5 Wildlife Diseases That Increase in Winter

During the winter months, wildlife such as squirrels, raccoons, and birds become more active in search of food and shelter. While these animals may seem harmless, those cute critters can carry diseases that can affect you and your family. Take a look at five wildlife diseases that increase throughout the winter months.

Lyme Disease

Although Lyme disease is transmitted through tick bites, winter conditions can indirectly increase exposure. As temperatures drop, wildlife such as squirrels, rodents, and birds move closer to homes and human activity areas in search of food and shelter. Ticks that feed on these hosts are then more likely to be carried into yards or structures, increasing the chance of human contact.

Rabies

Rabies cases often rise in winter because many small mammals experience stress from food scarcity and cold weather. This stress can weaken their immune systems, making infected animals more symptomatic and more likely to display unusual or aggressive behavior. In addition, wildlife may venture closer to homes in search of food, increasing the likelihood of encounters.

Hantavirus

Hantavirus risk increases in winter as rodents seek warm, sheltered environments—often sheds, attics, crawl spaces, and even homes. Increased rodent activity leads to more droppings and urine in enclosed areas. When these dry out, the virus can become airborne and spread when the area is disturbed.

Avian Influenza

Avian influenza becomes more prevalent in winter due to seasonal bird migration and crowding. Birds gather more densely around food sources and shelter, which facilitates rapid virus spread within flocks. These infected birds may move closer to residential areas during harsher weather, increasing potential exposure.

Leptospirosis

Leptospirosis cases can rise in winter because wildlife, particularly rodents, are more likely to urinate near homes as they search for reliable food and water sources. Cold, damp winter conditions allow the bacteria to persist longer in soil and standing water. Humans who come into contact with contaminated soil or water have a higher risk of infection during this season.
