we faced a lack of qualified face masks during the rising of the covid-19 pandemic. some countries still are facing doctors recommended face masks to reduce virus. This type of mask will prevent the shortage of masks if the price is good.
A lot of African countries, also some Asian countries have been facing a lack of well-prescribed face masks. Even people don’t know about the best face masks just they are taking masks from the local market for daily use. so, I think these initiatives must help countries to prevent contact of the virus.
Maybe it is a new technology to kill covid-19 like a virus from the mask.
