Since the epidemic, people’s health awareness has increased significantly. Not only do you need to pay attention to your own hygiene habits, but you also need to pay attention to social distance between you and others. For example, when entering crowded areas, take the initiative to wear a mask and maintain a certain safe distance. At present, my country's epidemic prevention is the best. There are no local cases, and the new ones are all imported cases. Although there were some cities in the middle that had a second rebound, such as Harbin, Jilin, Beijing, Urumqi and other cities, they were all brought under control one after another. Compared with the epidemic spreading around the world, China is definitely the safest place. But if we still relax, we need to strengthen monitoring and we cannot relax. On August 12, the Nanjing Municipal Health Commission received a notification that on the 11th, a Nanjing citizen tested positive for the new coronavirus in Japan. After receiving the report, the Nanjing Municipal Health Commission attached great importance to it, immediately launched an epidemiological investigation, and took prevention and control measures for relevant close contacts. The woman is from Nanjing. She traveled to Quanzhou, Fujian and other places between August 2 and 6, and then went to Nanjing Second Hospital for a nucleic acid test on August 9. The result was negative. Fly from Nanjing to Dalian on August 10, and fly from Dalian to Tokyo, Japan on August 11. After entering the country, the Japanese health department tested him for the new coronavirus, and the result was positive. He has been quarantined and currently has no symptoms. Therefore, the woman’s domestic activity trajectory is Nanjing, Quanzhou, Nanjing, and Dalian. The Nanjing Municipal Health Commission took timely measures to isolate and conduct nucleic acid tests on people who were in close contact with the woman. Fortunately, all the people in close contact were negative. At the same time, the woman's people during the trip were quarantined and observed, and no suspected cases have been found so far.

We are currently doing the best to control the transmission of the new coronavirus. Thanks to our mature system and complete preventive measures, as soon as a suspected case appears, the emergency mechanism can deal with it calmly. First, the suspected patients and people in close contact will be isolated and tested as soon as possible, and then everyone involved will be screened through epidemic control. Isolate and test to ensure that all contacts do not have the opportunity to spread the disease. This approach is the most effective, and it minimizes the crowd and prevents it from spreading. Although we are very effective in controlling the epidemic, many countries are still on the rise because the world has not yet brought it under control. Therefore, whether you are leaving the country or entering the country, inspections are relatively strict. Especially those entering the country need to be quarantined and inspected. Generally, at least 14 days of quarantine inspection are required. For ordinary residents, although there are no local cases now, it does not mean that it is safe. They still need to take more precautions. For example, try to wear a mask to the supermarket, wash hands frequently, disinfect frequently, maintain normal social distance, and develop good hygiene habits. . Try to avoid going to areas with high epidemic risk, and go to the hospital for treatment in time when symptoms such as fever and cough occur.

Although the Nanjing woman tested positive in Japan this time, the people around her were not infected. However, according to the rules of infectious diseases, where did she get the infection? I'd also like to know the answer.
