A 41-year-old man in eastern China’s Jiangsu Province was hospitalized on April 28 and was diagnosed with H10N3 on May 28.
A 41-year-old man in the eastern province of Jiangsu, China, has been confirmed as the first human case of infection with a rare strain of bird flu known as H10N3, according to the National Health Commission (NHC). ) from Beijing.
There are many different strains of bird flu in China and some occasionally infect people, usually those who work with poultry. There is no evidence that H10N3 can spread easily in humans.
The man, a resident of Zhenjiang City, was admitted to hospital on April 28 and diagnosed with H10N3 on May 28, the health commission reported on Tuesday. No details were given on how the man became infected.
His condition is now stable and he is ready to be discharged. The investigation of his close contacts found no other case, the NHC said.
No other cases of human H10N3 infection worldwide have been reported, he added.
H10N3 is poorly pathogenic, meaning it causes relatively less serious disease in poultry and is unlikely to cause a large-scale outbreak, the NHC added.
Patient exposure is “unknown”
The World Health Organization (WHO), in a response to the Geneva-based Reuters news agency, said: “At this time the source of the patient’s exposure to the H10N3 virus is not known and they were not found. other cases in emergency surveillance among the local population.At this time, there are no signs of transmission between humans.
“As bird flu viruses circulate in poultry, sporadic bird flu infection in humans is not surprising, which is a vivid reminder that the threat of a flu pandemic is persistent,” he added. WHO.
The strain “is not a very common virus,” said Filip Claes, coordinator of the regional laboratory of the Emergency Center for Cross-Border Animal Diseases of the Food and Agriculture Organization at the regional office of Asia and the Pacific.
Only about 160 virus isolates were reported in the 40 years to 2018, mostly in wild birds or waterfowl in Asia and some limited areas of North America, and so far no chickens had been detected, he added.
China reports possibly the first human case in history # H10N3 bird flu, the National Health Commission of China (NHC) said on Tuesday in a 41-year-old man hospitalized.
No other cases of human H10N3 infection worldwide have been previously reported, according to the NHC.https://t.co/0uR2tWakK7

Analyzing the genetic data of the virus will be needed to determine if it looks like older viruses or if it is a new mixture of different viruses, Claes said.
The last human bird flu epidemic in China occurred in late 2016 and continued until 2017 with the H7N9 virus.
According to the Food and Agriculture Organization of the United Nations (UNHCR), H7N9 has infected 1,668 people and killed 616 since 2013.
Following recent bird flu outbreaks in Africa and Eurasia, the head of China’s Centers for Disease Control and Prevention last week called for tighter surveillance of 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.
