Even with the outer surface tumors that can reach a length of up to 12 nano-meter each, the maximum diameter of a coronavirus is 164 nano-meters which slight more than half the size that even the best face mask can can handle. As I have said from the beginning, the only sure way to avoid infection it distancing and not the 2 meters that the so call experts say, but at least double that. Myth busters did an episode years ago that proved moisture droplets from a sneeze or cough can travel more than 15 feet.
