As the weather gets hotter, people have been very concerned about whether to wear masks or not. There is a principle here that it is not necessary to wear masks in well ventilated areas. As long as it is well ventilated, it can be said with some confidence that it should be safe.
Which situations do not require masks? In outdoor spacious places, such as playgrounds, parks and sparsely populated streets, you don't need to wear masks. In addition, there is no need to wear masks at home, as well as workplaces in low-risk areas, like offices, building sites and factories. It is even more unnecessary to wear a mask when exercising outdoors. Low-risk areas where have no need to wear masks also include schools. To summarize, for those who do not travel frequently to other unfamiliar places and live in relatively fixed environment of low-risk areas, basically no masks are needed in such cases.
Which places need to pay special attention to wear masks? Closed places with poor air circulation, like in closed vehicles such as planes, high-speed rails, subways, buses and the same environments; closed public places, for example, places with poor ventilation such as elevators. Special attention should be paid to wearing a mask when visiting or accompanying relatives and friends to hospital. In addition, masks should be worn at public service windows, such as cash registers in supermarket and bank counters. In conclusion, as for wearing masks, the main principle is that good ventilation means less risky. Be highly cautious to enclosed spaces. Beyond that it should be determined according to the situation. (According to the Chief Expert of Epidemiology from CDC.)
