China News Service, Zhengzhou, April 28 (Kan Li) In response to the recent discovery of a case of human infection with H3N8 avian influenza in Henan Province, an expert from the Infectious Disease Prevention and Control Institute of the Henan Provincial Center for Disease Control and Prevention said in an interview with a reporter from China News Service on the 28th that the The H3N8 avian influenza case is an isolated case, and no human-to-human transmission has been found so far.
China's National Health Commission reported on the 26th that a 4-year-old boy was found to be infected with the H3N8 avian influenza virus in Zhumadian City, Henan Province.
Henan Province carried out medical observation and sampling tests on the close contacts of the child, and no abnormality was found.
Experts' preliminary assessment believes that the H3N8 avian influenza virus is of avian origin and has not yet had the ability to effectively infect humans.
H3N8 virus has been detected in horses, dogs, birds and seals worldwide, but no human cases of H3N8 have been reported.
This outbreak is an occasional bird-to-human cross-species transmission, and the risk of large-scale transmission is low.
"After we received the report, we conducted health monitoring and nucleic acid testing (H3N8 avian influenza virus testing) on the co-exposed people and some close contacts. At present, no abnormal health conditions have been found in them, and the nucleic acid test results were also negative." Henan Province Li Yafei, a physician at the Center for Disease Control and Prevention, said that from the current monitoring situation, it should be a case, and no human-to-human transmission has been found for the time being, and the public does not need to panic too much.
"Under normal circumstances, people will not be infected with bird flu." Li Yafei explained, but in some special cases, bird flu virus will occasionally break through the boundaries of species, causing human infection and disease.
From the perspective of clinical symptoms, it is difficult to distinguish between infection with avian influenza virus and other respiratory infectious diseases.
Li Yafei introduced that the H3N8 avian influenza case discovered in Henan this time also had fever at the beginning, and then coughed, fatigued and had difficulty breathing, which was not much different from the symptoms of other respiratory infectious diseases.
"If you have suspected symptoms, you should seek medical attention in time." Li Yafei reminded that the bird flu virus is more sensitive to ultraviolet rays and heat sources. During the daily disinfection process, using 75% alcohol for 5 minutes or more can completely kill the bird flu virus.
For the public, daily protection can reduce the risk of infection.
