Massachusetts officials announced Wednesday that bird flu is now considered to be “widespread” in the state and urged the public to avoid handling birds or other animals that are dead or appear sick.

Officials said risk to humans remains low, but the state's public health veterinarian said pet cats are "very susceptible" to the bird flu and can become "seriously ill."

Bird flu appears to be widespread in Massachusetts, state health and environmental officials said Wednesday. The Division of Fisheries and Wildlife (MassWildlife), the Massachusetts Department of Agricultural Resources (MDAR) and the Massachusetts Department of Public Health (DPH) said bird flu -- also known as highly pathogenic avian influenza (HPAI) -- is suspected to be the cause of death in cases of both wild and domestic birds in several Massachusetts municipalities.
