Sun spread of avian influenza H7N9 and H5N1 stronger than Injurious! New research shows University of Hong Kong, H7N9 avian influenza virus propagation speed geometrically increasing, virus attack human bronchial cells twenty-four hours after propagation speed 25 times faster than H5N1, seventy hours after a thousand times faster; virus on lung cells also have a similar situation, and specifically attack lung tissue cells responsible for regeneration, affecting the patient recovered after infection progress. Experts warning H7N9 contagious, be careful winter outbreak.
Since the outbreak of H7N9 in February this year, there have been one hundred thirty-four cases of human H7N9 infection, 43 people died. University of Hong Kong yesterday in the international scientific journal "Lancet Respiratory Medicine" published studies, the use of in vitro cultivation, including bronchus, lung, nasopharynx, tonsils and other human airway tissue, analysis of human H7N9 and H5N1 viruses, and to compare lethal. The results showed that, H7N9 can infect humans efficiently and extensive bronchial epithelial cells, the situation is similar with ○ 九年 swine flu, H5N1 viruses multiply faster rate than more geometrically increments.
