First human case of H10N3 avian influenza

1 June, 2021

China's National Health Commission informed that the first case of human infection with the H10N3 strain of avian influenza from the country's eastern Jiangsu province has been reported. The patient, a 41-year-old man from Zhenjiang city, is currently in a stable condition and meets discharge standards. The man is from  the city of Zhenjiang in Jiangsu province on China's east-central coast. His symptoms—nausea and fever—began on Apr 23. He was admitted to an intensive care unit on Apr 28, and he is currently listed in stable condition.
An investigation found no clear history of exposure to poultry, and no H10N3 had been detected in local poultry. No related infections were found in any of the man's contacts. Genetic analysis found that the virus is avian in origin.
H10N3 is a low pathogenic or relatively less severe strain of the virus in poultry and the risk of it spreading on a large scale is very low. 
No other cases of human infection with H10N3 have previously been reported globally. H10N3 strain isn't very common and has previously been found in wild birds and waterfowl in Asia and a few parts of North America, but not in poultry.
