What are the Symptoms of West Nile Fever?
Usually, people who are affected with WNV will not have any different symptoms, not even mild symptoms. However, the symptoms will include fever, headache, body aches, skin rash and swollen lymph glands. They can either last for several weeks or can get away on their own.
What is the Treatment for West Nile Fever?
As of now, there is no specific treatment for humans contracting WNV disease. The only way of preventing this virus is by protecting yourself from mosquito bites. The treatment will involve hospitalisation, intravenous fluids, respiratory support and protection from secondary infections for patients with neuro-invasive West Nile virus.
How to Protect from West Nile Fever?
Older people, children and those with the weak immune system can fall into the traps of West Nile fever. The safer way of protection is to avoid getting in contact with mosquitoes as they carry this virus. Scientist believes that climate change which causes milder temperatures could also help in spreading this disease.
