Young frequently caught bird flu virus mutates yet
January 21, 2014 07:49:47 Source: Evening News
Shanghai doctor died only 31 years old, this year there are eight Zhejiang patients less than 50 years old
Experts said there is no evidence of human to human transmission, but still wary
Yesterday, Zhejiang add three cases of H7N9 avian influenza.
Up to now, since the start of the year, Zhejiang Province, has a total 26 cases of H7N9 confirmed cases of avian influenza, from January 8 to start new patients diagnosed each day.
Reporters Statistics found that H7N9 bird flu last year older, and this year has been dropping. These 26 cases of infection in 8 patients younger than 50 years old. The youngest only 20 years old. Yesterday Shanghai due to H7N9 bird flu death doctor, only 31 years old.
H7N9 bird flu tentacles young, because H7N9 virus mutates it? Relatively resistant to young people, why encounter the virus, also fall so fast?
Yesterday, the reporter interviewed the province disease control experts and clinicians, asking questions of concern to the general public again.
Why multiply the young patients
Young families do not lianzhouzhuan overtime
This year's bird flu confirmed in 26 patients, the reporter carefully divided about their ages: 20 to 29 years, 2; 30 to 39 years, 4; 40 to 49 years, 2; 50 to 59 years, 8 people; 60 to 69 years old, 5; 70 to 79 years old, 5 people. If you draw a line at 50 years old, young patients below 8 people; elderly patients above 18 people.
Overall, though, this year's H7N9 bird flu virus, and there is no special "preference" of young people, the proportion of infections of all ages, not particularly noticeable differences. But the young man must not be taken lightly, can not be considered independent of H7N9 avian influenza with their own, or they will be very dangerous.
Zhejiang University Hospital of Infectious Diseases Joseph Leung professor warned that young man looked at the body strong, but now to the end of the year, people with a lot of overtime, some "lianzhouzhuan" office workers, after fatigue, colds, but also easy for H7N9 avian influenza virus chances.
So Dr Leung advice: Do not carrying a young cold, be sure to pay attention to rest, drink plenty of water, so that the body's immune system to restore as soon as possible, so as to fight with the virus. If there is a continuous fever, it is best to go to hospital blood test, if not high leukocyte index, lung inflammation, and have had contact with poultry experience, the best retest H7N9 virus nucleic acid.
H7N9 virus could mutate it
There is no evidence of human to human transmission, but still wary
Young filed, Shanghai doctors infection cases occurred, and the doctors have not come into contact with poultry, should H7N9 bird flu virus is showing signs of mutation?
Yesterday, the reporter put the question thrown Professor Lu Hongzhou, deputy director of Shanghai Public Health Clinical Center.
Professor Lu Hongzhou said to now, there are no cases of extraordinary human transmission of avian influenza H7N9 occurred.
Late last year, Zhejiang Huzhou Wengxu there had been infected with H7N9 avian influenza have been confirmed cases, then, Li Lanjuan academician after consultation with relevant experts believe that between them are not mutually infected, there is no evidence of human to human transmission.
However, Professor Lu Hongzhou alert, H7N9 avian influenza virus from person to person in a limited capacity exists in theory, he repeatedly stressed that this feature has been recognized by the national authority of the experts. "The so-called limited human-to-human transmission capacity, is characterized by the level of gene sequencing of the virus up analysis." Professor Lu said.
It is reported that the gene sequence of H7N9 avian influenza virus has been announced. This is the last one from the Zhejiang University, State Key Laboratory diagnosis of infectious diseases hospital director Li Lanjuan academicians, isolated and uploaded to international genebanks.
Professor Lu Hongzhou yesterday told reporters that since the emergence since the H7N9 bird flu virus, one of the country's experts are most concerned about is the thing, there is no monitoring of H7N9 virus mutation key nodes occur.
In his view, the new H7N9 virus hemagglutinin protein, the 226th amino acid particularly critical amino acids of this site has the typical human influenza virus genetic characteristics. Professor Lu Hongzhou, once the site of mutation, meaning the virus and human respiratory epithelial cells are easily combined, people may greatly increase the chance of infection, which is the successor of the will of people.
"This change will come when nobody predicted, but vigilance is necessary." Professor Lu Hongzhou said.

According to Voice of China reported this year as of January 19, around 199 cases of confirmed H7N9 cases. Experts said that at present the virus is still no significant variation occurred. Currently H7N9 is still a sporadic, Zhejiang, Guangdong and other southern provinces relatively high.
Yesterday, Chinese Center for Disease Control has responded.
Epidemiology Center chief expert Professor Zeng Guang believe that the virus occurred in areas which have a certain chance; Feng Zijian, deputy director of the Centre stressed that three terms, H7N9 virus either from the epidemiology or virology, are currently found no significant variation.
These three aspects: one is the ability to communicate is not more easily transmitted from birds to humans, is not it easier person to person? This has not changed, with seeing the same situation last year; second is independent of the variation is not more powerful? Lead to more serious after the onset? Severe cases and deaths occur more of? This situation did not appear; third is to see there is no antiviral drug resistance mutation. It still is alkyl resistant class of drugs, the neuraminidase inhibitors of drug sensitive. In other words, three aspects are not concerned about the variability of new changes. (Reporter Rui)
