Health Department Recommends Extra Precautions for West Nile

After a Hamilton County resident tested positive for West Nile virus – the second human case reported in Indiana this summer – health department officials are recommending extra precautions.

The mosquito-borne disease can cause illness in humans, birds, and other animals.

“Most people infected with West Nile virus have no symptoms or only mild flu-like symptoms which can include fever, headache, body aches, joint pain, vomiting, diarrhea, or a rash,” says Dr. Charles Harris, Hamilton County’s Health Officer. “Some people will develop a more severe form of the disease affecting the nervous system, including inflammation in the brain and spinal cord, muscle paralysis, or even death.”

People older than 60 years old and those with weakened immune systems are at higher risk of severe West Nile virus disease. People who think they may have West Nile virus should see their healthcare provider.   

Hamilton County confirmed its first WNV positive mosquito sample in June. Since then, the Health Department has increased surveillance and testing throughout the county. It has also conducted mosquito spraying to decrease the number of adult mosquitoes.

“Warm, humid weather and recurring storms have created perfect conditions for mosquitoes this year,” says Amy Ballman, Director of Environmental Health at the Health Department. “The season is longer and populations are growing faster – making this a year to be especially cautious.”

Additional information about the case in the county will not be released to protect patient privacy.
