Many parents and students are most worried about the rebound, especially the changes caused by overseas imports. Will Chongqing start school in April? The specific starting time depends on the development. It may be until the middle and late April that Chongqing will add imported cases from abroad. Chongqing is an international student with Chongqing nationality in Spain. On March 18, he transferred from Spain to Beijing via Moscow, flew to Chongqing on March 19, and was isolated at the centralized point. On March 22, he was diagnosed, and close contacts were sent to the centralized point for observation. Can Chongqing start school in April? The number of cases in Chongqing has been zero for 30 consecutive days. If there is no imported case on March 22, then it is hopeful that Chongqing will start school in April. As long as the existing diagnosis has not been cleared, even if there is only one person, there will be no red flag on the map. There is still one person diagnosed in Chongqing. In addition to Chongqing, Jiangsu also has imported cases for the first time, and Chongqing does not meet the conditions for starting school. Chongqing has stepped up the prevention and control of foreign countries and minimized the impact. However, the import of foreign countries may affect the opening of schools. This is a problem that not only Chongqing, but also all provinces where imported cases have occurred need to face and wait to be solved. Under the current situation, with the continuous increase of overseas personnel, prevention and control are facing a second challenge. In addition to the existing list of more serious countries, Chongqing has added 8 countries, making a total of 24 countries. If foreigners have been to these countries in the past 14 days, they will all be quarantined for 14 days, and HESUAN testing is also needed. For other countries and regions, centralized isolation or home isolation should be carried out, but testing is still needed. All overseas personnel should be managed in closed loop after entering the country to avoid the recurrence of aggregation. Chongqing strengthens the prevention and control of foreign countries and tries to minimize the impact. If Chongqing can last for 28 days without new confirmed cases, it is possible to start school in the middle and late April. If the number of imported cases from abroad is still increasing, but whether the school will be delayed or not, experts need to assess that the school will start only after it is safe.
