A 41-year-old man in China’s eastern province of Jiangsu was hospitalized on April 28 and was diagnosed with H10N3 on May 28.
A 41-year-old man in China’s eastern province of Jiangsu has been confirmed to be the first human case of infection with a rare form of bird flu known as H10N3, the National Health Commission (NHC) said in Beijing.
Many different types of bird flu are present in China and some can occasionally infect people, usually those working with poultry. There is no indication that H10N3 could spread easily to humans.
The man, a resident of Zhenjiang town, was admitted to the hospital on April 28 and was diagnosed with H10N3 on May 28, the health commission said on Tuesday. It did not provide details on how the man was infected.
His condition is stable and he is ready to be released. Investigating his close contacts found no other cases, according to the NHC.
No other cases of human infection with H10N3 have been reported worldwide, it added.
H10N3 is low pathogenic, meaning it causes less severe chicken disease and cannot cause a large rash, in addition to NHC.
Patient clarity ‘unknown’
The World Health Organization (WHO), in a response to the Reuters news agency in Geneva, said: “The origin of the patient’s exposure to the H10N3 virus is unknown at this time and there are no other cases. seen in emergency surveillance among the local population.At this hour, there was no sign of human-to-human transmission.
“As long as avian influenza viruses spread in poultry, sporadic avian influenza infection in humans is not uncommon, which is a clear reminder that the threat of an influenza pandemic continues,” the WHO added. .
The filter is “not a common virus”, said Filip Claes, regional laboratory coordinator at the Food and Agriculture Organization’s Emergency Center for Transboundary Animal Diseases at the regional office for Asia and the Pacific.
Nearly 160 isolates of the virus have been reported in the 40 years to 2018, mostly in wild birds or birdfowl in Asia and some limited parts of North America, and none have been found in poultry. to date, he added.
China reports a possible first humanitarian case of # H10N3 bird flu, the National Health Commission (NHC) of China on Tuesday, in a hospitalized 41-year-old man.

Analysis of the genetic data of the virus is necessary to determine if it is similar to older viruses or if it is a novel mixture of different viruses, according to Claes.
The last human bird flu epidemic in China occurred at the end of 2016 and continued until 2017 with the H7N9 virus.
H7N9 has infected 1,668 people and claimed 616 lives since 2013, according to the United Nations ’Food and Agriculture Organization.
In the wake of recent avian flu outbreaks in Africa and Eurasia, the head of China’s Center for Disease Control and Prevention last week called for stricter surveillance of poultry farms, markets and wild birds.
COVID-19 was first spotted in the food and animal market in China’s central city of Wuhan at the end of 2019.
