Wet Spring Raises Hantavirus Risk in U.S. Amid Rodent Population Growth
Periods of heavy rainfall during spring have led to increased rodent activity, raising concerns about potential exposure to hantavirus in the United States. Hantaviruses, carried by rodents, can spread to humans through contact with infected urine, droppings, or saliva, as well as through airborne particles from contaminated nesting materials. The Centers for Disease Control and Prevention (CDC) has highlighted that environmental factors, such as precipitation linked to El Niño events, can indirectly increase exposure risk by boosting rodent populations. AccuWeather meteorologists predict a 30% chance of a super El Niño developing by the end of the Atlantic hurricane season, which could further influence rainfall patterns. Health officials emphasize that the risk to the general public remains low, but caution is advised during spring cleaning in areas with signs of rodent activity.
