A few days ago, the World Health Organization's influenza type H1N1 alert level rose to sixth from fifth-grade class. It is reported that the WHO this is the first time in 40 years the level of infectious diseases rose to the highest level of alert. International epidemic alert level to improve on our impact on the prevention and control work? Prevention and control measures will be adjusted?

prevention and control work has been the norm in our country, the program

the Ministry of Health and the World Health Organization recently held a joint prevention and control of influenza H1N1 Type A News conference, the Ministry of Health spokesman Mao Qun said, for the WHO to enhance the level of early warning, the Chinese government expressed its understanding of , support and cooperation. Insist on the implementation of China's "outside the block input, within the non-proliferation," the prevention and control strategy is effective, in line with national conditions, the overall prevention and control work has been incorporated into the normal track of and procedures.

WHO resident representative in韩卓or that circumstances in the sixth grade, WHO general recommendations, but also recommended that the specific circumstances of their own to adjust to these proposals. The overall suggestion is that at this level, the Government should closely monitor the progress of the pandemic, including the rise and fall of the level of understanding of the epidemic and found that the "Tamiflu", such as antiviral drug resistance may be to identify any possible virus prompted the mutation or abnormal reorganization case or disease and other outbreaks. In addition, health services can also monitor the operation of the system to ensure its continuous operation can, and make rapid adjustments.

at the same time, WHO also called for all countries based on the current domestic situation, the existing national influenza pandemic plans to be adjusted accordingly, to focus on pandemic preparations from stage to adjust the response to the pandemic phase. WHO encourages governments to focus on the H1N1 influenza diagnosis and treatment of patients, while strengthening the public education campaign, to provide them with accurate up-to-date relevant information on the epidemic.

or韩卓particular emphasis pandemic alert system only reflects the geographical scope of the spread of the virus, rather than the severity of the disease, so far, outside the North American cases are mild to moderate condition of .

has been unclear is the source of local infection cases

quarantine measures or control points to fine-tune

Mao said that the previous stage, China to strengthen quarantine measures to control points, for the timely detection of imported STD cases, effective control of the dissemination and spread of the epidemic has played a very important role. "According to WHO recommendations, combined with the experience of the previous work, we will port some of the work of quarantine strategies to assess and adjust."

According to the Experts revealed that the port quarantine measures to adjust one of the reasons is that China has been the source of infection is not clear when a particular case of the local community. Health Department of Guangdong Province, according to briefing, June 11, Guangdong Province Add report 4 cases of influenza type H1N1 confirmed cases, of which in Guangzhou report cases of college students川籍a home-grown case. The case is a college students in Guangzhou, June 1 train from Guangzhou to Chengdu. Successively during the period in Chengdu by bus, taxis, karaoke OK, to the North Station train, restaurants and other dining. 7 pm, the case by Chengdu - Guangzhou train arrived on the morning of the 9th Guangzhou East Railway Station, and then by bus back to the school. The early morning on the 10th there fever , has been treated in isolation before being diagnosed with Type A influenza H1N1 confirmed cases. With the cases of the same trip by train from Guangzhou, Chengdu, back to a female passenger, also 10, began to dry symptoms . Almost at the same time as a result of both the disease, the source of their infection, the expert is being checked, is still unclear.

investigate the sources of the virus, the epidemic prevention and control, as well as analysis of trends in the epidemic has an important role. In general, cases of unknown origin of infection prevention and control measures are often adjusted watershed. Take Japan for example, on May 18 of non-importation of the disease quickly in Japan and a large spread of volume of unknown origin cases, the Japanese government decided to focus on prevention and control of immigration and quarantine to prevent the infection moved to expand the focus from the previous human quarantine to strengthen the national prevention and control of the transfer.

It is reported that China's response to influenza A H1N1 influenza joint prevention and control work under the Committee of Experts mechanism has been concerned about the trend of the epidemic at home and abroad, the local cases of infection of unknown origin appears, the experts on whether or not to adjust the port quarantine measures had different points of view. One view is that cases of infection of unknown origin, may mean that the domestic source of infection has been in existence for many, to spend a lot on quarantine in the port has very little meaning, should concentrate on prevention and control focusing on the domestic. Another view was that the current border still insist on the importance of containment. On the one hand, in Canada, the United States, Australia, and other cases of more countries, a large number of Chinese students, if the ports to relax quarantine, domestic imported cases may be increasing geometrically. On the other hand, China's social resources and personnel situation, the ordinary people against the disease, the degree of understanding and mastering with Japan and other developed countries have a certain gap, coupled with the capacity of national health services large regional differences, urban-rural divide, and bring a large number of cases increase the impact can be fatal. After intense discussion and analysis, the experts determined that at this stage is still "outside the block input, within the non-proliferation" strategy, based on the epidemic, as the development of quarantine measures for the control points to adjust.

to reduce the second-generation cases, to prevent the spread of the community to strengthen the treatment of severe, changes in response to the epidemic

introduced, according to Mao, China's alpha H1N1 influenza epidemic through the development of three phases: the first phase on May 10 is the emergence of the first confirmed cases in China, followed by the importation of confirmed cases increased; the second phase is May 29, China's emergence from the imported cases caused by second-generation cases and the second generation of cases showing a growing trend; the third phase is the source of my infection is not clear when a particular case of the local community and lead to second-generation cases. From this we can determine, our cases appear sporadic and caused by the local communities continue to spread the risk is growing.

experts said that in order to "reduce the second-generation cases, to prevent the spread of the community to strengthen the treatment of severe, changes in response to the epidemic," as the goal, at this stage is the key to the epidemic prevention and control of grasping the prevention and control of the fatigue with the balance to fight a protracted war, targeted, scientific and effective. More than a month to prevent and control high-intensity operations, in addition to the current virus showed a moderate, and so many people have had a relaxed mood or fatigue, but the influenza virus "diligent variation, to come and go without a trace" of the characteristics requires us to, prevention and control measures can not relax. Must continue to be strengthened and improved, including cities, communities, schools, enterprises, and rural, including all areas, all levels of joint prevention and control mechanisms, in close contact with those who do a better job of tracking and medical observation, control and reduce the emergence of second-generation cases .
