The patient, a 41-year-old man from Zhenjiang city, is currently in a stable condition and meets discharge standards, the state-run CGTN TV reported.
Chinese health authorities played down the birdflu outbreak, saying the case was a sporadic virus transmission from poultry to humans, and the risk of causing a pandemic was extremely low.
The patient was diagnosed as having the H10N3 avian influenza virus on 28 May, the National Health Commission said in a statement without elaborating on how the man had got infected with the virus.
The man was stable and ready to be discharged from hospital. Medical observation of his close contacts had not found any other cases.
No other cases of human infection with H10N3 have previously been reported globally, it said. 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.
There are many different strains of avian influenza in China and some sporadically infect people, generally those working with poultry.
In April, a highly pathogenic H5N6 avian flu was found in wild birds in northeast China’s Shenyang city.
Many different strains of avian influenza are present in China and some sporadically infect people, usually those working with poultry. There have been no significant numbers of human infections with bird flu since the H7N9 strain killed around 300 people during 2016-2017.
No other cases of human infection with H10N3 have previously been reported globally, the NHC said.
