Surgical masks proven to reduce COVID-19 spread by 75%

Research from the University of Hong Kong shows that non-contact virus transmission is reduced by 75% when surgical masks are used.

""The findings implied to the world and the public is that the effectiveness of mask-wearing against the coronavirus pandemic is huge," leading microbiologist Dr Yuen Kwok-yung, from Hong Kong University, said on Sunday."

Dr. Yuen Kwok-yung, one of the world's leading coronavirus experts says ""It's very clear that the effect of masking the infected, especially when they are asymptomatic—or symptomatic—it's much more important than anything else.""

The experiment used two cages of hamsters in three different tests. The infected hamsters' air was pushed via fan to the healthy hamsters.

Without masks, two-thirds of the healthy hamsters became infected, but when masks were used, the infection rate dropped to just above 15%.

In conclusion, when masks are worn by infected individuals, the spread is reduced by 50%. When worn by healthy individuals, spread is reduced by 35%.
