West Nile Virus is a disease which is spread by mosquitoes and for the most part is not a serious disease.  Often there are no symptoms but sometimes if an infected mosquito bites somebody it can lead to inflammation of the brain, spinal cord or the tissues which surround the brain and spinal cord.

The West Nile Virus is caused when a mosquito feeds on an infected bird and then bites an animal or human.  Most of the time people with West Nile Virus have no symptoms but some people experience symptoms which include headache, muscle ache, loss of appetite, fever, nausea, vomiting, back pain, abdominal pain, sore throat and diarrhea.  The symptoms will usually surface roughly three to 14 days after the infected mosquito bite and will last for approximately three to six days.

There can be complications however, and sometimes the virus can cause an infection of the brain and nervous system.  Symptoms of this would include severe headaches, high fever, stiff neck, lack of co-ordination, muscle tremors, convulsions, coma, disorientation, coma or even partial paralysis.

West Nile Virus is not serious if symptoms are mild.  However, if the virus spreads to the brain or spinal cord it can lead to brain damage or death.

The best way to avoid the virus is to protect against mosquito bites at all times when away.  It is advisable to check whether the virus is present in the country you are visiting and take extra precautions against being bitten.
