Year after 21st Century Business Herald, H7N9 bird flu set off a wave of small climax. The indications of an increase in confirmed cases so far this year compared with last spring, but so far, still in sporadic cases, a qualitative change has not yet occurred.
February 10, the National Health and Family Planning Commission released data show that from January 1 to February 10 evening, nearly 200 cases of people infected with the new H7N9 avian influenza reported confirmed cases, exceeding last four months (March 31 to July 28) the sum of the number of confirmed cases (ie 134 cases). Which in January H7N9 bird flu infected 31 people.
"The experts judged that the current human infection with H7N9 avian flu epidemic characteristics did not change significantly, sporadic cases still dominated, monitoring found no virus mutation occurrence of public health, the spread of the virus from the birds to humans is still."姚宏文 National Health and Family Planning Commission spokesman said at a news conference on February 10 in.
Despite the news that the Institute of Microbiology before discovered H7N9 virus has mutated, but mainstream opinion research community believes, H7N9 currently only have limited interpersonal communication skills.
"'Limited human-to-human transmission', which is a more accurate description." Members of the Group of Health and Family Planning Commission to treat the flu, Professor Lu Hongzhou Feb. 11 to accept when 21st Century Business Herald reporter interviewed explained.
Lu Hongzhou opinion, disease duration, clinical manifestations, and about 34% of the mortality, the situation this year compared with last year, probably no different, "but this year the situation is not to say, because, in general, patients from the onset to death The average time is 21 days, and now there are many patients in the hospital, just the onset. "
Source Lock live bird markets
And 2013 is slightly different from the spring of this year's cases are highly concentrated in Zhejiang and Guangdong provinces. Zhejiang Province, Wei Planning Commission briefing on the 10th, as of February 10, 2014 in Zhejiang people infected with H7N9 bird flu has reached 80 cases.
Guangdong Province since August 2013, cases were reported in 61 cases, of which less than 20 days from January 22 to February 10, the number of onset from 26 cases to 61 cases; deaths increased from three cases 13 cases.
In contrast, the number of cases in Beijing and Shanghai markedly reduced. Beijing on February 5 this year, the evening before the first two cases of confirmed human infection with H7N9 avian influenza; Shanghai municipal government announced on January 23, this year Shanghai found eight cases of confirmed cases of human infection with H7N9 avian flu, which killed four cases .
H7N9 virus infection source is from where? Are human transmission may occur? H7N9 bird flu is caused by the possibility of an influenza pandemic? This is the number of cases outside the major issues of public concern.
Released from infections to see a considerable number of patients have had breeding, sale, slaughter, purchase history of exposure to live poultry. Jiangsu Two new cases as an example: The patient went Qinmou sick before buying chickens two farms, home cleaning after cooking slaughtered by the market; patients in a home-Huan chickens 6, illness ago to nearby farmers market shopping, there are live poultry stalls within the market.
According to the Guangdong provincial CDC expert analysis, currently in Guangdong Province reported a total of people infected with H 7N 9 cases of avian influenza, patients ranged in age from 2.5 years to 83 years, mean age was 48 years; onset mainly in the elderly population over 50 years old 51%, experts believe that this is more engaged with the domestic activities of the elderly, and often related to the live bird markets; whereas cases of children under the age of 10, a total of seven cases, of which 71% of the relevant class family from poultry.
"More than 80 percent of patients diagnosed before the onset of live birds or live poultry contact history of environmental pollution, which is the main source of infection and our lifestyle has not changed, so this is the root cause of cases will continue to occur." National Influenza Center Director Shu Yuelong February 10, said.
About whether the H7N9 virus may occur from person to person, after the news, the Chinese Academy of Microbiology has deciphered the two most worrisome H5N1 and H7N9 avian influenza virus propagation mechanism across species and found that H7N9 virus has mutated, beginning with limited interpersonal communication skills.
This statement citing the vice president of Chinese Academy of Sciences Beijing life science, research China CDC deputy 任高福 research team. The team September 5, 2013 published papers that some epidemic strains of H7N9 mutation has occurred in four key amino acid sites, and the ability to obtain a combination of human airway cells in the journal "Science."
"Limited human to human transmission," There are special conditions
"'Limited human-to-human transmission', which is a more accurate description." When Professor Lu Hongzhou Feb. 11 to accept the 21st Century Business Herald reporter interviewed explained that "limited human to human transmission" means, in the patient's condition critical comparison, sputum more time in contact with the patient very closely, do not take protective measures, may occur from person to person.
"At present, it is spread from birds to humans, the spread between people is not easy, this is a very good chance we control the bird flu epidemic." Said Lu Hongzhou, but if we do not control the live bird markets, so that the virus sporadic infection, then after some time, it may become easily transmitted between people up.
Lu Hongzhou has been involved in several cases this year, Shanghai's consultation, including the January 18 morning after rescue 31-year-old surnamed Zhang died of medical personnel, "within the scope of the patient's residence is live poultry, that place is the urban fringe , went live poultry farmers lug sell. "
During the spring of this year went to Lu Hongzhou visited a treatment of last successful H 7N 9 people infected with bird flu patients. "The rehabilitation of patients after the live bird markets have not been, and his backyard three trees were cut down to prevent nesting birds."
Lu Hongzhou that analysis, Guangdong, Zhejiang, a relatively large number of cases, while a small number of cases in Beijing and Shanghai, the key lies in whether to close the local live poultry markets. Shanghai has announced that from 2014 until January 31 to April 30 suspended live poultry trade. This appears to be an effective way to deal with Lu Hongzhou.
"It is now very clear, ." Lu Hongzhou believes that the host range of this virus is very wide, in addition to chickens, ducks, and pigs kind of (animal) it will spread if not controlled now live poultry market, there may be a virus will infect other animals or species, other animals or species may also be infected and then infect humans.
Previously, the University of Hong Kong, Professor Guan international joint research team led in May 2013 in the journal "Science" published research papers also confirmed, H7N9 virus can only infect ferrets, but the virus can be effectively through close contact between individuals ferrets spread, and can appear limited air droplets. H7N9 virus can also infect pigs, causing mild respiratory infection and pneumonia. After the evolution of this virus does not exclude, it may cause an influenza outbreak.
"To be sure, H7N9 avian influenza virus has been variability from person to person does not know will not happen, but as long as we live control live bird markets, making it unable to infect from person to person, and that the virus would not be This variation from person to person appeared. "Lu Hongzhou said.
