How to pick up the mask once it is taken off?
Masks are an important line of defense for respiratory infectious diseases, which can reduce the risk of novel coronavirus infection. The mask can not only prevent patients from spraying droplets, reduce the number and spraying speed of droplets, but also block droplet nuclei containing viruses and prevent the wearer from inhaling. You should continue to wear a mask even after COVID-19 vaccination. For individuals, the protective effect of vaccination is not 100%, and it takes some time to produce protective antibodies. For people, COVID-19 is easy to spread without forming an immune barrier. Therefore, at this stage, we should still adhere to some prevention and control measures, including wearing masks, keeping social distance, washing hands frequently, ventilation and other protective measures.
