The specific operation of going out and returning home mainly depends on the density of population in the space of going out: 1. Returning from the open environment: the pathogens of respiratory diseases are mainly transmitted through droplets, with a range of about 1 meter. Return home from the open space, wash hands in time, change clothes, you can meet the protection requirements, do not have to panic too much; 2, return home from the densely populated places: from the station, hospitals and other densely populated places to return home, it is recommended to disinfect the clothing treatment. Clothes if not contaminated, available 75% alcohol spray all over the body, drying to the balcony ventilation. If they have been contaminated, they can be soaked in 500mg/L chlorine disinfectant for 30min, washed with water and dried. Source: Dr. Yurai
