Earlier this month, Colorado Governor Jared Polis declared a Disaster emergency not due to wildfires which are common within the Centennial State this time of 12 months, but due to an outbreak of bird flu at a industrial poultry farm in Weld County, north of Denver. Now, several employees on the egg farm, who were required to cull poultry in response to the spread of bird flu, have tested positive for the disease.
Five individuals are infected, in line with the Colorado Department of Public Health and Environment. Since Sunday, the Centers for Disease Control and Prevention (CDC) 4 of those cases were confirmed. None of the employees were hospitalized, Colorado officials said, noting that their mild symptoms included Conjunctivitis or conjunctivitisand symptoms consistent with a respiratory infection.
Colorado was already ground zero for animal-to-human transmission H5N1the present strain of bird flu circulating worldwide. In 2022, a Farm employees in Colorado Culled poultry tested positive. As of this month, no further transmissions from poultry to humans have been reported, in line with CDC records. As of April 1, 2024 4 employees on US dairy farms tested positive for bird flu after contact with cattle: two in Michigan, one in Texas and most recently one in Colorado.
If the presumptive positive test from the recent poultry outbreak in Colorado is confirmed, 10 people within the United States may have contracted bird flu from cattle or poultry. The CDC believes the chance of contracting H5N1 to most people is low, but individuals who work closely with infected birds and other animals remain at higher risk.
Infected wild birds can transmit the virus to poultry and other animals through feces, mucus and saliva. Bird flu has to this point infected greater than 99 million poultry in 48 states and greater than 150 dairy herds in 12 states. Modern industrial agriculture has created ideal conditions for the spread of the disease, so Edwin Michael, PhDEpidemiologist on the University of South Florida School of Public Health.
“Look at the density of animals on these farms – these are not natural environments,” Michael said previously Assets“So as soon as you [an infection]these things will spread very quickly among farm animals.”
Michael added: “We need to look at the way farming is done. That’s the trade-off: you want cheap meat and all that, but when you raise animals that way, you open the door to other things.”
CDC: No evidence of human-to-human transmission of bird flu
The general public is at low risk of contracting bird flu. This is just not only because direct contact with infected birds is unlikely, but additionally since the CDC has not documented human-to-human transmission.
Tests by the Food and Drug Administration and the U.S. Department of Agriculture have shown that the nation The industrial milk supply is securebecause pasteurization inactivates H5N1. Eggs and poultry are also secureso long as they’re cooked to an internal temperature of 165 degrees, the CDC says.
In April World Health Organization agreed with the CDC’s assessment that there is simply a minimal risk to the population, citing an absence of evidence that the virus has acquired mutations that will make it easier to transmit amongst humans. The agency stressed that sporadic bird flu infections in mammals and humans are normal and that additional cases in humans wouldn’t be unexpected. This suggestion has not yet been updated following the recent wave of infections in Colorado.
Preventing widespread infection amongst farm employees is vital to limiting the chances of a virus mutation, says Michael Osterholm, PhDDirector of the Center for Infectious Disease Research and Policy on the University of Minnesota.
“There is no evidence at this point that this poses an immediate threat to humans,” said Osterholm. Assets in May. “We have not yet observed any transmission to humans that would prove that this is the next pandemic virus. On the other hand, there could be a reassortment event or further mutations tomorrow.”
What are the symptoms of bird flu in humans?
People infected with bird flu show a big selection of symptoms, from pneumonia requiring hospitalization to no symptoms in any respect. The CDC lists these other possible signs of infection:
- Cough
- Redness of the eyes
- fatigue
- Fever or feeling feverish

- Muscle or limb pain
- Runny or stuffy nose
