Some relevant bits:
This new case does not seem to indicate human-to-human transmission of the highly pathogenic avian flu, as it was detected on a different farm from the previous Michigan case, officials said.
This is the first time in the US outbreak a person with H5N1 has displayed respiratory symptoms, unlike the previous two cases with only conjunctivitis, commonly known as “pink eye.” The respiratory symptoms are concerning because they “increase the odds of exposing someone to the virus as compared to conjunctival symptoms”
“To date, none of this individual’s close contacts have developed or reported any symptoms, and they have been offered Tamiflu,”
Officials have not “seen anything in our genetic analysis thus far to suggest changes to the virus that might make it more easily transmitted among humans”, Shah said.
