Post Reply - H2H-H5N1 spread in US

**This is a dynamic list. Details of the cases will be added.**

   DJ-Again-so far it is not fully understood how cattle/cow-to-cow spread of H5N1 is going. So it may not be that easy to conclude we do have human-to-human spread of H5N1. 
One needs to rule out other ways/sources.

2024

2022

United States - European strain - Male, 40, poultry worker, test confirmed on April, 27, mild case. Colorado

DJ, This is the official CDC confirmed cases list of H5N1 human spread in the US. So 10 cases confirmed in 2024-7 of them in Colorado.  The last 6 cases-all from Colorado-in poultry workers...the other 4 cattle infected (2 from Michigan, Texas and Colorado each 1)

Also spread in mammals-detection goes on-worldwide. 

SE Asia also did see several H5N1 cases this year-all linked to birds. 

For that matter the US may detect bird-mammal-human trajects. It may be that -on a limited scale-mammal-human infections also happen in other places. 

For the US it is likely mammal-human spread has been going on for over 3 months ? (Texas case reported april 1). 

The H5N1 virus did get enough time to mutate to humans...
