Original title: Academician denial 'H7N9 virus then 1 bits are transmitted by person'
, 'two gene variations would be more effective at spreading, and this infection is currently just for the birds-to-human transmission.
fellow of the Chinese Academy of engineering, said Li Lanjuan yesterday categorically denied that H7N9 virus mutation will result in 'person-to-person'. Will happen the person-to-person transmission of the virus, said she is not sure can't deny that need further research and monitoring. '
yesterday has media reported said, China engineering homes academician, and national David Planning Commission infectious diseases focus Lab Director Li Lanjuan of team latest research indicates that, people infection H7N9 virus infection source has confirmed for chicken, poultry, and let people most concern and concerns of' people descendants 'suspense also has has clues: virus of gene as one rotating stairs, currently has found which 3 a' stairs 'of location occurred has changes, if again has a' stairs 'shift, on will damage' stairs 'of stability, Then the virus will cause 'person-to-person'.
since then, with 'Fellows H7N9 virus gene-3 shift, then a person-to-person' message spread rapidly.
yesterday, in an interview with CCTV's Li Lanjuan, said, if the two gene variations would be more effective at spreading, and this infection is currently just for the birds-to-human transmission, categorically denied that she say that 'person-to-person'. Will happen the person-to-person transmission of the virus, not sure it cannot be denied that need further research and monitoring.
locking the source of infection, 'bird' got the DNA evidence
'Yangtze River Delta' H7N9 cases detected since the Government shut down the live bird market on the one hand, many farmers ' markets don't see chickens and ducks, they can't eat, on the other, near 40% diagnosed patients but couldn't find the epidemiological history of contact with chickens and ducks, chicken, duck and if H7N9 infection? This article is at the international level for the first time brought out the evidence: H7N9 virus is spread from birds to humans.
academician Li Lanjuan, said our H7N9 isolated in patients with the virus, with live bird market chicken genetics H7N9 strain isolated in comparison, the study found, gene sequence is very close between the strains, homology over 99.4%.
monitoring and person-to-person to find effective methods of
H7N9 virus 2011 Korea Mallard isolated finds. In March this year, from birds 'jump' to mammals and humans, H7N9 does virus come and go between mammals, causes proliferation of interpersonal communication?
written by Zhejiang University stated: like other viruses, H7N9 has its unique genetic sequences. If H7N9 virus gene sequence to a long staircase, different genes and loci, as is one of the steps and their positioning.
the study found 4 of these 'steps' and positioning is the key. Studies have found that 2 amino acids in the H7 gene loci has occurred 'shift', equivalent to 2 steps have changed, which means that the virus affinity with human airway epithelial cells increased, so this spring, easy H7N9 from poultry to people.
currently, the research team has found the 1 point mutation, is to be on high alert, if this variation of 2 amino acid sites at the same time, will enable the virus effectively disseminated to the people.
'this possibility in? 'The reporter asked. said Li Lanjuan, H5N1 and other swine flu viruses in the past, there was no variation. However, later does not mean it is impossible, therefore need to be closely watched.
H7N9 virus 'lungs' also found a
clinical study also found that H7N9 avian flu symptom of people living with HIV are similar to H5N1 avian flu, among people with symptoms such as high fever and breathing difficulties, followed by 3-14 of respiratory failure within days.
in other words, H7N9 virus indeed 'lungs'. Due to have new revelations in the study. The researchers found that patients with severe infections prevalent in the 'cytokine storm' phenomenon, which causes the lungs to be substantial erosion of the virus. After you find the cause, researchers in clinical treatment in the creative application of artificial liver technology, to clear the inflammation, inhibit inflammation and avoid a massive 'cytokine storm', helps patients weather the difficulties of organ failure, thereby lowering the fatality rate.
