WHO Disease Outbreak News
On 21 March 2026, the National International Health Regulations (IHR) Focal Point for Italy notified the World Health Organization (WHO) of the identification of a human case of avian influenza A(H9) in an adult male returning from Senegal. Next generation sequencing confirmed Influenza A(H9N2). According to epidemiological investigations, the patient had no known history of exposure to poultry or any person with similar symptoms prior to the onset of symptoms. Authorities in Italy have implemented a series of measures aimed at monitoring, preventing and controlling the situation. According to the IHR (2005), a human infection caused by a novel influenza A virus subtype is an event that has the potential for high public health impact and must be notified to the WHO. This is the first imported human case of avian Influenza A(H9N2) reported in the European Region. Based on currently available information, WHO assesses the current risk to the general population posed by A(H9N2) viruses as low but continues to monitor these viruses and the situation globally.
