The U.S. CDC reported on September 10, 2021, two new human infections with novel influenza A viruses were reported by Iowa. Neither of the individuals was hospitalized, and both have fully recovered from illness.

No human-to-human transmission has been identified associated with either case.

The investigation into the sources of infections showed that household members of one individual kept swine, and the other had direct contact with swine.

Nine human infections with a novel influenza A virus have been reported in the USA this season. All individuals had direct contact with swine, were on a property with swine present, or had a household member who had direct contact with swine before illness onset.

And no human-to-human transmission of variant influenza virus associated with any of the nine cases has been identified.

When an influenza virus that normally circulates in swine, but not people, is detected in a person, it is called a “variant influenza virus," says the CDC.

People can be infected with various influenza viruses circulating in animals, such as avian influenza (Bird Flu) virus subtypes A(H5N1) and A(H9N2) and swine influenza virus subtypes A(H1N1) and (H3N2).

Even though Bird Flu and Swine Flu zoonotic viruses are found in humans, the annual 'flu shot' does not prevent zoonotic influenza infections, says the U.S. CDC.
