    "Virus hunter" Guan Yi: SARS unlikely large outbreak

    Nanfang Daily: Recently, the Middle East, the United Kingdom and other places after another report the case of a new coronavirus. People are still asking, SARS will one day suddenly another vest scrapping back, you think it will do?

      Guan Yi: wildlife markets do not appear massive resurgence SARS virus even if the return is also sporadic infection. Large SARS outbreak is unlikely to happen again.

      But other coronaviruses, such as the Middle East as the epidemic may still come. Do not know its origin and route of transmission, and now has begun human-to-human transmission, the virus outbreak. I have begun to do the work in this area.

      Nanfang Daily: You witnessed in 1997 the first case of human infection with the H5N1 virus, these years have been in the study. What's the latest progress in research on the avian flu? Guizhou also appear human cases of avian influenza, the development of the virus, what prediction?

      Guan Yi: After more than a decade, the avian flu becomes seems more likely to infect humans. Some people think that definitely not human-to-human transmission of avian flu, this is a very dangerous idea.

    If this day, human-to-human transmission, then powerful than the SARS big 1000 times, because the type of avian flu has a high fatality rate. We attach importance to this trend from the national strategic level. I once wrote a report to the Prime Minister, presented from a strategic height to recognize the importance of the control of avian influenza.

      Nanfang Daily: avian flu, why you so obsessed?

      YG: I do avian flu since 1996, during which witnessed the 1997, 2001, 2002 Hong Kong outbreak investigation and control of avian flu. Like that outbreak in 2001, we started from February 16 in the live bird market H5N1 highly pathogenic avian influenza, from March to April, several sporadic cases detected, May 15 day, there has been an outbreak of avian flu. At that time, we immediately decided to cull all the birds on the market, so the year did not happen to any human infection of bird flu cases. Post hoc analysis showed that the outbreaks were caused by five H5N1 avian influenza virus variants.

      Variant of the H5N1 avian influenza virus quickly and a lot of that in 2006, we discovered the different regions of the avian flu is not the same. Between the decade from 1996 to 2006, the H5N1 avian flu virus has been produced at least 45 variants. Based on their gene sequencing, we can know the direction of propagation of these viruses.

      H5N1 avian influenza in China from 1996 to the present, has not been completely controlled, this is a highly pathogenic avian influenza outbreaks around the world continued the longest, indicating that there is still room for improvement in our work. Our laboratory and team lives in Hong Kong, it is very difficult to monitor the country's bird flu situation. I hope that the Mainland the virology counterparts, they are able to further establish a the perfect national network of monitoring system to step up monitoring of the epidemic.
