Advice for Travellers
Avian influenza virus (H7N9) infection is unusual in humans but appears to cause severe illness in those infected. Preventive measures are the same as those for highly pathogenic avian influenza virus (H5N1).
WHO is producing a weekly report on the number of reported confirmed human cases for influenza A(H7N9), giving the geographical location and cumulative number of cases reported per month.
The European Centre for Disease Prevention and Control (ECDC) also publishes a daily Epidemiological Update on avian influenza A(H7N9) virus in China.
