Colorado Dairy Worker Tests Positive for H5N1 Bird Flu Virus
Updated July 3, 2024
A Colorado dairy farm worker has contracted the highly pathogenic avian influenza (HPAI) A(H5) virus, commonly known as H5N1 bird flu. This marks the fourth human case in the United States linked to the ongoing outbreak among dairy cows and the first such case in Colorado, according to the Centers for Disease Control and Prevention.
The worker, who had been monitoring for symptoms due to exposure to infected cattle, reported only eye irritation. The individual received oseltamivir treatment and has since recovered. Previous cases were identified in Texas and Michigan.
the CDC emphasizes that this case does not alter its assessment of a low risk to the general public. Though, it reinforces the importance of taking precautions when exposed to infected animals. Those with close or prolonged, unprotected contact with infected birds, livestock, or contaminated environments face a higher risk of infection.
State health officials initially conducted testing, but results were inconclusive.Subsequent testing at the CDC confirmed the presence of influenza A(H5). The CDC is currently conducting genetic sequencing to determine the virus’s neuraminidase designation and to identify any changes that could affect the agency’s risk assessment.
The CDC detected this case through the state’s implementation of recommended monitoring and testing strategies. The agency has also taken several steps to enhance preparedness, including:
- Holding discussions with state and local health departments.
- Improving the supply of personal protective equipment (PPE) for farmworkers.
- Updating worker protection recommendations to include those working with dairy cows.
- Conducting outreach to farmworker groups.
- Initiating targeted digital outreach in affected counties to provide information on bird flu prevention.
The CDC recommends avoiding close, long, or unprotected exposures to sick or dead animals, including wild birds, poultry, and livestock. It also advises against unprotected contact with animal waste, bedding, unpasteurized milk, or materials that have been in contact with potentially infected animals.
What’s next
the CDC will continue monitoring influenza surveillance systems and conduct further analysis of the virus to assess any potential changes in risk. The agency urges individuals to follow recommended precautions to minimize their risk of infection with the H5N1 bird flu virus.
