Montgomery County testing mosquitoes for West Nile virus after death

Following the confirmation of a West Nile virus related death and Montgomery County’s second possible case, the Precinct 3 Mosquito Abatement Team is on high alert as they continue to test mosquito samples.

On Friday, the Montgomery County Public Health District announced the death of a man in his 70s who lived in the 77381 ZIP code. While the man did have other medical conditions but the death was classified as a probable West Nile virus case. A woman in her 60s who lives in the 77382 ZIP code has been confirmed as the second case.

At this time in 2019, the county had no cases of West Nile virus, health officials said.


Cody Grimes, manager of projects and logistics for the Precinct 3 office, said the announcement of the death and second case did not prompt spraying in those ZIP codes. Grimes explained that due to the time to get the confirmation on the cases, crews had already responded to those ZIP codes when the mosquito sample returned positive.

He noted currently there are no West Nile positive samples in South County.

“We do spray when we get positive mosquito samples,” Grimes said, adding mosquito season is winding down. “There hasn’t been anything abnormal this year.”

West Nile virus can cause serious disease and is commonly spread by infected mosquitoes, according to MCPHD. People typically develop symptoms between three and 14 days after they are bitten. According to the CDC, approximately 80 percent of people who are infected will not show any symptoms at all.

Milder symptoms include fever, headache, body aches, nausea, vomiting and, sometimes, swollen lymph glands or a skin rash on the chest, stomach and back. These symptoms can last up to several weeks. Serious symptoms that account for less than 1 percent of those infected can include high fever, headache, neck stiffness, disorientation, coma, tremors, seizures or paralysis. These symptoms can last for several weeks and neurological effects may be permanent.

Anyone who develops symptoms of severe West Nile virus illness, such as unusually severe headaches or confusion, should seek medical attention immediately. However, the majority of milder illnesses improve on their own.

According to the CDC, the most effective way to avoid West Nile virus is to prevent mosquito bites. Avoid bites by using insect repellants, wearing protective clothing when outdoors and emptying standing water outside of your home.
