The victim was an older person with underlying health problems, according to a news release from Tarrant County Public Health. "The best protection against West Nile virus - and other mosquito-borne illnesses including Zika - is to avoid being bitten by mosquitoes".

Ada County Mosquito Abatement will treat one square mile around the areas that have tested positive and is actively going through routine testing of all sites.

The health department sets 50 traps throughout the county each week in order to monitor the mosquito population and to identify West Nile Virus.

"It's imperative that county residents be aware that WNV (West Nile virus) is active and to avoid mosquito bites by whatever means necessary", said mosquito district manager Matt Ball.

There are no reports of humans in Pennsylvania who have contracted WNV this year, according to the Pennsylvania West Nile Virus Control Program.

Symptoms of WNV infection are often mild and may include fever, headache, nausea, vomiting, a rash, muscle weakness or swollen lymph nodes.
