This year is the first Spring Festival after China’s optimized prevention and control plan. Most of those who have not returned home for the New Year They all chose to go home for the New Year. According to estimates by relevant departments, during the Spring Festival this year, there will be about 5 billion tourists visiting relatives and friends. Everyone may be very concerned about the large flow of people and the new crown epidemic that is still in the epidemic stage.

1. During the Spring Festival and the recent epidemic

After optimizing the prevention and control plan, the new crown epidemic has spread rapidly across the country. At present, the country as a whole has passed the peak period of the epidemic, and the large, medium and small cities and counties in the country are basically in the stage of epidemic decline.
This wave of new crown epidemics in my country is mainly caused by multiple subtypes or evolutionary branches of the Omicron strain. Among them, the BA.5.2 strain has the absolute advantage, followed by the BF.7 strain, and the third is the BA.2.76 virus. strains, and the total proportion of more than ten other subtypes or evolutionary branches is less than 5%. The main epidemic strains in some provinces are also different. For example, the main epidemic strains in Beijing and Tianjin are BF.7.
Although a large number of people flow during the Spring Festival may promote the spread of the epidemic to a certain extent, and the number of infected people will increase in some areas, but because this wave of epidemic has already infected about 80% of the people in the country, in the short term, for example, in the next 2 -3 months, the possibility of a large-scale epidemic rebound or a second wave of epidemics across the country is very small.

2. Personal epidemic protection during the Spring Festival

People who were infected earlier, such as those who were infected in early December last year, and those who were infected in children, teenagers, and young adults have basically recovered. As for middle-aged and elderly infected people, there are still a certain proportion of them. Although the nucleic acid or antigen has turned negative for several weeks, they seem to have "recovered", but there are some symptoms, such as cough or dry cough, phlegm in the trachea, and a slight increase in body temperature in the afternoon. (referring to the ear temperature around 37.5C), wait, mile-mile-la-la lasts for more than a month or longer, and lasts until the Spring Festival.
People who are experiencing COVID-19 infection are not recommended to visit relatives and friends during the Spring Festival.
Those who have been infected with the new crown but still have persistent symptoms are advised to visit relatives and friends appropriately according to their physical condition.
Those middle-aged and elderly people who have been infected with the new crown seem to have "recovered and recovered", but their physical functions have not fully recovered to the state before the infection. It is not recommended to travel long distances or visit relatives and friends during the Spring Festival.
Most people who have recovered from infection have not fully recovered to their pre-infection state. When gathering with relatives and friends, do not act in the same state as before the infection, do not stay up late and work hard, and do not drink alcohol at the previous level.
Families with elderly people in the family, if the elderly have been infected, no matter whether they have persistent symptoms or not, they need to continue to closely observe the changes in the physical condition of the elderly. Once the symptoms recur or worsen, they should be sent to the hospital for medical treatment in time. If the elderly have no infected family, visits to relatives and friends must be strictly controlled, and necessary protection must be done to prevent the elderly from being infected.
People who have recovered from the new crown are all recently infected, and some are still in the process of recovery. The possibility of reinfection during the Spring Festival is relatively small, but a small number of people may also be reinfected.
Regardless of whether you have been infected or not, you need to take personal protection during your round-trip travel and in public places to prevent infection or re-infection, or to prevent infection with other respiratory infectious diseases.

3. Foreign novel coronavirus mutant strains 

The main strains currently prevalent in the United States are BQ.1, BQ.1.1 and XBB.1.5 mutant strains, of which XBB.1.5 strains accounted for the most popular strains in December last year and early January this year The proportion of the increase is relatively fast, which has attracted the attention of the United States and the world. Imported cases of this strain have also been detected in individual cities in my country, but this strain has not been detected in local infection cases. Although the XBB.1.5 mutant strain has been introduced, it is less likely to spread in my country in the short term and trigger a new wave of epidemics.
Recently, Thailand reported the detection of the new crown delta cron mutant strain (XAY.2), which has attracted widespread attention. In fact, Deltacron was detected in some European and African countries as early as a year ago. This mutant strain has not been detected in my country. Due to the small number of infected cases, there is still a lack of data on the transmission, pathogenicity and immune escape ability of this strain. It has been about a year since the mutant strain was first detected, and it has not spread globally. Judging from this, in the short term, the possibility of a new round of global COVID-19 epidemic caused by the deltacrion mutant strain is relatively small.
