What is West Nile Virus? West Nile Virus is a strain of encephalitis, a serious, untreatable and sometimes deadly viral disease that can be carried by some mosquitoes. The virus which was first found in Uganda in 1937, was discovered in US in 1999 and has spread across America. In 2002 it was responsible for more than 200 deaths in the U.S., according to the Centres for Disease Control. The climatic change in the UK may bring West Nile Virus to Britain. Since the mosquito larvae grow in stagnant (dirty) and shallow water, the North West and parts of Wales are most likely to be affected because of the higher rainfall in these areas. Contracting West Nile Virus from a mosquito bite is extremely rare. However, it can be especially dangerous if contracted by people with an impaired ability to fight the virus, such as the elderly, young children, and those with conditions that compromise the immune system. Symptoms of West Nile Virus West Nile symptoms usually appear between five and 15 days after a bite from an infected mosquito. In the early stages, these symptoms may include: Severe headaches Fever Nausea and vomiting Disorientation Chills Muscle aches, pain, stiffness, or all three If you experience any of these symptoms after being bitten by a mosquito, you should immediately seek medical attention.
