A recent study shows that even herd immunity does not work in controlling corona virus in most effective manner. Rather it is the mask that is the use of universal face masks work most effectively. The study shows if some one who is sick wears a mask it blocks out 90% of the virus when talking and 74% of the virus when cough . It is most preventive when some one is healthy and wears face mask. Along with masking, physical isolation does work broadly and tracing, tracking, testing and treating are the other best possible ways to get a handle on it without lock downs.
