1. Pay attention to the separation of raw and cooked food: Recently, COVID-19 nucleic acid has been frequently detected in cold chain food and its outer packaging, and special attention should be paid to the separation of raw and cooked food when handling fresh/frozen food to prevent cross-contamination.

2. Keep a distance of one meter when waiting in line: COVID-19 can be spread by short-range droplets, and people are easy to gather when waiting in line, so attention should be paid to keeping a distance above 1 meter.

3. Don't forget small items such as mobile phones when cleaning: COVID-19 virus can spread through contact. Small objects with high frequency contact such as mobile phones, mice and keyboards should be cleaned and disinfected regularly.

4. Wear a mask during the whole process of using public toilets: public toilets are easy to shelter evil people from evil practices and have a large flow of people. If disinfection is not timely, the virus can easily remain in the environment. Wear a mask before entering the public toilet.

5. Pay attention to personal protection in elevators, cinemas and other closed places: in a narrow space, the distance between people is small, the environment is closed and the air is not circulating, which is more conducive to the spread of COVID-19.
