Mark Zavadsky SYANGAN (Hong Kong), 6 July - RIA of news. The experts of entire peace attempt to guess the riddle of the spread of bird influenza in China, while the Chinese driver of truck, who infected himself by virus in the middle of June, it proceeds with correction.
According to the data of the Chinese OF THE MEDIA, that are referred to the doctors of hospital in Shen'chzhen' city in the south of the country, 24-summer patient on the surname Tsien reads, he writes and even it listens to music. Soon doctors plan to permit it to breathe independently - recent twenty days patient is connected to the apparatus for artificial respiration.
From be glad the recovery of patient one alarming circumstance prevents - no one, until now, knows, where and as infected himself Tsien, local authorities did not report about flashes H5N1 among the birds in the south of China in the recent two months.
"All countries are equal before the bird influenza" - is such the public position of international officials, who carry out the coordination of efforts for averting of pandemia 0 0N throughout the world. "Epidemic can begin in any country of peace. We cannot say that the probability of the beginning of global pandemia in one country is higher than in another", it stated RIA of news the chapter of the Asian-Pacific Ocean representation of the World Health Organization (WHO - WORLD HEALTH ORGANIZATION) To Shigeru Of Omi.
In the unofficial conversations the officials OF WHO - WORLD HEALTH ORGANIZATION are less diplomatic. "Situation in China causes very serious uneasiness", asserts another representative OF WHO - WORLD HEALTH ORGANIZATION, which requested not to indicate its name. From October of past year in China were noted more than 30 outbreaks of bird influenza among the birds, moreover the centers of infection appeared in the entire country - from the province Of Guandun at the south to the internal Mongolia on the north.
"Such impression, that the infection ferments inside China and periodically it bursts open in the form of abcesses in the different places" - says the collocutor RIA of news and he again emphasizes that he would not want so that its name would be mentioned in the context of such statements.
This official can be understood: in WHO - WORLD HEALTH ORGANIZATION and Chinese authorities thus the complex history of interrelations. In the beginning of 2003, during the flash of atypical pneumonia, Chinese authorities sufficiently for a long time attempted to hide the scales of calamity.
This is how situation it is described in the new book "SARS - as was stopped global pandemia", published BY WHO - WORLD HEALTH ORGANIZATION during June of this year: "When virus appeared in China, the system of public health OF C.P.R. - CHINESE PEOPLES' REPUBLIC was nedofinansirovana and the country was not ready to accurate response. China could not in time recognize epidemic, which allowed virus to be extended in the entire country, and then beyond its limits. WHO - WORLD HEALTH ORGANIZATION repeatedly requested Chinese authorities to grant access to information on the disease, including in the course of the impartial conversation between To Shigeru Of Omi and by the minister of public health OF C.P.R. - CHINESE PEOPLES' REPUBLIC during March 2003 in Hong Kong".
The officials OF WHO - WORLD HEALTH ORGANIZATION recognize that China will extract lessons from that experience and today considerably more willingly it proceeds with collaboration. However, questions to the Chinese authorities remain.
"The substantial part of the cases of infecting the man by bird influenza occurred in the regions, where it was not fixed the flashes of infection among the birds, we thus far do not know how this to explain, says the official representative of the Peking office OF WHO - WORLD HEALTH ORGANIZATION the cluster Of Vad'ya. - We do not assert that the Chinese authorities hide the flashes of infection among the birds, but we should somehow explain this strangeness".
In the opinion of gonkongkskikh experts, Chinese authorities are today sincerely interested in "dissipating of" the sources of infection at the early stage, problem in the fact that the local authorities are not always ready operationally to report about the new cases of infection. There are problems with the peasants, who fear the forced destruction of entire poultry and hide the facts of case from the controlling bodies.
Meanwhile according to the data of the study of the international group of scientists, this published in the beginning year in the prestige American periodical U.S. proceedings of the National Academy of Science, precisely, the southern regions of China are the source of all known until today outbreaks of bird influenza.
The large part of the models for a study was assembled in the national parks May po in Hong Kong and in Poyan lake in the province Of Tszyansi, which are considered as the main places of the wintering of migratory birds from entire Asia. In the opinion of scientists, the results of their study make it possible to unambiguously assert that all four of the "virus of family" - Z, V and W - in Indonesia, and the so-called type of the "Delta of the Mekong" in Vietnam, originate from one virus, revealed in ducks in the Chinese province Of Guandun in 1996.
For scientists was possible to trace the mechanism of the propagation of virus 0 0N throughout the world for the latter several years. According to their data, initially the virus appears in poultry at the south of China, then it is transferred to the migratory weft, which winter in Poyan lake on the southeast of China. The following "center of infection" becomes the province Of Tsinkhay [Qinghai], where the weft, capable of living with the bird influenza long time, "share" by virus with other migratory birds. Then virus applies to the West - into Kazakhstan, Russia, Mongolia, Turkey, Croatia and Rumania.
Another way of virus goes to southeastern Asia, where it is transferred both with the migratory birds and with the poultry, that is transported of one country into another, it is asserted in the report. Today almost all experts are agreeable with the fact that the virus of bird influenza already took root in the ecosystem of the south of China and to get rid of it practically impossibly.
"Since we find virus in different it is specific birds, it is possible to draw the conclusion that the bird influenza became the integral part of our ecosystem, notes the minister of public health of Hong Kong York Zhou. - The discussion dealing not only about Hong Kong, but also with entire south of China".
"This means that in the south of China was formed the ideal" launch pad "for mutation and development of virus. A question only in that, will be able it to use this possibility", conclude in the interview RIA of news well-known gonkongskiy expert on the infectious diseases, doctor Law the faults Of Lok.
