A human case of avian influenza has been confirmed in Italy, marking the first imported human infection of this type reported in Europe, according to the World Health Organization (WHO).

On March 21, 2026, the Italian International Health Regulations (IHR) focal point notified the WHO of the detection of an avian influenza A(H9) infection in an adult man who had recently returned from Senegal. The information was released by the WHO in an official statement, highlighting the significance of the event for global health monitoring systems.

Epidemiological investigations conducted by Italian health authorities suggest that the patient had no known direct exposure to infected poultry or contact with individuals showing similar symptoms before the onset of illness. This detail has raised attention among health experts, as most human cases of avian influenza are typically linked to contact with infected birds or contaminated environments.

Authorities in Italy have implemented containment and monitoring measures to prevent any possible spread of the virus. The WHO emphasized that, under the International Health Regulations, any human infection caused by a new influenza A subtype is considered a potential public health concern requiring close surveillance.

According to the WHO, most recorded human infections with avian influenza A(H9N2) have been associated with exposure to infected poultry. In general, such infections tend to cause mild clinical symptoms in humans, though continued monitoring is essential to assess any potential changes in the virus.
