When you return home, your luggage, clothing and other items need to be disinfected to avoid viruses. Place the clothes, shoes and bags worn outside in the corner of a fixed room, and wash and disinfect them in time. Cell phones, luggage and other belongings can be sprayed or wiped with 75% alcohol concentration. In addition, avoid direct contact of hands with eyes, mouth and nose. After touching other people or objects, you should also wash your hands in time and apply hand sanitizer, soap or hand-free disinfectant to clean them. It is inevitable that you will come into contact with people on the way back, and there is a risk of infection. It is recommended that those who are able to do so isolate themselves for 14 days.
