West Nile virus emerges in Merced County. How to take precautions
Mosquito samples that tested positive for West Nile virus in Merced County triggered a warning on Monday that residents should protect themselves against the disease.
The positive test was found in Planada, according to a news release from the Merced County Mosquito Abatement District.
The laboratory testing was conducted by the Center for Vector-Borne Diseases at UC Davis.
As of July 6, West Nile virus has been detected in 24 California counties, with 261 positive mosquito samples, 133 dead birds and 1 human case reported in the state, the news release said.
West Nile virus is spread through the bite of an infected mosquito.
“West Nile virus is here, and we need the public to take it seriously,” said Rhiannon Jones, Executive Director of the Merced County Mosquito Abatement District. “The best protection is staying aware of local risk levels, wearing repellent, and eliminating standing water around your house.”
Adults 55 and older are more vulnerable to the West Nile neurological illness. The risks of serious or life-threatening illness are higher for people with chronic health conditions.
Symptoms include fever, headache and fatigue, which may pass in a few weeks. In less than 1% of infections, the person develops serious illness, including meningitis, encephalitis, paralysis and even death.
With the warmer weather in July, more mosquitoes breed in standing water, serving to increase the risk of West Nile virus.
Here are some tips from the Mosquito Abatement District:
- Dump and drain: Remove standing water weekly from flowerpot saucers, buckets, birdbaths, pet bowls and other containers. Dispose of unused containers that may collect water.
- Maintain pools: Drain or treat unmaintained swimming pools. The District can help at no cost.
- Manage water in fields: Do not allow water to stand in pastures or agricultural fields for more than three days.
- Protect yourself: Wear EPA-registered repellent containing 30% DEET, Picaridin, or Oil of Lemon Eucalyptus.
- Stay Informed: Check the monthly Skeeter Meter and take extra precautions when risk levels increase.
