Hantavirus, a family of viruses that can lead to severe illness or death, has recently gained attention following the death of Betsy Arakawa, wife of actor Gene Hackman. She succumbed to hantavirus pulmonary syndrome as confirmed by New Mexico medical investigators.

Though rare, exposure to hantavirus remains a concern. People are advised to exercise caution around wild rodents due to the absence of a cure or vaccine for the virus. In San Diego County, finding hantavirus in wild rodents is not unusual. The County Department of Environmental Health and Quality’s Vector Control Program regularly tests these animals to monitor hantavirus activity. In 2024, there were 25 detections, and so far in 2025, seven mice have tested positive. However, human contact with infected rodents is infrequent since these animals tend to avoid humans naturally.

Symptoms typically appear one to eight weeks after exposure and include flu-like signs. Immediate medical attention is recommended if exposure is suspected.

Infection occurs when people come into contact with areas invaded by wild rodents. These animals excrete the virus through urine, feces, and saliva which can become airborne once dried and inhaled by humans.

To prevent infection, "wet cleaning" methods should be employed when dealing with rodent infestations in living spaces. This involves using bleach or disinfectants along with rubber gloves and bags instead of sweeping or vacuuming which could aerosolize the virus.
