Can Possums Get Rabies

Possums, also known as opossums, are North America's only marsupial, and they have a unique reputation for being immune to certain diseases. However, the question remains: can possums get rabies? To answer this, we need to delve into the world of possum biology and the specifics of rabies transmission.

Rabies Transmission and Possums

Rabies is a viral disease that affects the nervous system of mammals, including humans. It is primarily spread through the saliva of infected animals, usually through a bite. The virus attacks the central nervous system, causing inflammation of the brain and eventually leading to death if left untreated. While many mammals can contract and transmit rabies, possums have a lower body temperature than most mammals, which makes it difficult for the rabies virus to survive and replicate within them.

Possum Immunity to Rabies

Possums have a natural resistance to rabies due to their low body temperature, which averages around 94°F to 97°F (34°C to 36°C). The rabies virus thrives in warmer temperatures, typically between 98°F and 100°F (36.7°C and 37.8°C). This temperature difference makes it challenging for the virus to replicate within a possum’s body, reducing the likelihood of infection. Additionally, possums have a strong immune system that helps to fight off the virus if they are exposed.

Studies have shown that possums can be infected with rabies under laboratory conditions, but this is extremely rare in the wild. In fact, according to the Centers for Disease Control and Prevention (CDC), there have been no documented cases of rabies transmission from a possum to a human in the United States. This suggests that the risk of contracting rabies from a possum is extremely low.

Prevention and Safety Measures

Although the risk of contracting rabies from a possum is low, it is still important to take precautions when dealing with wild animals. If you encounter a possum, it is recommended to keep a safe distance and avoid touching or handling it. If you must handle a possum, wear protective gloves and wash your hands thoroughly afterward. It is also crucial to ensure that your pets, especially dogs and cats, are up-to-date on their rabies vaccinations to prevent the spread of the disease.

What to Do If Bitten by a Possum

If you are bitten by a possum, it is essential to seek medical attention immediately. While the risk of rabies transmission is low, it is still possible to contract other diseases or infections from the bite. Your healthcare provider may recommend post-exposure prophylaxis (PEP) as a precautionary measure, which includes a series of injections to prevent rabies infection.

In conclusion, while possums can theoretically contract rabies, the risk of transmission to humans is extremely low due to their natural resistance and low body temperature. However, it is still crucial to exercise caution when dealing with wild animals and take preventive measures to ensure safety.
