Mosquito pool tests positive for West Nile virus in San Antonio

SAINT ANTONY – A mosquito pool in San Antonio has tested positive for West Nile virus, according to the City of San Antonio Metropolitan Health District.

Metro Health lab results confirmed that a mosquito pool near Ray Ellison Boulevard and the 410 loop on the southwest side tested positive for the virus on June 22.

The infected sample was taken on June 7, according to Metro Health’s website.

Pest and fogging services will be held next week in surrounding areas by Metro Health’s vector control program, officials said in a news release.

Increased rainfall can lead to increased hatching of mosquito eggs.

Metro Health suggests the following safety measures to help reduce mosquito populations:

  • Eliminate standing water – These actions can help reduce the number of mosquitoes in areas where people live. After heavy rains, people should empty and scrub, turn over, cover or dispose of containers with water.

  • Improving Sanitation – When water is contaminated with organic matter (i.e. animal waste, grass and leaves), the chances of mosquito larvae surviving may increase. The contaminated material provides food for the larvae.

  • Protect yourself – Using an insect repellent containing DEET or picaridin on skin not covered by clothing is very important. Safety measures when using a repellent include:

    • Spray insect repellent on clothing (mosquitoes can bite through thin clothing)

    • Insect repellents should not be used on young children

    • Wear long-sleeved shirts, long pants, and socks to protect exposed skin at dusk and dawn, which is when mosquitoes are active

    • Using air conditioning or ensuring that there are screens on all doors and windows to prevent mosquitoes from entering an individual’s home

According to the Centers for Disease Control and Prevention, West Nile virus is the leading cause of mosquito-borne disease in the continental United States and is transmitted primarily to people through the bite of an infected mosquito.

It is most commonly transmitted to humans through the bite of an infected mosquito.

Most people, up to 80%, do not show signs of infection or develop symptoms of the virus, the CDC’s website says.

Symptoms include fever, headache, body aches, joint pain, vomiting, diarrhea, or rash.

Most people with febrile illness due to West Nile virus recover fully, but fatigue and weakness can last for weeks or months, according to the CDC.

“About 1 in 150 people infected develop a serious disease affecting the central nervous system such as encephalitis (inflammation of the brain) or meningitis (inflammation of the membranes that surround the brain and spinal cord),” CDC officials said. .

People over 60 are at higher risk of serious illness. People with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and those who have had organ transplants are also at higher risk.

There is no vaccine or medication to prevent or treat West Nile virus.

Future pools of West Nile virus positive mosquitoes will be updated on the Metro Health website.
