The World Health Organization (WHO) says increased surveillance is urgently required to better understand what’s behind a recent spike in human cases of H5N6 bird flu in mainland China.
Only 48 people have been infected with H5N6 bird flu since the first confirmed case in 2014, but a third of those were reported in mainland China during the past 3 months alone. Half of all cases were reported during the past 12 months.
“Wider geographical surveillance in the China affected areas and nearby areas is urgently required to better understand the risk and the recent increase of spill over to humans,” a WHO spokesperson told BNO News...
...“Currently available epidemiologic and virologic evidence suggest that A(H5N6) influenza viruses have not acquired the ability of sustained transmission among humans, thus the likelihood of human-to-human spread is low,” WHO said.
The spokesperson added: “Due to the constantly evolving nature of influenza viruses, WHO continues to stress the importance of global surveillance to detect virological, epidemiological and clinical changes associated with circulating influenza viruses that may affect human (or animal) health and timely virus and information sharing for risk assessment.”
A study published by China’s Center for Disease Control in September reported several mutations in two cases of H5N6 and described the spread of the virus as a “serious threat” to the poultry industry and human health...
