West Nile virus: Maricopa County reports 1st death of season
1st West Nile death of 2025 reported
Maricopa County has recorded the first deadly case of the West Nile Virus in 2025, and this comes as health officials say the number of mosquitoes trapped, along with positive tests, are on the rise. FOX 10's Kenzie Beach reports.
PHOENIX - Maricopa County health officials have confirmed its first West Nile virus death of the season.
What we know:
The person who died was identified as an older adult with underlying health conditions. So far this year, 17 human cases of West Nile have been confirmed in the county.
"We're seeing elevated numbers of mosquitoes, both the mosquitoes that are being trapped, as well as testing for West Nile virus," said Maricopa County Health Department Chief Medical Officer Dr. Nick Staab.
Dig deeper:
Health officials say West Nile is typically spread through infected mosquito bites. Some symptoms of the virus include feer, headache and body aches. In rare cases, officials say West Nile can cause severe complications, like meningitis, which could lead to paralysis, disability or death.
Older adults and people with underlying health conditions are at greater risk of severe illness.
West Nile Virus cases on the rise
Health officials are already tracking West Nile Virus cases in several states, including Arizona. Earlier this month, Maricopa County Environmental Services reported an increase in mosquito activity in the county.
Pest control experts say the monsoon season creates the perfect recipe for mosquitoes to multiply.
"Mosquito eggs can last for up to 2 to 3 years, just waiting for some rain," said Mosquito Squad Scottsdale owner Chuck Wells. "They want it warm. If they get some moisture once in a while for the eggs. Bang!"
Wells said lawn irrigation is common places for mosquitoes. They can even high under artificial turf.
What you can do:
Officials advise the public to follow these precautions to avoid mosquitoes:
- Use insect repellent containing DEET, Picaridin, or other EPA-registered repellents.
- Drain and remove containers that hold water from around your home where mosquitoes can breed, such as plastic covers, buckets, old tires, plant trays, pet bowls and toys.
- Scrape the sides of the dish or inside potted plants where mosquitoes lay eggs.
- Make sure doors and windows have tight-fitting screens and no holes.
- Wear lightweight clothing that covers your arms and legs if it's not too hot.
- Ensure that swimming pools and decorative water features are maintained
