The Marion County Health Department on Monday confirmed its first case of West Nile virus in 2011. The finding came five days after the first case of the year was reported in Indiana. Last week, an Elkhart County woman died from the virus. There were three confirmed cases of West Nile in Marion County in 2010. Most people infected with West Nile become only mildly ill, but three people have died of the virus in Marion County since 2002.
