Mosquito Diseases - West Nile Virus
What is West Nile Virus?
Originating in Uganda, the first recorded North American outbreak of West Nile virus was in 1999. In 2002, more than 4,000 North Americans became ill after being infected with the virus.
What are the symptoms?
In mild cases of the West Nile virus, flu-like symptoms such as fever and headache may appear. For those with weaker immune systems, more serious health complications may follow infection. Such complications include headache, high fever, nausea, vomiting, difficulty swallowing, drowsiness, muscle weakness and paralysis and such fatal illnesses as meningitis and encephalitis.
Who is at risk?
However, it is important to remember that anyone exposed to mosquitoes in an area where West Nile virus has been detected is at some degree of risk for infection.
