Different species can be susceptible to different viral infections, but some viruses affect multiple species, including humans, cats, dogs, and birds.
Examples:
- Influenza: Can infect mammals and birds, including humans, cats, dogs, chickens, and ducks.
- Rabies: Can be transmitted to a wide range of mammals, including humans, cats, dogs, raccoons, and bats.
- Zoonoses: Diseases like SARS, MERS, and COVID-19 originated in animals and spread to humans, sometimes affecting domestic animals.
- Coronaviruses: Some infect multiple species, such as canine and feline coronaviruses, with occasional cross-species cases.
Susceptibility and severity vary by age, immune status, and health conditions. Different strains also vary in host range and virulence. Good hygiene, proper vaccination, and timely medical care help protect both humans and animals.
