Studies show that swine flu virus can be transmitted through ocular conjunctiva

February 2, the Hong Kong Daily reported that the swine flu has been rampant and the virus has taken root in Hong Kong.　　University of Hong Kong research found that, even at 33 degrees Celsius environment, can still be active in the human respiratory tract bronchial system, and the transmission of influenza virus more than the general seasonal flu, not only through the nasal cavity and mouth invasion of the human body, more can infect ocular conjunctiva invasion of the human body.　　The flu virus is pervasive, but the public is not willing to inject the vaccine, the Secretary for Food and Health, Chow, said that although the current swine flu epidemic is mild, but every week there are deaths, and 20% of them do not have any chronic disease or other high-risk factors, so the public should not be taken lightly and the high-risk　　A study conducted earlier by the Department of Microbiology and Pathology of the Hong Kong University of Li Ka-Shing Medical College on the comparison of the Influenza A (H1N1) virus and the seasonal and H3N2 influenza virus has been published in the latest issue of the Journal of American Pathology. The study pointed out that the virus and seasonal influenza virus in the respiratory tract replication capacity is similar, but once the environment in 33 degrees Celsius, the virus in the bronchial replication capacity is high; The study also noted that respiratory cells infected with a swine flu or seasonal swine flu virus do not appear to be excessively activated by cytokines,　　Unlike the outbreak of the avian influenza virus, the excessive activation of cytokines causes serious morbidity, which also explains why the majority of people infected with swine flu did not have a serious syndrome of avian influenza A "recruit". In addition to infection of the respiratory tract, the study also found that the flu virus than seasonal influenza H1N1 or H3N2 virus, more susceptible to ocular conjunctiva, and H3N2 virus does not infect through the eye.　　The researchers said the swine flu virus can be active at a temperature lower than the other virus, one way to infect the human body, citing the rapid spread of the virus in the community, calling on the public should wash their hands to reduce the chance of infection. The government has been urging high-risk groups to be vaccinated as soon as possible however, in the 3 days from Friday to yesterday, only 4,986 people were vaccinated against swine flu, 3,452 of them were outside the residential care homes, and the remaining 1,534 were injected into the HA, DH and private clinics, with an average of 511 injections a day.　　At present, 157,440 high-risk persons have been vaccinated in the territory. Hong Kong's previous winter flu peak in 2 March, the current Health Protection Center monitoring System has not found a rise in the number of influenza.　　Chow said that the flu peak delayed, whether the unknown is due to last summer's peak flu continued for 4 months, it is difficult to predict when the second wave of swine flu occurred, do not rule out the delay and more moderate lethality. In addition, the 91-year-old man admitted to Princess Margaret Hospital by a swine flu vaccine last month 12th, the CHP has confirmed that he contracted pneumonia, not Giba's syndrome, and that the patient was recovered and discharged from hospital in Saturday.
