Early 2020 to March 2020 is not recommended to wear masks for square dancing.
1, the crowd gathered to increase the risk of cross-infection
We saw the video, the hospital in the medical staff, patients are better protected, the hospital disinfection, protection work is also more in place. At the same time, the hospital arranged for the patients to dance only to take up a little bit of time after meals, so that patients who have been lying down for a long time can exercise properly.
But for the general public who are not infected, the risk of infection should be minimized. If you go to a crowded place at this time of year, it's easy to cause cross-infection.
2, the movement of exhaled gases to make the mask wet, reducing the mask protection time
Said the first point may still be some people retort: "I'm wearing a mask of oh!"
But in fact, you wear a mask when you go to the square dance with you do not wear a mask may be really similar. Because of the square dance time actually belongs to the movement, exercise, when you are doing the action, the breathing rate will be accelerated, this time the exhaled gas will make the mask wet, the mask protection function will be greatly reduced, basically there is no value of protection. At this point, bacteria, viruses may "take advantage of the situation".
