With winter in full swing, it’s not just the cold we need to protect ourselves from—it’s also virus season. One virus making headlines recently is the H5N1 virus, also known as Highly Pathogenic Avian Influenza (HPAI) or bird flu.
Over the past few months, H5N1 has spread through populations of cows, from cows to cats, and even from cows to humans. While the risk of cats spreading this virus to people is currently very low, it serves as an important reminder to stay vigilant about disease prevention with our pets.
Why Winter Supports the Spread of Viruses
Winter provides ideal conditions for viruses to thrive and spread. Cold, dry air helps suspend viral particles for longer periods, increasing the chances of inhalation. Low humidity also makes these particles more stable, allowing them to remain infectious as they travel to a person’s nose or mouth.
This winter, along with H5N1, there are also reports of seeing increases in the circulation of RSV, COVID-19, influenza H1N1, influenza H3N2, and noroviruses. These overlapping viral threats make it more important than ever to adopt preventive measures to protect both human and animal health.
Best Practices for Preventing Disease Spread
Handwashing remains one of the most effective ways to prevent the spread of diseases. Whether you’re handling pets or interacting with people, washing your hands or using hand sanitizer immediately afterward can help reduce transmission. This is especially important before eating, drinking, or touching your face—even if the animal you’ve handled is your own pet.
Tips for Pet Owners During Virus Season
If you’re handling a pet you suspect may be sick, take precautions to protect yourself and your family. Avoid close contact, such as snuggling pets close to your face, and always wash your hands thoroughly after handling them. If you think your pet might be ill, contact your veterinarian promptly for guidance.
Additionally, keeping your pet’s environment clean and ensuring they are up-to-date on vaccinations can help reduce the risk of illness. Maintaining good hygiene practices, like cleaning food and water dishes regularly, can also contribute to their overall health.
Staying Healthy This Winter
To protect yourself, your pets, and your community this winter:
- Wash your hands frequently.
- Use hand sanitizer when soap and water aren’t available.
- Avoid touching your face, especially after handling animals.
- Stay home if you’re feeling sick.
- Keep a close eye on your pet’s health, and reach out to a veterinarian if you notice any signs of illness.
