Dec 20, 2024, 01:57 PM

The H5N1 avian influenza, commonly known as bird flu, has led to the deaths of multiple cats in Los Angeles, with raw meat consumption identified as the likely cause. Los Angeles County has confirmed the presence of the virus in at least two cats and is investigating three more suspected cases. Additionally, a raw milk warning has been issued in relation to the virus. The outbreak of H5N1 among dairy herds in California has escalated, with the virus detected in 659 herds, prompting Governor Gavin Newsom to declare a state of emergency. The rapid spread of the virus in California suggests unknown transmission pathways, raising concerns about the effectiveness of current biosecurity measures. The World Health Organization has emphasized the need for stronger biosecurity and surveillance on farms to protect both animals and humans from the virus. There have been 61 reported human cases of bird flu in the U.S. since April, and the first severe case was reported in Louisiana, where a person was hospitalized after exposure to sick and dead birds in a backyard flock. The CDC maintains that the risk to the general public remains low, but the situation underscores the importance of vigilance and preparedness for potential pandemics.
