Do not check your health in low-risk areas.

At present, the COVID-19 epidemic in China has been effectively controlled since the beginning of 2020, and the epidemic prevention measures in China are effective and worth learning. Most provinces and cities in China have cleared the number of people infected with COVID-19 epidemic, which can be called low-risk areas. At present, the middle and high risk areas are mainly caused by imported food from abroad. The epidemic situation abroad is severe, and the number of confirmed cases in COVID-19 is increasing every day, which leads to the decrease of food safety. Then for the students who return to school in the second half of the year, the high-risk areas still need to issue nucleic acid reports within one week. In high-risk areas, the time for nucleic acid detection can be less strict.

First, the school should do a good job in prevention and control in the second half of the year.

With the COVID-19 epidemic basically under control, major areas in China have announced the start time of the second half of the school year. In view of students returning to school, the school still needs to take certain epidemic prevention measures. To some extent, students who come to school should be tested and screened. If they have recently come from high-risk areas, they still need to be quarantined.

Second, some testing measures need to be taken for high-risk areas.

At present, schools in high-risk areas in China, such as Lufeng in Guangdong and Urumqi in Xinjiang, can postpone the start of school accordingly. Students from these areas must pass certain examinations if they want to study in other places. Schools should also screen students in these areas to avoid large-scale COVID-19 infection.

Third, students should pay attention to the consumption of food.

In the process of studying abroad, students basically don't process what they eat, but buy it. In this case, you need to pay more attention. At present, some foreign foods may be contaminated by COVID-19, whether it is food itself or food packaging. So try to eat school meals, and try to reduce the consumption of imported food when it is unnecessary, especially frozen food.
