#H3N8 #bird #flu has never been detected in the United States in people.
However, H3N8 viruses of a different genetic lineage have been detected in U.S. wild birds and some mammals in the past.
In 2011, there was an outbreak of H3N8 viruses among harbor seals in New England that caused deaths in 162 seals.
In the United States, current bird flu preparedness and surveillance activities are largely focused on #H5N1 bird flu, which is widespread in U.S. wild birds and has caused extensive outbreaks in U.S. poultry, with sporadic spillover to some mammals.
The current risk to the U.S. general public from H5N1 bird flu viruses remains low at this time; however, it is important to remember that #risk #depends on #exposure.
People with more exposure might have a greater risk of infection.
#CDC has guidance for specific groups of people with exposure to poultry, including poultry workers and people responding to outbreaks of avian influenza A(H5N1) in poultry.
Additional information on protective actions around birds, including what to do if you find a dead bird, is available as well.
