda in East Africa in 1937. West Nile virus is a single-stranded RNA virus in the Flaviviridae family and is part of the Japanese encephalitis virus antigen complex. It can be seen in both tropical and temperate areas. It is known to infect vertebrates and certain insects. The most common way to infect humans is to infect mosquitoes. West Nile virus attacked the United States in New York in the summer of 1999.

West Nile encephalitis is a brain infection caused by a virus called West Nile virus. This virus was first discovered in Uganda in 1937 and is common in Africa, West Asia and the Middle East. Except for Alaska, all US states reported West Nile virus infection. "Encephalitis" refers to brain inflammation. The most common cause of encephalitis are viral infections and bacterial infections, including viral infections that are transmitted by mosquitoes. West Nile virus infection is also known as West Nile fever or West Nile encephalitis. This virus is an arbovirus (ARrthropod-BOrne's arbo because many insects are arthropods). It is a member of Flavivirus and Flaviviridae. Other flaviviruses that affect humans include yellow fever, dicavirus, dengue. Human and veterinary cases of West Nile Virus are reported electronically to ArboNET by state and local health authorities

There is currently no vaccine available for the prevention of West Nile virus. A serious patient with West Nile virus is undergoing supportive care at a hospital. This involves not helping the disease directly, but also helping the body fight itself. People infected with West Nile virus may receive intravenous (intravenous) infusion and respiratory support (via ventilator). Scientists are working on the West Nile virus vaccine. In the absence of an available vaccine, experts recommend that you protect yourself against viruses by preventing people from getting bitten by mosquitoes. The mosquito season has the highest risk of being infected with West Nile. In Canada, the high risk season is from the middle of April to the end of September or October.

The field of vaccine development is rapidly growing. Vaccines have been developed to prevent diseases caused by pathogens that previously had no vaccine, such as West Nile virus. Existing vaccines provide simpler routes of administration (eg, inhalation of influenza vaccines) and have been reconstituted to provide side effects (eg, rotavirus and diphtheria / tetanus / acellular pertussis vaccine). Combinations have been developed to reduce the number of vaccinations, including newly approved FDA hepatitis A / hepatitis B vaccine. In addition, new concepts of vaccination, including recombinant subunits, reassortant virus technology, live vectors and naked DNA technology seems to be precisely visible.
