If they did, I missed it on the Google alerts on H5N1.
Bear in mind that bird to human vectors exist. So if person A in a rural household is infected with H5N1, AND so is person B a few days later, it does NOT ‘prove’ a human to human vector. Both could be avian to human.
A verified human to human vector on H5N1 would legitimately be BIG NEWS on the health care front. If you can find the report and post a link, that’d be great. Nothing I could find on the CDC sites.
