West Nile Virus (WNV)
West Nile Virus (WNV) is an arbovirus most commonly spread to people by infected mosquitoes. It was first detected in eastern United States in 1999 and since then cases have been reported in all states of the continental U.S. The virus was first detected in Long Beach among mosquitoes in 2003, and the first human case was reported a year later in 2004.
Most people who become infected with WNV do not develop any symptoms, however, approximately 1 in 5 people who are infected will develop a fever with symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. West Nile Virus has also been found to cause neurologic illness such as encephalitis or meningitis in approximately 1% of people who are infected. Anyone living in an area where WNV is present can become infected, however people over the age of 50 have a higher likelihood of becoming sick and are more likely to develop serious symptoms.
