West Nile in Arizona: Man shares partner's health fight to educate others

Chris Silva's significant other Karen has been hospitalized since June 4 after experiencing flu-like symptoms. Then came meningitis and then the West Nile Virus diagnosis. Chris says now Karen has encephalitis, which is the swelling of the brain with very little activity. "She had flu-like symptoms, we got her into the hospital the next thing you knew our worst nightmare came true," said Chris. "Be careful with mosquitoes because none of us think much of it, but one mosquito can do incredible damage and we had no idea."
