Scientists Exhibit How COVID-19 Infects Respiratory Cells

Three researchers from Washington released microscopic images of the coronavirus infecting lab-grown respiratory tract cells. The images show large number of viruses that spread infection across tissues and to other human beings. Reportedly, the images were first published in the New England Journal of Medicine, and were later re-colourised for easier understanding. Researchers say that the images assert the need to wear masks to prevent the infection.
