Avian Influenza A(H3N8)

摘要

On 27 March 2023, the National Health Commission of the People’s Republic of China notified WHO of one confirmed case of human infection with an avian influenza A(H3N8) virus. This is the third reported case of human infection with an avian influenza A(H3N8) virus; all three cases have been reported from China.

Epidemiological investigation and close contact tracing have been carried out. There have been no other cases found among close contacts of the infected individual.

Based on available information, it appears that this virus does not have the ability to spread easily from person to person, and therefore the risk of it spreading among humans at the national, regional, and international levels is considered to be low. However, due to the constantly evolving nature of influenza viruses, WHO stresses the importance of global surveillance to detect virological, epidemiological and clinical changes associated with circulating influenza viruses which may affect human (or animal) health.
