China Confirms First Human Case Of Bird Flu Strain
A 41-year-old man was admitted to hospital with fever symptoms in the eastern city of Zhenjiang on April 28 and was diagnosed with H10N3 a month later, China’s National Health Commission (NHC) said in an online 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.”
It described H10N3 as low pathogenic — less likely to cause death or severe illness — in birds.
NHC said there had been no human cases of H10N3 previously reported in the world.
Several 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 H7N9 virus.
H7N9 has infected 1,668 people and claimed 616 lives since 2013, according to United Nations’ Food and Agriculture Organisation.
The new development comes after Russia in February said its scientists detected first case of transmission of H5N8 strain of avian flu to humans and has alerted World Health Organisation.
The virus was found in seven employees at a poultry farm in southern Russia, where outbreaks of H5N8 were reported in the bird population in December 2020, officials say.
Following recent avian flu outbreaks in Africa and Eurasia, head of China’s Centre for Disease Control and Prevention last week urged stricter surveillance in poultry farms, markets, and wild birds.
COVID-19 was first detected at a food and animal market in the central Chinese city of Wuhan in late 2019.
