A deadly virus that can cause severe illness or death has been making headlines after a recent case in New Mexico. Hantavirus is spread through contact with infected wild rodents, and while exposure is rare, people should be cautious around these animals.
In San Diego County, where wild rodents are common, the County Department of Environmental Health and Quality’s Vector Control Program tests for hantavirus annually. In 2024, there were 25 detections, and seven mice have tested positive so far in 2025.
Symptoms of hantavirus can develop between one to eight weeks after exposure and include severe muscle aches, chills, fever, headache, nausea, vomiting, and difficulty breathing. If you suspect you’ve been exposed, seek medical attention immediately.
To prevent infection, people should seal external holes to keep rodents out and eliminate infestations promptly. Using “wet cleaning” methods is crucial when dealing with infected areas. This involves:
– Ventilating the area for 30 minutes before cleaning
– Wearing rubber gloves and spraying disinfectants on dead rodents and contaminated surfaces
– Cleaning with a sponge or mop soaked in disinfectant, then sealing and disposing of affected materials
– Washing hands thoroughly after handling infected material
It’s essential to follow these precautions to avoid exposure to hantavirus. For more information, contact the County Department of Environmental Health and Quality Vector Control Program at (858) 694-2888 or visit their website.
