Texas reports first human case of avian influenza A (H5N1) in 2024

The H5N1 virus infects birds, causing high fever and mortality rates. Very rarely is human transmission seen. One such case has been reported in Texas.

The Texas Department of State Health Services confirmed the first human case of novel avian influenza A (H5N1) after exposure to infected dairy cattle.

The Centers for Disease Control and Prevention (CDC) maintains a low-risk assessment for H5N1 bird flu among the general public but urges caution for people exposed to infected birds.

Avian flu risk remains low for humans

Bird flu, which largely affects poultry birds, can affect some of the domestic animals, too.

Centers for Disease Control and Prevention (CDC) says, due to  pasteurization, commercial dairy products are not a health risk.

Commercial milk, not a risk

Uncooked or food products, such as unpasteurized (raw) milk or cheese made from raw milk, can pose a risk to those with HPAI A (H5N1) virus infection.

Human infections are linked to the highly pathogenic H5N1 virus and the bird flu virus (H7N9). Those infected with the virus must be monitored for 10 days after exposure to the symptoms.
