ELKHART, Ind.--- Pools of mosquitoes in Elkhart County tested positive for the West Nile Virus. The Indiana Department of Health expects West Nile could spread throughout Michiana. 

Health officials say that most people who get West Nile don't develop symptoms. However, for those who do, those symptoms include, fever, headache, body ache, and joint pain. 

In extreme cases, the virus could develop into the West Nile Flu, a disease that attacks the nervous system and could cause paralysis or death.

Officials advise staying indoors between dusk and dawn, and covering exposed skin and using repellent when going outside. The EPA has a list of repellent alternatives on its website for those who are concerned with using DEET or other chemicals.
