Faced with the grim A flow prevention and control of the situation, experts have warned, this time have to deal with rational, scientific prevention and control, should not have into errors.
Misunderstanding 1: As long as fever, cough, sore throat, get a stream may be 80%
Many people think that if he felt a fever, cough, sore throat, it is probably 80% got a flow, in fact this is not quite right. Chinese Center for Disease Control and Prevention Disease Control and Emergency Response Office FENG Zi-jian said that the above symptoms, only 30% of the probability was that the flu, which is 30% where is the probability of a stream of 80%. But even so, FENG Zi-jian also believe that we can not simply use 30% multiplied by 80% to calculate the amount of the current A flow of patients, because the accuracy of detection by the sampling time, sample quality, and many other factors. In a period of time, in the sampling and monitoring of the level of quality there are no major changes in circumstances, it can use this digital analysis epidemic trends, but can not use this formula to estimate the person entitled to how much influenza-like illness is influenza A H1N1 influenza probability .
Misunderstanding 2: A flow of vaccines delayed vaccination does not matter
At present, under the Ministry of Health required that all localities receive the vaccine must be completed within two weeks after vaccination. But there are a lot of people think that playing the vaccine will be effective immediately, as early as late inoculation vaccination does not matter. “It’s wrong.” Pharmaceutical and Biological Products, deputy director of the Wang Kwong said, and vaccination should be more than one week after the time to play a role. Chinese Center for Disease Control and Prevention Director of the Center LIANG immunization program has also called on people vaccinated as soon as possible, he said, is now a popular trend of flow is very fast, if not vaccinated, if people are infected Zaiqu after inoculation, the vaccine would not work at, and from this point of view, the state has attracted so much time, hard-produced vaccines, it wasted.
Misunderstanding 3: Low temperature is not conducive to virus survival
A few days ago the cold air strikes, many people think that as the temperature reduced, a flow of the virus is not easy to survive, and low temperature is conducive to kill the virus. FENG Zi-jian pointed out that there was no scientific basis for this argument. On the contrary, the virus in a cold environment could survive longer. Sudden drop in temperature will also increase people’s risk of other respiratory infections, triggering transmission of the merger. According to medical experience, the weather cools down will make people resistant to the respiratory tract, which is easy to autumn and winter flu pandemic one of the reasons. At the same time, the weather was cold cause people to reduce outdoor activities, indoor activity. If you then pay no attention to maintain good indoor ventilation, crowd density, will also provide an opportunity to influenza virus.
