Professor Dirk Pfeiffer (Chair Professor of One Health) was one of the international experts consulted for the update of the qualitative risk assessment of Chinese-origin H7N9 avian influenza spread in poultry and human exposure which the Food and Agriculture Organization of the United Nations (FAO) has just published.

The current risk assessment concerns the H7N9 viruses that emerged in China as a cause of zoonotic disease in 2013. These are now referred to as A/Anhui/1/2013-l lineage (AH/13-lineage) H7N9 avian influenza viruses. It addresses questions such as the likelihood of an increase in the prevalence of AH/13-lineage H7N9 virus infections or outbreaks in poultry in previously affected areas of China, the likelihood of viruses spreading within China and from China to unaffected countries of South and South-east Asia and beyond, either through global trade in poultry and related products, the movement of travellers or through wild bird movements or migrations.
