China Human Bird Flu News

According to the WHO, China Human bird flu News is known to cause serious illness in people of all ages and kill almost half of infected people. “The increasing trend towards human influenza virus infection has become a major public health issue that cannot be ignored,” the researchers warned – CDC.

The surge in bird flu infections in China this year is a concern for experts, saying that previously circulating strains could clearly change and become transmitted to humans.
China reported 21 human infections with the H5N6 subtype of bird flu to the World Health Organization (WHO) in 2021, but only 5 the previous year.

Much less than the hundreds of H7N9 infected people in 2017, but the infection is severe, many are seriously ill and at least 6 have died.
Thijs Kuiken, Professor of Comparative Pathology at the Erasmus University Medical Center in Rotterdam, said:
Most cases are in contact with poultry and no confirmed human-to-human transmission, WHO said in a statement on October 4, highlighting the increase in cases. Urgently, “We need to understand the risk and increase of spillover to people.

Since then, a 60-year-old woman has been hospitalized in Hunan Province on October 13 in a critical condition with H5N6 influenza. The Hong Kong government. Although human H5N6 cases have been reported, no H5N6 outbreaks have been reported in Chinese poultry since February 2020.

China Human Bird Flu News -CDC Reports

The outbreak of China Human Bird Flu News: China is the world’s largest producer of poultry and the top producer of ducks used as a reservoir for the influenza virus.
The Chinese Center for Disease Control and Prevention (CDC) was unable to comment on the outbreak of China Human Bird Flu News in human cases of H5N6. However, a study published on their website last month found that “increased genetic diversity and geographical distribution of H5N6 poses a serious threat to the poultry industry and human health.”

The avian influenza virus circulates continuously in poultry and wild birds, but rarely infects humans. However, the evolution of the virus, which increases as poultry populations increase, is a major problem as it can easily spread among people and turn into a virus that can cause a pandemic. The maximum number of H5N6 infections was in southwestern Sichuan, but cases have also been reported in neighboring Chongqing, Guangxi, Guangdong, Anhui, and Hunan provinces.


At least 10 were caused by a virus that is genetically very similar to the H5N8 virus that devastated poultry farms across Europe and killed wild birds in China last winter. This suggests that recent H5N6 infections in China may be a new subtype.
“This variant may be a little more contagious (for humans)” According to a September report by the Chinese CDC, four of the Sichuan cases raised poultry and came into contact with dead birds. Another person bought a duck at a live poultry market a week before the onset of symptoms.


China vaccinates poultry after the outbreak of China Human Bird Flu News, but the vaccine used last year only partially protects against new viruses, preventing large-scale outbreaks but maintaining virus circulation There is likely to be. Food and Agriculture Organization.
Agricultural and rural areas did not respond to requests for comment.


Backyard farms are common in China and many still prefer to buy live chickens on the market. Guilin, Guangxi Zhuang Autonomous Region, which suffered two human incidents in August, said last month that it would suspend live poultry trading in 13 urban markets and close it within a year.

Officials say three other people in mainland China tested positive for H5N6 bird flu. Experts have called for increased surveillance over the past few months in the face of an increasing number of human cases.
The Guangdong Health Commission said in a statement Thursday that a 52-year-old man in Dongguan was tested positive for H5N6 bird flu. “Patients are currently being treated at a dedicated hospital in Dongguan,” the committee said. Details of the man’s condition were not immediately revealed, and the Health Commission statement did not include details of how the man was infected. The risk of human-to-human transmission is considered low.

China Human Bird Flu News – WHO Reports


Another case was reported in Yongzhou City, Hunan Province, where a farmer was hospitalized in a critical condition. According to the World Health Organization (WHO), a 66-year-old man became ill in late September, and samples from backyard poultry were positive for bird flu (H5).
Another case involving a 58-year-old woman from Hunan was revealed by Chinese authorities at a WHO meeting in September, according to a new report from the authorities. The woman became ill on August 28, but the case has not been announced. No details have been released regarding her condition.

The 4,444 Chinese authorities provide limited information on cases of H5N6 avian influenza in humans, and it often takes weeks before the cases are publicly reported by WHO. Most cases are first reported to the Hong Kong Ministry of Health. The Hong Kong Ministry of Health closely monitors human cases.


Only 52 people have been infected with H5N6 bird flu since the first confirmed case in 2014, but 20 have been reported in the last 4 months and more than half of all cases have been reported this year alone.. According to the WHO, H5N6 bird flu is known to cause serious illness in people of all ages and kill almost half of infected people. There were no confirmed cases of human-to-human transmission, but a 61-year-old woman who tested positive in July denied contact with live poultry.

A study published in September by the China Centers for Disease Control and Prevention identified multiple mutations in two recent cases of H5N6 avian influenza. “The increasing trend towards human influenza virus infection has become a major public health issue that cannot be ignored,” the researchers warned.


Thijs Kuiken, a professor of comparative pathology at the Erasmus University Medical Center in Rotterdam, also expressed concern about the increase in the number of cases. According to Reuters, “This variant may be a little more contagious (for humans) and more people are infected because of the high prevalence of this virus in poultry today. There is a possibility. “


Earlier this month, a WHO spokesman said increased surveillance was “urgently needed” to better understand the increasing number of human cases. A spokeswoman added that the risk of human-to-human transmission is low because H5N6 has not acquired the ability to be transmitted between humans for a long period of time.


Meanwhile, a report from the European CDC expressed concern about the detection of the H5N6 virus using markers for adaptation to mammals. “Additional reports of events infecting mammals such as seals and foxes, and serum epidemiological evidence of infection with wild boar shows evolutionary processes, including the adaptation of mammals that may acquire the ability to infect humans. It’s possible, “said it in the report.
