"This new crown pneumonia epidemic is a major public health emergency that has spread the fastest, has the widest range of infections, and is the most difficult to prevent and control in China since the founding of New China." China ’s top leader made this judgment on the 23rd .

This judgment was also approved by the China-World Health Organization Joint Expert Expedition Group on New Coronavirus Pneumonia. So, where is the "difficult" epidemic prevention in China's "hardest" history?

Difficult to control, cut off, and difficult to protect

Liang Wannian, the Chinese leader of the joint expert inspection team and the expert group leader of the National Health and Health Commission's New Crown Pneumonia Epidemic Disposal, pointed out on the 24th that in terms of the control of the source of infection, the cut off of the transmission route, and the protection of susceptible people, the establishment of the new China Compared with new infectious diseases and major public health emergencies since then, the epidemic is indeed the most difficult to control.

The first is "difficult to control." It is also a respiratory infectious disease. The epidemic is reminiscent of SARS (Severe Acute Respiratory Syndrome) in 2003. However, studies have shown that the transmission of new crown virus is higher than that of SARS virus. Liang Wannian said that almost all patients with SARS have a high fever and can be quickly identified to control the source of infection. The new crown virus has a great concealment, "not only mild, normal, severe, critically ill patients, but also asymptomatic infection."

Du Xueping, president of the General Practice Branch of the Chinese Medical Doctors Association, said in an interview with the China News Agency that asymptomatic infections increase the risk of the epidemic and make it harder to monitor and prevent the epidemic.

The second is "difficult to cut." The phenomenon of "false negatives" in nucleic acid testing is frequent, and special cases have occurred in which the incubation period is too long, or the throat swabs are negative and the stool specimens are positive, which shows the "cunning" of new crown virus.

Liang Wannian mentioned that the clinical manifestations of many patients are slow in the early stage and may suddenly change after one week. "Signs and symptoms are not proportional."

"This epidemic occurred around the Spring Festival, and large-scale population movements also made it difficult to prevent and control the epidemic." Du Xueping said that all provinces across the country have confirmed cases, which is rare in the history of infectious diseases.

The third is "difficult to protect." On the one hand, targeted drugs and vaccines have not yet been developed. On the other hand, the new pathogenic virus has strong pathogenicity to the elderly and patients with basic diseases, and the inadequate pre-planning and preparation have made the epidemic prevention and control more difficult.

Dr. Zhuo Jiatong, chief physician of the Guangxi Center for Disease Control and Prevention, told our reporter that nearly 80,000 people have been diagnosed and more than 2,000 have died. 31 provinces have initiated a first-level emergency response mechanism, and cities with 15 million people closed their cities for more than a month. The "most history" shows the "difficulty" of epidemic prevention. He believes that without vaccines and precise medicines, everything is being explored, and it also tests the level of medical staff and the management and scheduling ability of governments at all levels.

What are the implications of China's response to "difficulty"

In the face of various problems, the epidemic prevention measures adopted by China have changed the epidemic trajectory of the new crown virus, so that the new crown pneumonia has not constituted a global "pandemic". While the interviewed experts affirmed this, they were also thinking about how to “solve difficulties” in the future.

Zhuo Jiatong believes that unknown viruses are emerging endlessly. As long as primary-level medical staff finds that the disease has been transmitted from person to person, they should treat them as severe infectious diseases and take corresponding measures instead of waiting for the laboratory to analyze the virus and draw conclusions Measures.

"It is still a worldwide problem to find infectious diseases in the shortest time, and to stop the virus during the window of transmission." Zhuo Jiatong said that the difficult situation of the epidemic that has come through the country's efforts has not come easily, prompting us to reflect on it. As a disease control expert, he called for the reporting mechanism to become more sensitive, and suggested that more talents be able to go to the scene and go to the grassroots to solve problems.

Many experts have noticed that community prevention and control should have become the "first line of defense" for epidemic prevention and control, but from a practical point of view, the shortage of primary medical staff is still a "big problem".

Feng Zijian, deputy director of the Chinese Center for Disease Control and Prevention frankly said that the epidemic showed weak grassroots epidemic prevention. For example, in Wuhan, a large number of patients concentrated in large hospitals in the early stage. If the community medical ability is strong or the family doctor system is complete, it can reduce Overloading medical institutions will also avoid cross-infection in hospitals.

Du Xueping suggested that after the epidemic, consideration should be given to how to strengthen the talent building of medical institutions in various aspects, including township hospitals, urban and rural public medical and health centers, and public hospitals. She bluntly stated that despite the industry's many years of calling for the training of general practitioners in hospitals, the loss of talents at the grassroots level is obvious, and it is recommended to encourage GPs to stay at the grassroots level through incentives such as treatment and promotion, so that they can sound professional "warning whistle" at the beginning of the epidemic .
