China News Service, Harbin, February 1 (Reporter Wang Nina) "This epidemic is different from the past. It has the characteristics of fast spreading and strong concealment. The epidemic situation in Heilongjiang Province will improve significantly in the next week to two weeks." Zhong Nanshan said. .

  On the morning of the 1st, Yang Baofeng, an academician of the Chinese Academy of Engineering and a professor of Harbin Medical University, and Zhong Nanshan, an academician of the Chinese Academy of Engineering, joined the video link to jointly "take the pulse" of the epidemic prevention and control work in Heilongjiang.

  At the connection site, Yang Baofeng said that in the severe cold seasons of the "March Nine" and "Forty Nine" in Northeast China, cluster infections of the new crown pneumonia epidemic appeared in some places, and the number of infections was very large, and prevention and control were very difficult.

Why did this epidemic occur in the north, especially in Wangkui County, a rural area in the northeast?

  Zhong Nanshan said: "This epidemic is different from the past. It has the characteristics of fast transmission and strong concealment. We have seen that this wave of epidemics not only broke out in the northeast, but also has a high transmission rate in Russia. This is related to the background of the spread of the virus. ."

  Zhong Nanshan analyzed that the sporadic cases in Heilongjiang were firstly affected by the climate. The winter climate in Northeast China is cold and long, which is suitable for the survival of the new coronavirus. The outdoor cold chain and indoor closed environment in the north are also conducive to the spread of the virus.

Secondly, rural areas are the weak link and difficulty of our national defense control, and people don't know much about defense knowledge.

In addition, before the Spring Festival is the peak of migrant workers returning to their hometowns. After they return home, they participate in ceremonies and visit relatives and friends, creating opportunities for the spread of the virus.

  Zhong Nanshan said: "At present, the trend of easing the epidemic in Heilongjiang is the result of the strong intervention of the Heilongjiang Provincial Party Committee and the Provincial Government." He said that in several places outside Wangkui, Suihua City, there has been no new crown for a week. The medical records of pneumonia confirmed, it can be said that Heilongjiang Province has done very well in prevention and control measures.

Recently, Lanzhou University has conducted a data forecast analysis. The results of the analysis show that if there is no strong intervention by the Heilongjiang Provincial Party Committee and the Provincial Government, according to the law of the spread of the new crown virus, by the end of February, 130,000 people in Heilongjiang Province should be infected with the new crown virus. .

  Does the easing of the epidemic mean that we can relax our vigilance?

In this regard, Zhong Nanshan said: "I have great expectations for Heilongjiang. The epidemic can be controlled. It is hard-won, and we must cherish it. I believe that under the leadership of the Heilongjiang Provincial Party Committee and the Provincial Government, everyone can have more patience in the future. The epidemic situation will improve significantly in one to two weeks."

  In response to people’s protection against the new coronavirus vaccine, academician Zhong Nanshan said that my country’s vaccines can withstand the test. According to the current situation, after vaccination with the new coronavirus vaccine, at least half a year has a good preventive effect.

He emphasized that whether the vaccine plays a protective role, it is very important to see how much it can prevent severe illness. So far, no one has said that the new crown vaccine that hit China has developed into a severe illness.

  Academician Zhong Nanshan reminded you to wear a mask even if you get the new crown vaccine.

The vaccines in our country are mainly whole virus inactivated vaccines, which are very safe.

Under normal circumstances, people will develop antibodies after the first dose of injection, and the protection level is about 60%-70%; 14 days after the second injection, the protection level can reach nearly 90%.

The vaccine may not be fully effective until about 35 days after the vaccine, but it cannot be prevented 100%, and there is still a risk of infection, so personal protection should be paid attention to.

  Yang Baofeng said that at present, the epidemic in Heilongjiang has eased, and now the Spring Festival is approaching. He asked Zhong Nanshan to give some good guidance on local prevention and control work and the people's epidemic prevention and life?

Zhong Nanshan emphasized that the new crown virus will coexist with people for a long time. Heilongjiang Province has many migrant workers. Under normal epidemic prevention and control, people should continue to take personal protection, wear masks, wash hands frequently, and ventilate frequently. If there is an epidemic, consciously report.

  Academician Yang Baofeng said: “In the cold weather like Heilongjiang, the staff prevent and control, sample, and inspect, and work continuously outdoors. It is very hard. Every one of us must cherish the current results of prevention and control. Under the epidemic, everyone is To be a protector, you must pay attention to diet diversification in home isolation, make good use of your personal time, do more exercises, etc. to improve your personal immunity."
