China registered the world’s first human infection of the H10N3 bird flu strain on Tuesday, Medical Express reported.

A 41-year-old man, who was admitted to hospital with fever symptoms in the eastern city of Zhenjiang on April 28, has been confirmed as the world’s first case of human infection of the H10N3 bird flu strain, China’s National Health Commission (NHC) said in a statement.

“The risk of large-scale spread is extremely low,” the NHC said, adding that the man was in a stable condition and his close contacts had reported no “abnormalities.”

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 was very low, the NHC added.

The NHC said there had been no human cases of H10N3 previously reported in the world.

Many different strains of bird flu have been found among animals in China but mass outbreaks in humans are rare.

The last human epidemic of bird flu in China occurred in late 2016 to 2017, with the H7N9 virus.

The H7N9 has infected 1,668 people and claimed 616 lives since 2013, according to the United Nations’ Food and Agriculture Organization.
