Descripción
The ability of the H7N9 HPAI virus to infect both humans and poultry raises concern about a possible influenza pandemic and international spread either due to poultry or through wild birds. With the aim to provide sound and up-to-date scientific information for decision-makers globally, a qualitative risk assessment was conducted addressing the potential spread of H7N9 HPAI to unaffected provinces of China, other countries in South-East Asia and beyond during the period May to September 2017, as well as human exposure in affected areas of China where H7N9 HPAI has been reported. Several pathways of virus incursion were considered. Risk assessment is a powerful tool for supporting decision makers and national veterinary authorities to take scientifically sound decision based on the risk-levels assigned. Consequences of H7N9 HPAI can impact livelihoods, food security and poverty in rural areas, extended to all actors involved in poultry value chains. The impact is exacerbated by the pub lic health risk related to this zoonotic virus.
