HANGZHOU, April 22 (Reporter Zhang Yue intended surplus call Tao) first appeared in the East China human infection with the H7N9 avian flu epidemic is still spreading. At 21 16, report the infection of H7N9 avian influenza first Pobai, to 102 cases, the death toll continues to rise to 20 cases, the epidemic is not optimistic.
But at the same time, there is good news came: So far, at least 13 people were cured.
22 morning, 41-year-old Zhang Huzhou patients cured. He is in the evening of 8 participating local live poultry culling infected. 17, he was diagnosed with H7N9 avian influenza patients admitted to designated hospitals in Zhejiang Province - Zhejiang Medical School spent the day and night.
Mr. Zhang Zhejiang Province cure H7N9 bird flu. In his four days in patients with severe Miss Jia recovered and been discharged under the careful treatment of the hospital, one of the few patients with severe discharged.
Accompanied by the accumulation of experience of treatment, not only of critically ill patients like Ms. Jia able to get timely and effective treatment successfully cured, patients with early detection rate has been significantly improved, the mortality rate was significantly lower than in the past.
However, the development of the epidemic is still more severe. Recently, the number of reported cases shows a growing trend. From 13 to 21 days, confirmed cases have doubled for a few days, the number of reported cases to double-digit growth.
Increase in the number at the same time, the epidemic westward the North expansion trend and family clusters of cases. 13, 2011, the City of Jiangsu, Zhejiang and Anhui, the Northeast epidemic from spreading to Beijing and Henan. Beijing confirmed cases, three cases of Henan, located in six provinces and cities in 32 prefecture-level area.
Shanghai and even family members have been confirmed as infected with the H7N9 avian influenza virus family clusters of cases, which has aroused great concern of senior Chinese and the medical community.
Feng Zijian, director of the Chinese Center for Disease Control Health Emergency Center, said that the Father and of the Son and of the three infections, co-exposure to poultry or contaminated environment, or with each other due to the infection, is still under investigation, there is no conclusion.
"Even a small number of cases of familial aggregation, does not mean that the virus has the ability to have effective human-to-human transmission," he cautioned that, at present there is no evidence that H7N9 continued infected, it's not just the judgment of the Chinese Center for Disease Control , is also the consensus of the international public health agencies and disease control institutions.
Every day to report the number of new cases at the same time, China's official media promptly inform the latest treatment and research progress of the outbreak. Some experts also promptly publish their views on the trend of the epidemic, and to put forward a workable suggestions and comments.
Studies have shown that birds as the main source of infection of people infected with the virus. After the outbreak, Shanghai, Jiangsu, Zhejiang and other places to take decisive culling of live poultry, to close the trading of live poultry stalls and other measures. Some of the birds of the city flower market trading is temporarily closed, pigeon flying, Zoo, sights poultry show was temporarily halted.
Some experts also put forward more suggestions. Zhejiang Agricultural Society, chairman of Zhaozong Ying said, in addition to farms and live animal markets are included in the official supervision of live poultry culling and close the transaction, the next phase of the government should be more focus on rural households backyard and souks transactions and other weak links, to prevent the spread of the disease.
Of course, the prevention and control of the epidemic is still facing many challenges, there are many blank in scientific research.
Migratory birds flying north is considered to be one of the possibilities that lead to the spread of the epidemic north. Hong-Xuan, head of the animal disease research group of the Institute of Zoology, Chinese Academy of Sciences said publicly that currently found in all cases of infection have occurred in the channel of the Chinese migratory birds from East Asia to Australia.
However, he said, is a coincidence or epidemic association, which requires the forestry sector to enhance detection, research departments to speed up scientific and experimental analysis. Once found conclusive evidence of association, as soon as possible countermeasures.
Another puzzling phenomenon: in about 40% of the patients, there is no history of exposure to poultry or poultry markets, no clinical symptoms carriers. "In addition to the respiratory tract and contact transmission, a considerable part of the cases the source of infection is not clear, some people simply do not come into contact with poultry, have never been to the farmer's market." Deputy director of the Center for Disease Control and Prevention of Disease Control and Prevention of Zhejiang Province long CHEN En-fu said.
The Chinese Academy of Engineering academician Zhong Nanshan said that the current global know very little about this new virus, no history of poultry exposure incidence "is still a mystery.
Even so, the performance of the Chinese government, still the public confidence. Horizon Research Consultancy Group, a survey showed that nearly 7% of the respondents in the measures taken by the Government's response to the H7N9 avian influenza satisfied, more than 90% of respondents believe that the government has the ability to control and deal with the occurrence of H7N9 avian influenza good.
