Cows queuing for their midway milking at United Dreams Dairy, in North Freedom, Wisconsin on May 8, 2024.Matthew Ludak—The Washington Post/Getty Images  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Updated: Jan 19, 2026 2:22 PM UTCPublished: May 30, 2024 6:41 PM UTC A third dairy worker in the U.S. has tested positive for the bird flu infection that is causing outbreaks in cattle in at least [nine states](https://www.aphis.usda.gov/livestock-poultry-disease/avian/avian-influenza/hpai-detections/livestock). The farmworker, from Michigan, was exposed to infected cows and is the [first of the three recently confirmed cases to have respiratory symptoms](https://www.michigan.gov/mdhhs/inside-mdhhs/newsroom/2024/05/30/h5n1-updates), according to the Michigan Department of Health and Human Services. The previous two people—another in Michigan and one in Texas—did not show any respiratory symptoms but experienced discharge from the eyes. The dairy worker in the latest case worked on a different farm in Michigan than the previous case reported in the state. According to the U.S. Centers for Disease Control and Prevention (CDC), the dairy worker in the latest case also [experienced “watery discharge” from the eyes](https://www.cdc.gov/media/releases/2024/p0530-h5-human-case-michigan.html), but also reported coughing (with no fever). Tests on samples from the patient performed by Michigan's health department were positive for influenza A(H5), the avian influenza strain. Further tests conducted by CDC scientists confirmed the results. It's not clear whether the respiratory symptoms indicate that the virus is changing; CDC scientists are conducting additional sequencing studies to determine if that's the case. The CDC says there are no spikes in influenza cases among people in areas where the virus has been reported in cows, nor are there any unusual increases in emergency room visits or positive lab tests for influenza. So far, there have also been no reports that the virus was spread from one person to another in the infected workers’ households. In all three cases, the infected workers, as well as their families, were monitored and offered antiviral medications. The state of Michigan is continuing to work with farms to monitor for sick animals and symptoms in farmworkers and has tested 45 people so far, says Dr. Natasha Bagdasarian, chief medical executive at the Michigan Department of Health and Human Services. For now, the CDC says the outbreak in cows does not pose a significant health threat to people who don’t routinely work with the animals. Those who do, however, should wear protective equipment and practice caution when handling sick or dead animals, including birds and cows, as well as monitor and report any flu-likesymptoms to their local health department. In the first Michigan case, the farmworker was directed exposed to contaminated milk that splashed in his eye, and he was not wearing any protective equipment. In the latest case, the worker was not wearing a mask and worked directly with a sick animal, says Bagdasarian. "Two points to take home are that so far, people who are at risk are those who have direct, sustained exposure to sick animals, and second, that neither was wearing full personal protective equipment," she says. "So right now the risk to the general public is very low. There are no secondary cases of infections from these individuals, no sustained human-to-human transmission, and no cases outside of dairy workers." Still, there are things that everyone else can do to protect themselves. Avoid raw milk, which has not been pasteurized, the CDC advises. The temperatures required for pasteurization generally inactivate the virus, so pasteurized milk remains safe to drink, according to the agency. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6983927/bird-flu-outbreak-person-infected/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6983927/bird-flu-outbreak-person-infected/"},"headline":"A Third Person in the U.S. Has Bird Flu.
