West Nile virus found in Bernalillo County mosquitoes
Health officials urge measures to protect against mosquito bites
Published
Health officials have found mosquitoes infected with West Nile virus in Bernalillo County, posing a potential risk of illness to people in the area, the New Mexico Department of Health reported Tuesday.
No human cases have been reported this year in New Mexico, but officials are urging residents to take precautions to avoid mosquito bites.
The infected mosquitoes were collected via routine monitoring at sites near the Rio Grande, health officials reported.
鈥淲hile mosquitoes are not currently widespread due to dry conditions, we continue to see them concentrated in wet areas,鈥� said Nick Pederson, manager of the city of Albuquerque Urban Biology Division. 鈥淎s we enter the monsoon season, we are asking residents to check their yards and neighborhoods for standing water that could become a mosquito breeding source.鈥�
Mosquitoes with West Nile virus can pass the virus to humans and other animals, including birds and horses, through a bite. People bitten by an infected mosquito may not develop symptoms, but people over 50 and those with weakened immune systems are at higher risk of serious illness.
The state reported 52 human cases and 11 deaths from West Nile illness in 2025. Symptoms can include headache, fever, muscle and joint aches, nausea and fatigue. Serious symptoms include neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis.
To reduce risks, use insect repellents that contain DEET, picaridin, IR3535 or oil of lemon eucalyptus or para-menthane-diol. Drain the water in birdbaths, wading pools and saucers under potted plants weekly. Keep windows and doors closed if not screened.
