With the recent confirmation of Missouri’s first human case of H5N1 Avian Flu confirmed by the Department of Health and Senior Services, the City of St. Louis Department of Health is encouraging extra vigilance and safety precautions by residents who own or frequently come into contact with domestic birds, such as chickens and ducks, or wild birds.

Wild birds, including crows and various species of songbirds, are the most prominent carriers of the avian flu virus, and evidence has shown that these animals can spread the disease to humans. If you own a flock of chickens, the Department of Health recommends the following precautions:

  • Wear protective gear such as gloves and a facemask when coming into direct contact with the birds or their living environment
  • Wash hands thoroughly with soap and warm water for at least 20 seconds after handling the animals or items belonging to them
  • Keep other animals such as dogs or cats away from the birds
  • Report deceased birds that recently suffered an illness to the Missouri Division of Animal Health at (573) 751-3377 or animal.health@mda.mo.gov. Carefully wrap the bird in a plastic bag so that it can be submitted for laboratory testing

Avian flu is most commonly transmitted by direct contact with animals that carry it, whether or not they are displaying symptoms of illness. It is very rare for the disease to be transmitted from person to person.

Household pets, primarily cats, are particularly susceptible to avian flu because of predation of wild birds. If you notice your cat or dog suddenly developing respiratory symptoms, contact your vet immediately - a quick response increases the animal’s chance for recovery and your vet will want to confirm or rule out avian flu.

If you find a deceased wild bird in your yard, place it in a sealed plastic bag for disposal. The department strongly recommends wearing a face mask and gloves when handling deceased birds and washing your hands for at least 20 seconds afterward.
