What happens when three people are together and two people receive epidemic prevention messages?

If you pass through an epidemic area or are in an epidemic area, then this message is based on personal health punching and the investigation of various risk groups by epidemic prevention and control institutions. When you receive this message, it means that you have been coded yellow, so you can contact the local authorities for consultation. If you are not in the epidemic area, or have not passed through the epidemic area, then don't worry. It may just remind you to protect and take care of you. .

Three elements of epidemic prevention: wear a mask, wash your hands frequently and have more ventilation.
