How does Coronavirus infection spread in hospitals?

Scientists from China have found that the coronavirus disease can travel in air for up to four metres. The study stops short of saying coronavirus disease spreads through air because of limitations, such as low virus viability in the environment. A high-level US panel found coronavirus disease can spread though speaking and breathing. Meanwhile, India has made it mandatory for everyone to wear masks in public places. A total of over 8,300 infections have been recorded in India so far with more than 200 deaths.
