China Reports a Human Case of Rare H10N3 Bird Flu

A 41-year-old man in China’s japanese Jiangsu Province is the primary recognized human to be contaminated with a pressure of chicken flu referred to as H10N3, China’s National Health Commission mentioned on Tuesday — a improvement that consultants mentioned merited shut monitoring as a result of of an underlying continued threat of pandemic flus.

Avian viruses don’t sometimes unfold amongst people, however they’ll pose a hazard to people in the event that they combine with a human virus, mentioned Raina MacIntyre, the pinnacle of the biosecurity program on the Kirby Institute on the University of New South Wales in Australia.

“If someone has human flu and is infected with bird flu, the two viruses can swap genetic material,” she mentioned. “That’s why you see the concern for pandemic flu arising in countries where humans and livestock have very close contact.”

The Health Commission’s announcement mentioned that there was no proof of human-to-human transmission within the Jiangsu case. Contact tracing and surveillance haven’t uncovered every other infections, officers mentioned.

Influenza viruses differ from coronaviruses, and the World Health Organization is working with the Chinese authorities to observe the case, in response to a assertion from the W.H.O. division in Beijing.

The man started feeling feverish on the finish of April and was hospitalized on April 28, the Chinese authorities assertion mentioned. On May 28, genome sequencing by the Chinese Center for Disease Control and Prevention decided that he had been contaminated with H10N3.

The authorities announcement didn’t say how the person had been contaminated, and the W.H.O. mentioned the supply of an infection was nonetheless unknown. The man’s situation has stabilized, and he is able to be discharged, the federal government mentioned.

Professor MacIntyre mentioned that people who find themselves normally contaminated by avian viruses are those that are in extended shut contact with the birds, akin to poultry handlers.

The W.H.O. mentioned that H10N3 had “been detected periodically in birds in live bird markets as early as 2002,” however the virus is unlikely to kill birds or result in many indicators of sickness.

“As long as avian influenza viruses circulate in poultry,” the group mentioned, “sporadic infection of avian influenza in humans is not surprising, which is a vivid reminder that the threat of an influenza pandemic is persistent.”
