Asymptomatic infections increase

Why is there a recent trend of an increase in asymptomatic infections?

Wu Fan, a member of the Shanghai Municipal Public Health Expert Group on Epidemic Prevention and Control and vice president of the Shanghai Medical College of Fudan University, explained that in the context of the global epidemic trend, according to the latest statistical report of the World Health Organization, since November 2021, for two consecutive months, the number of new cases in the world has been rising and showing a rapid upward trend. In addition, the new Omilon variant has emerged in as many as 110 countries and regions around the world.

"It is foreseeable that in the future, the global epidemic will continue to run at a relatively high level. China is part of the world and cannot be completely isolated from the world, so the import risk is very large. Wu Fan said.

In addition, the Chinese New Year is approaching. Many overseas compatriots who work, study or live abroad want to go home during the Spring Festival, making the imported cases in Shanghai continue to be at a high level since December 2021. "Last December was the month with the highest number of imported cases since the outbreak began. Will it be higher next? uncertain. Wu Fan said.

Sporadic outbreaks have occurred in many parts of the country. Based on the background of the global, inbound and domestic trends of the epidemic, in Wu Fan's view, shanghai is facing great pressure of "external prevention of import and internal prevention and rebound", and the risks and challenges of epidemic prevention and control are also very huge.

"Recently, there have been many imported cases abroad. Overall, the global covid-19 epidemic is still on the rise, and many places in the country have also experienced local epidemics. "Wu Jinglei said at the meeting that Shanghai is a major port city in China, with a particularly large population, a high degree of concentration, strong mobility, especially as an international metropolis, international exchanges are also very close." Indeed, the overall pressure on prevention and control is continuing to increase, especially to further prevent and control the new crown pneumonia epidemic during the Spring Festival. ”

There is also the cause of the virus itself. Wu Fan said that the virus has been mutating, the speed of transmission has become faster, and the proportion of mild and asymptomatic diseases around the world is increasing. In addition, the virus infects different people and the symptoms are different.

Wu Fan believes that young people who have recently been infected have better physique and immune function, and the possibility of asymptomatic after infection is greater.

Strengthen vaccinations

According to Wu Jinglei, as of 24:00 on January 12, 23,503,700 Shanghai residents had been vaccinated, 22,205,600 had completed the whole process of vaccination, and 8,700,100 people had completed intensive vaccination.

The Spring Festival is approaching, the flow of people is more frequent, and the risk of crowd gathering is increasing. Wu Jinglei called on everyone to adhere to the "three-piece set" of epidemic prevention, keep in mind the "five alsos" of protection, do a good job of self-health monitoring, and have uncomfortable symptoms such as fever, cough, fatigue, and loss of smell and taste, please wear a medical mask to the nearest fever clinic.

At the same time, he called on the citizens who have not yet been vaccinated against the new crown virus, especially the elderly over 60 years old and adolescents aged 3-17, to speed up the completion of the whole process of vaccination. For citizens who have completed the full vaccination and have reached the age of 6 months, we should pay close attention to strengthening immunization.

"High vaccination rates, especially after intensive vaccination, are also increasing for asymptomatic infections. Vaccines can be very effective in reducing the onset of severe diseases. Wu Fan said.

Wu Jinglei also said at the meeting that from the general principle, Shanghai adheres to the strategy of "external prevention of import, internal prevention and rebound", strictly implements the measures of "early detection, early reporting, early isolation, and early treatment", and earnestly grasps the six key points: the entrance to the city, the foothold, the mobile, the employment post, the school door, the monitoring post, and comprehensively strengthens active prevention and control, scientific prevention and control, precise prevention and control, and comprehensive prevention and control.
