Timeline
Three dairies in central California detected the bird flu virus among their herds and have been quarantined, according to the California Department of Food and Agriculture. There have been no human bird flu cases related to the incident, and there is no threat to the milk and food supply.
The July bird flu outbreaks in two Colorado poultry facilities were the country’s first known human cluster of cases caused by poultry. Previous infections were isolated cases. There was no reported human-to-human transmission, according to a new report by the Centers for Disease Control and Prevention.
Three more human infections were confirmed in workers from a second Colorado poultry facility, bringing the country’s total case count to 14 since 2022, according to CDC data.
A new Nature study found bird flu spread among cows in the U.S., and the animals also spread the virus to cats and raccoons. This is one of the first studies confirming mammal-to-mammal bird flu transmission.
The CDC confirmed an additional two bird flu cases in poultry farm workers from the same facility in Colorado, bringing the country’s total human case count to 11.
Officials confirmed a fourth bird flu case in a poultry farm worker on the same Colorado farm from last week. A fifth suspected case is pending confirmation from the CDC. This brings the national number to nine since the first human cases were detected in the state in 2022, with eight of the cases reported this year.
Colorado authorities announced three workers in a commercial egg operation have presumptive positive cases of bird flu, bringing the state’s count of known human infections up to as high as five—and the national number to seven. None of the workers have been hospitalized, and they showed “common respiratory infection symptoms” and pink eye. It’s the first time multiple cases have been recorded at the same location.
Colorado health officials confirmed the state’s second human case of bird flu in a dairy farm worker who has since recovered and only had mild symptoms, reporting pink eye.
Finland said it plans to begin vaccinating vulnerable populations like farm workers against bird flu as early as next week using 10,000 vaccine series—each with two doses—acquired as part of a European Union deal with vaccine maker CSL Seqirus to provide up to 40 million vaccines to 15 countries.
The World Health Organization announced a four-year-old child in India was infected with H9N2 bird flu—a different flu strain from H5N1—but recovered after suffering from seizures, respiratory distress, fever, and abdominal cramps. H9N2 has infected around 100 people globally since 1998, and this is the second human case in India.
Dozens of cows infected with bird flu have either died or been slaughtered in Colorado, Ohio, Michigan, South Carolina, and Texas. This is unusual since cows cost more to slaughter, and around 90% usually make a full recovery, Reuters reported.
A new study examining the 2023 bird flu outbreak in South America that killed around 17,400 elephant seal pups and 24,000 sea lions found the disease spread between the animals in several countries. This is the first known case of transnational virus mammal-to-mammal bird flu transmission.
Another human case of bird flu has been detected in a dairy farm worker in Michigan, though the cases aren’t connected. This is the first person in the U.S. to report respiratory symptoms connected to bird flu, though their symptoms are “resolving,” according to the CDC.
A new study with mice suggests that drinking infected milk can spread the disease and that a certain type of pasteurization may not always be effective in killing the virus.
Michigan reported bird flu in a farmworker—the second U.S. case—though the person showed no symptoms and was only detected through routine testing, suggesting asymptomatic transmission. The state also found bird flu in a flock of turkeys, the first in the U.S., though no cases have been reported in other states.
The recent case of a dairy worker in Texas who contracted a mild infection from dairy cows has raised concerns about the transmission of bird flu from animals to humans. The worker, who has since recovered, only experienced a mild infection, but the incident has highlighted the potential risks associated with close contact with infected animals.
The Department of Agriculture has been monitoring the situation closely and implementing measures to prevent the spread of the disease. Testing of ground beef samples from grocery stores in states with cow outbreaks has been initiated to determine if the virus is present in meat products. Additionally, the USDA has issued warnings against consuming unpasteurized milk to prevent potential infection.
Despite the concerns, the Food and Drug Administration has confirmed that dairy products are still safe to consume. Testing of grocery store samples of products like infant formula, toddler milk, sour cream, and cottage cheese has shown no live traces of the bird flu virus, although some dead remnants were found in some food items.
The World Health Organization has emphasized that bird flu does not transmit easily from person to person and that most cases result from close contact with infected poultry. While human-to-human transmission of bird flu is rare, each case is thoroughly investigated to rule out this possibility. The recent case in Texas serves as a reminder of the importance of proper hygiene and precautions when handling animals to prevent the spread of infectious diseases. In 2022, the first reported case of a person contracting bird flu from infected poultry occurred in Colorado. Fortunately, the individual fully recovered from the disease. This incident raised concerns about the safety of consuming products like milk and meat that may be infected with the avian influenza virus.
When it comes to milk, the FDA advises against consuming raw, unpasteurized milk as it may carry the bird flu virus. However, pasteurized milk is considered safe for consumption as the heat treatment during pasteurization deactivates any virus remnants present in the milk.
Similarly, the CDC warns against eating raw meat or eggs from animals suspected of having bird flu. Properly cooked meat and eggs are safe to eat as cooking at the recommended temperatures kills any bacteria or viruses, including the bird flu virus.
Symptoms of bird flu in humans include fever, cough, headache, chills, and respiratory issues. However, laboratory testing is required for an accurate diagnosis. In terms of egg prices, the recent bird flu outbreaks have led to a decrease in production, causing an increase in prices.
Poultry farmers are advised to cull infected birds to prevent the spread of the virus, with the USDA providing compensation for the birds and eggs that need to be destroyed. The government has approved vaccines for the H5N1 strain of bird flu, but mass production would be required in the event of a human outbreak.
In conclusion, while the risk of contracting bird flu from consuming milk, meat, or eggs is low if these products are properly handled and cooked, it is essential to follow food safety guidelines to minimize any potential health risks. The United States Department of Agriculture (USDA) initiated trials on H5N1 animal-specific vaccines in 2023 in response to the devastating impact of bird flu on poultry and other animals. Since 2022, over 92 million chickens have been euthanized due to bird flu outbreaks in 48 states, while 57 dairy cow herds in nine states have tested positive for the virus. The CDC reported that wild migratory birds are the likely source of the cow infections, raising concerns about potential mutations that could facilitate human-to-human transmission.
Experts have expressed alarm over the spread of bird flu to mammals, including cases in walruses, dolphins, elephant seal pups, and sea lions. The American Medical Association has warned that the virus may be seeking new hosts, posing a threat to human health. In 2023, more than 10 human cases of bird flu were reported to the World Health Organization, highlighting the global impact of the disease on both animal and human populations.
In an unprecedented development, the WHO confirmed the first human death from H5N2, a new strain of bird flu never before seen in humans. The victim, a 59-year-old man in Mexico, had no known contact with infected poultry or animals, raising concerns about the potential for human-to-human transmission. The man’s pre-existing health conditions may have contributed to the severity of the infection, underscoring the importance of vigilance in monitoring and addressing bird flu outbreaks.
