Highly pathogenic A(H7N9) virus mutation does not change risk to humans

In February 2017, a new A(H7N9) virus — indicating high pathogenicity in poultry — was detected in three patients connected to Guangdong, China, as well as in environmental and poultry samples. This is an important development to be monitored, however, ECDC’s updated rapid risk assessment concluded that the risk of the disease spreading within Europe via humans is still considered low, as there is no evidence of sustained human-to-human transmission.
