On Mar. 29, 2024, the U.S. Centers for Disease Control and Prevention (CDC) reported an infection with an influenza A(H1N2) variant (v) virus occurred in a child living near a pig farm in Pennsylvania who had direct contact with pigs prior to illness onset.

The person was hospitalized and has since recovered from their illness. CDC recommends that people in contact with pigs take precautions and provides specific guidance for people who are at higher risk of developing serious complications from flu.

The patient sought health care during the week ending March 9, 2024, and had the following symptoms: fever, vomiting, cough, and rhinorrhea (runny nose). The hospitalized patient received influenza antiviral treatment and recovered.

The case was first reported by the Pennsylvania Department of Health. Local public health officials found that the patient had swine contact prior to illness onset. No person-to-person spread of the A(H1N2)v virus associated with this patient has been identified.

Additional investigation determined that two of the patient’s close contacts had also contact with swine and had been ill before the patient developed symptoms. The two persons had mild illness; their symptoms resolved, and they were not tested for influenza.
