An estimated 80% of West Nile virus patients are asymptomatic (Sejavar, 2014). This can be explained by the nature of the attack of the disease against the host immune system and to what extent the host can handle it. Another reason is due to differences in West Nile virus strain and its toxicity (Jeha & Sila, 2009). Most patients with symptoms with WNV suddenly develop congenital fever, in other words West Nile Fever (WNF) (Jeha & Sila, 2009). Another serious complication caused by WNV is that approximately 1% of the infections in the infected population are diseases affecting the nervous system due to the invasiveness of the disease.
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
West Nile virus West Nile virus is a virus in which mosquitoes that cause encephalitis (brain inflammation) or meningitis (brain and spinal cord inflammation) are born. The West Nile virus is stabbed by an infected mosquito and infects humans. Bite the bird carrying the virus and infect mosquitoes. You can not get the West Nile virus from this sick person. Young adults are less likely to be at risk of West Nile virus than elderly people. The possibility of being infected with West Nile virus is very low, but in most cases it occurs to people over the age of 50. People of this age group, especially the elderly, are also prone to serious diseases such as encephalitis and meningitis. When infected
