Coronavirus is transmitted between people, usually when someone is exposed to the secretions of the infected person. The transmission of the virus directly affects the transmission route. The current route of transmission of the new coronavirus is unclear, but past experience has shown that exposure to the body fluid that the infected person coughs or sprays, or shaking hands with the infected person lead to infection. If your hand touches something that the infected person has touched and then touches your own mouth, nose or eyes, it may also infect the virus.
Normally, people have about a liter of fluid in their lungs, which, each time they sneeze, spray like a squeezed water bottle. In vitro, they are divided into more than 40,000 droplets, each containing a large number of viruses and bacteria. Because of the huge thrust in the body, the velocity of these liquids can be as high as 35 m / s, and the propagation distance can reach 3~8 m. Come on, this picture is more intuitive.
In 2003, SARS was so horrifying because the speed at which it was transmitted through droplets was beyond control, with the south-east asian flu on monday, south-south china next monday and the whole country next monday.
So be sure to wear a mask! Even if you are exposed to an infected person, wearing a mask can prevent you from inhaling the virus directly from the droplets.
Wash your hands! Even if the virus is left in hand, hand washing can block the virus through the hand into the body.
Nowadays, there is no clear conclusion about the best wearing time of N95 masks abroad, including WHO, and there is no relevant regulation on the use time of Face masks in China.
Some researchers have studied the protective efficiency and wearing time of N95 medical masks. The results show that the filtration efficiency remains above 95% N95 wearing the Face masks for 2 days, and the respiratory resistance changes little, and the filtration efficiency decreases to 94.7% for 3 days.
a suggestion from the us CDC is that in the absence of adequate supply of Face masks, reuse may be considered as long as the equipment is not visibly soiled or damaged (e.g. creased or torn).
