As US marks first H5N1 bird flu death, WHO and CDC say risk remains low
The H5N1 bird flu situation in the US seems more fraught than ever this week as the virus continues to spread swiftly in dairy cattle and birds while sporadically jumping to humans.
On Monday, officials in Louisiana announced that the person who had developed the country's first severe H5N1 infection had died of the infection, marking the country's first H5N1 death. Meanwhile, with no signs of H5N1 slowing, seasonal flu is skyrocketing, raising anxiety that the different flu viruses could mingle, swap genetic elements, and generate a yet more dangerous virus strain.
But, despite the seemingly fever-pitch of viral activity and fears, a representative for the World Health Organization today noted that risk to the general population remains low—as long as one critical factor remains absent: person-to-person spread.
"We are concerned, of course, but we look at the risk to the general population and, as I said, it still remains low," WHO spokesperson Margaret Harris told reporters at a Geneva press briefing Tuesday in response to questions related to the US death. In terms of updating risk assessments, you have to look at how the virus behaved in that patient and if it jumped from one person to another person, which it didn't, Harris explained. "At the moment, we're not seeing behavior that's changing our risk assessment," she added.
