A(H7N9) bird flu case in US chicken farm

According to an official report from the United States Department of Agriculture (USDA), avian influenza caused by the H7N9 virus has been identified at a poultry farm in Mississippi, United States. The most recent prior occurrence was in 2017. Avian influenza A(H7N9), a subtype of the influenza virus previously detected in avian species, was first observed in China in March 2013, affecting both animals and humans. Since that time, numerous instances of infection have been documented in humans and birds. This virus can induce severe symptoms in humans, is transmissible from animals to humans, and exhibits a mortality rate of 39%. However, human-to-human transmission is considered unlikely, according to the World Health Organization (WHO).
