Mask legend, sometimes the truth can be self-evident
Dr. Seeto 

 

 In the United States and Western countries, many doctors and policy personnel in the early days of the COVID-19, said: There is no scientific evidence to wear masks.  Indeed, no clinical research data on double-blind control of mask effectiveness has been found.

 

 But the three stories I listed, do you still think you need to do double-blind research?

 

 

 The first story happened during the influenza pandemic of 1918. The Times reported that the ocean liner sailing between the United States and the United Kingdom suffered a serious infection from New York.  After returning to the United States, the captain ordered all crew members and passengers to wear masks after learning about the use of masks in San Francisco.  Despite the high infection rates in Manhattan and Southampton on the return trip, there were no reports of shipboard infections during this return trip.

 

 The second story comes from a recent report in New York: According to data from 27,000 employees in 25 medical institutions in northern New York State, 12.2% of medical personnel in five administrative districts of New York City were diagnosed with COVID-19, compared with 19.9% ??of the general public.  In other words, the infection rate of medical staff in the emergency room is lower than that of ordinary citizens.  why?

 

 The third story is the legend of Hong Kong. Hong Kong has a population of nearly 8 million, and only four people died from COVID-19 ,Hong Kong ’s housing conditions are not better than New York. The population of New York is also more than 8 million, and at least 23,000 people died from COVID-19

 

 Looking at the three stories above, the benefits of wearing masks are self-evident.  There is no need to do any double-blind control research for this. Wearing masks is only a few effective measures currently known: wear masks , social distancing at least 6 feet or two meters apart and wash hands frequently.
