When riding public transportation, the following actions should be taken to prevent the new coronavirus: 1. Wear a mask: Droplets generated by coughing and sneezing are important carriers of many viruses. The mask can block droplets from entering the mouth and nasal cavity to prevent viral infection. It is recommended that medical surgical masks and N95 / KN95 masks are preferred to effectively protect yourself and reduce the risk of respiratory infections. 2, travel with alcohol-based disinfectant products: contact is an important mode of transmission for many viruses, and it is critical to maintain hand hygiene. When taking public transportation, if you can’t always find soap and water to wash your hands, you can choose alcohol-based hand sanitizer or disinfectant wipes to clean your hands well. It is also important to check the product descriptions to see that the alcohol content is at least 60% to be effective, preferably 70% to 80%.
