The man, from Zhenjiang, was hospitalized on April 28 after developing a fever and other symptoms. He was diagnosed as having the H10N3 avian influenza virus a month later – though it was unclear how he became infected. H10N3 is a less severe strain of the virus in poultry. The potential of it spreading over a wide-reaching area was low, according to the NHC. The most well-known avian flu strain, H5N1, has a 60% mortality rate, but the U.S. has yet to report any infections among people, according to the Centers for Disease Control and Prevention.
Avian influenza viruses rarely infect people, the CDC added. Health officials have stated that poultry workers are most likely to get sick when working with infectious or dead animals.
