Excerpt:
The virus, experts are now concerned that the avian flu, including my own in many countries and regions have a long time. World Health Organization has recently announced an outbreak of bird flu in Egypt were reported. With the Influenza A H1N1 influenza pandemic, the body can easily become the new virus, "assembly plant." Avian influenza virus influenza A H1N1 influenza virus with the mixing, hybrid? Guan Yi said: "We do not know. But not because it is a low probability event, be regarded as not happen."
Guan Yi intuitively that from December 2009 to February 2010, coincided with Chinese New Year around the weather is cold, the use of poultry, large turnover, the avian flu virus in the environment, and stable, but so far have not heard of the domestic touching an infected bird cases of H5N1 reported, this is not a good thing.
Dr. Guan's research team found that: lead three times in the last century, the most serious pandemic influenza virus, before the advent of the disaster are close to complete in the form of communication for several years. 1918 H1N1 pandemic virus, today's seasonal H1N1 viruses and influenza A H1N1 virus may have already been together on the 1918-1919 inter-spread. Although these three kinds of different but related viruses. 1919 virus genes may be from 1911 onwards, in pigs and spread among humans, and that the virus can not spread directly from birds to people. The virus directly from birds to humans and cause a flu pandemic is very difficult, which may explain why the H5N1 virus has so far not caused a pandemic causes. 1957 H2N2 and 1968 H3N2 viruses have similar manner to form.
In the influenza issue, due to lack of continuous data since these periods, pigs with the pandemic virus, arising from such correlation can not be excluded. He suggested that China establish a special public relations group, very open way to explore the existing ecological environment in China, the virus the possibility of genetic recombination. He told reporters: "We should normally, conventional way to look at this issue, neither the disease Do not be afraid, do not conceal, otherwise, negative not only for the people, the State will be sapped."

Si-Dong Xiong pointed out that from a well-documented history of 2000 years of influenza, influenza pandemic did show some seasonal characteristics. Epidemic peaks occurred mainly in winter and spring, as the two seasons relatively dry air, ultraviolet weak environment for people living mostly closed for the virus to survive. However, air temperature, local micro-climate, and changes in the living environment of local people are likely to change the characteristics of influenza pandemic. In recent years, with the accelerated pace of globalization and air-conditioning and other facilities in the post-industrial age technology to improve people's living environment has become increasingly similar throughout the year, seasonal became blurred, as does the resultant gradient so that the virus of influenza throughout the year The onset of the rising trend.
From the time of seasonal influenza pandemic in an expanded view of the trend, in fact, belong to influenza A H1N1 flu seasonal influenza. In addition to seasonal influenza spread faster than the outside its current mortality and infection rates were still present close to the characteristics of seasonal influenza and seasonal influenza is not very clear boundaries. Proceeding from this, he reminded: In the past people think the summer is not a multiple of infectious diseases respiratory season now, with the influenza epidemic season changes, the 2010 Shanghai World Expo will be experienced in the summer should also be vigilant. "The world is all about influenza when it will happen, will have what kind of scale, as well as strains which have arisen in the monitoring system, but has never been accurately predict the number of years too. Like weather forecasting, as short-impending difficulties." He sighed Road.
