How is the virus shed by companion animals?
Top A: In experimentally infected cats, the virus was detected by swabbing nasal, pharyngeal (throat), and rectal tissues. “Shedding,” as it applies to viruses, means that the animal’s secretions and/or feces contain viral particles that may infect other animals or people. Although it has not been confirmed, it is reasonable to assume that virus may be shed in oral and respiratory secretions and feces from naturally infected cats. Evidence suggests that the H5N1 highly pathogenic avian influenza (HPAI) virus is not shed in the same quantities from cats as it is from birds, and that the risk posed to humans by infected cats is low. Based on what is known from experimental infection and a single case of clinically apparent avian influenza in a dog, the risk of transmission from this species should also be very low. Practicing good hygiene (e.g., washing hands and frequently disinfecting surfaces) and limiting contact with pets showing signs or respiratory illness (e.g., coughing, sneezin
