A strain of bird flu that jumped to dairy cows and then farmworkers in the US this spring could become a global health risk – but the extent of the threat is unknown and officials in Europe and elsewhere could be caught unprepared if it escalates. The US cases are the latest upswell of a highly pathogenic avian influenza (H5N1) that has been circulating among migratory birds and mammals in recent years, mostly in Europe and the Americas. Since March, the strain has cropped up in 145 cattle herds in 12 US states and infected four dairy workers, all of whom went on to recover from their illnesse...

“There is reason for increased awareness but not for increased concern,” said Pamela Rendi-Wagner, director of the European Centre for Disease Prevention and Control (ECDC) in a statement, adding that it was important to stay alert and proactive as “this threat to human health should not be underestimated”. While several outbreaks of avian influenza have been detected on farms around the world - with recent reports coming from farms in the United States - transmission to humans is still rare and limited to those in close contact with infected animals and contaminated spaces. Avian influenza is...

There have now been four human cases of highly pathogenic avian influenza, known as bird flu, in the US linked to an outbreak among dairy cows. The US Centers for Disease Control and Prevention (CDC) reported that a dairy worker in the state of Colorado tested positive for the virus. Three other cases have been reported in the US since April, one in Texas and two in Michigan. The person reported eye symptoms, received an antiviral treatment, and recovered from the infection. The dairy worker was being monitored due to their proximity to bird flu-infected cattle. The infection "does not change ...

Why has bird flu killed millions of wild and domestic birds, touched seals and sea lions, mink farms, cats, dogs and others but hardly touched people? That's "a little bit of a head-scratcher,” although there are some likely explanations, said Richard Webby, a flu researcher at St. Jude Children’s Research Hospital in the US state of Tennessee. It could have to do with how infection occurs or because species have differences in the microscopic docking points that flu viruses need to take root and multiply in cells, experts say. But what keeps scientists awake at night is whether that situation...

Health authorities identified a third human case of bird flu in the US amid an outbreak in dairy cattle. The US Centers for Disease Control and Prevention (CDC) said this was the second human case of influenza A(H5N1) in the US state of Michigan. Another human case of bird flu was detected in Texas in April. All three cases concerned dairy workers "with exposure to infected cows, making this another instance of probable cow-to-person spread," the CDC said, with no indication that it has been transmitted between people. The most recent case was the first to have typical influenza symptoms, auth...

The US Food and Drug Administration (FDA) said on Tuesday that samples of pasteurised milk had tested positive for remnants of the bird flu virus that has infected dairy cows. The agency stressed that the material is inactivated and that the findings “do not represent actual virus that may be a risk to consumers". Officials added that they're continuing to study the issue. “To date, we have seen nothing that would change our assessment that the commercial milk supply is safe,” the FDA said in a statement. The announcement comes nearly a month after an avian influenza virus that has sickened mi...
