Cambridge University has published a research report on several varieties and transmission routes of COVID-19.
According to the report, COVID-19 is divided into three varieties: A, B and C, and Type A virus is more common among infected people in the United States and Australia. There are few class A cases in Wuhan, and they are from Americans who have lived in Wuhan. Class A is most similar to viruses extracted from bats and pangolins. Researchers refer to Class A virus as "the root of the outbreak" (? "That? Root? Yes? That? Outbreak " )。
Type B strain is the main type in China (Wuhan) and has not spread to East Asia.
Virus C is the main type in Europe. Hong Kong, Singapore and South Korea in Asia are all of this type. Can't find it in Chinese mainland.
Researchers believe that type C of Class A strains evolved from type B, and type B evolved from type A. ..
The research method used by researchers is mainly to track the population flow of prehistoric humans by studying DNA.

People entering Beijing should hold a negative health certificate of nucleic acid test within 7 days when staying in the hotel.
On April 10, at the press conference on epidemic prevention and control in novel coronavirus, Beijing, Zhou Weimin, a first-class inspector of Beijing Municipal Bureau of Culture and Tourism, said that at present, the epidemic prevention and control work in the capital has entered a normal state, and there is a great pressure on external defense investment and internal defense rebound. In order to make the epidemic prevention and control network more rigorous and firm, implement the requirement of "due inspection" and plug all loopholes that may lead to the rebound of the epidemic, it is decided to further strictly control the accommodation personnel in Beijing.
First, starting from April 12, people entering Beijing must hold a health certificate that the local nucleic acid test is negative within 7 days, and the national health pass code or Beijing Health Bao certification is "no abnormality". At the same time, it is necessary to register contacts in Beijing as required and accept hotel hygiene management.
Second, the hotel should strictly implement the responsibility of epidemic prevention and control, check the nucleic acid test health certificate provided by passengers and supervise them to fill in the check-in information truthfully, conduct temperature tests on passengers in the morning and evening and pay close attention to their health status.
Third, the public security departments should continue to increase the investigation and punishment of false information and nucleic acid testing health certificates, and severely crack down on illegal acts.
In the process of implementation, the above measures will be adjusted according to the development and changes of the epidemic.
The central government explicitly allows couriers to deliver goods in communities (villages).
The "Opinions" put forward that it is necessary to actively and orderly promote the resumption of work and production, including the resumption of production order by division and classification, the resumption of production in the whole industrial chain, and the resumption of production in the service industry.
In terms of restoring production order by division and classification, low-risk areas should change from emergency unconventional prevention and control to normal prevention and control, cancel prevention and control measures that are incompatible with normal production and living order in time, adjust work priorities and response measures according to the situation, and must not delay returning to work by means of approval and filing. Hubei Province, Beijing and other provinces where high-risk counties are located should take differentiated measures according to the situation of epidemic prevention and control in the local area to resume work in a safe and orderly manner.
In promoting the resumption of production in the whole industrial chain, the Opinions proposes to strengthen the protection of factors, help solve the problems of employment, capital, raw material supply and major projects in a timely manner, support core enterprises in the supply chain to drive upstream and downstream enterprises, especially small and medium-sized enterprises, to resume production, and ensure the production and export of enterprises and key products that have important influence in the global industrial chain. Do a good job in agricultural production and stable production and supply of important non-staple foods, and fully restore the operation of the farmers' market.
In promoting the resumption of service industry, operators in low-risk areas independently decide the time for the resumption of service industry. For cultural tourism, catering and places with closed space and concentrated personnel, the density of personnel shall be controlled by means of reservation, diversion and flow restriction. On the premise that prevention and control measures are in place, we will promote the resumption of work in various shopping malls and markets in an orderly manner. National cultural and sports activities and cross-provincial cross-border tourism will not be resumed for the time being. Improve the relevant prevention and control measures of logistics express delivery industry, and allow express delivery personnel to enter the community (village) for distribution.

According to the traffic management bureau, the office hours are 9:00- 16:00 on weekends. The peak hours of traffic violations are from 9: 00 to 1 1, 14 to 16.
