Avian Influenza cases continue to rise in US birds
Highly pathogenic avian influenza (HPAI) was detected in the United States in December of 2021. There are two strains (originally from Eurasia) being monitored, the EA H5 and EA H5N1. The CDC says there is very low risk to the public, but it is important to keep an eye out for any sudden changes. There is a concern for domestic flock workers, as well as wildlife rehabilitators. There are currently 36 states with confirmed wild bird flu cases.
Here is a frequently updated page from the USGS with map graphics.

Florida has not reported any domestic flock cases, but was among one of the first states to see wild HPAI cases, with Brevard County having the most confirmed cases to date. Commonly identified flu bird species included waterfowl, vultures, great horned owls, pelicans, federally protected bald eagles, and more in Florida.

There are currently over 1,000+ entries in the US.
As of May 16th, only one person has tested positive in the United States with the H5N1 virus. The Center for Disease Control and Prevention (CDC) says that the public risk is very low, but precautions must be taken for anyone working with poultry or wild or domestic birds. According to the United States Department of Agriculture (USDA), there are 318 flocks and 37.87 million domestic birds in 34 states affected by HPAI.

Some quick tips:
Avoid all sources of exposure to wild birds whenever possible.
If you are in direct contact with sick poultry, protective wear and proper disinfection is recommended, along with proper removal of any gloves or facemasks.
If you travel outside the US, the CDC recommends to avoid poultry farms or markets that may sell live poultry products.
Keep your domestic birds away from wild birds and practice proper sanitation.
