why you need a plastic mask shield to protect yourself

How on earth are humans infected with the new coronavirus? A new study by the university of hong kong has shown that the eye may be an "important route" for human infection with the new coronavirus, which is more likely to infect the respiratory tract and conjunctiva of humans than the SARS virus. This explains why new coronavirus is more likely to spread in people than new ones. The study, published May 7 in the world's top academic journal Lancet-Ret Respiratory Medicine, was co-authored by Chen Zhiwei, associate professor at the School of Public Health at the University of Hong Kong's Li Ka-shing School of Medicine.

This study demonstrated that the new coronavirus can infect human bronchus, lung, and conjunctiva by culture the new coronavirus in vitro. The University of Hong Kong (HKU) study confirmed that the new coronavirus can infect the eyes and that the virus can be transmitted through some eye secretions such as tears. This is very important for the prevention and control of infection, and also provides a direct scientific basis for "frequent hand washing" in the requirements of epidemic prevention.

the new coronavirus not only has the ability to replicate in many human tissues, but also has a variety of transmission routes. the study also proved that the new coronavirus has strong replication ability by comparing the replication ability of SARS virus, MERS( middle east respiratory syndrome), influenza a virus H1N1 influenza virus in many tissues. It also explains why the new coronavirus is so powerful that it can quickly spread to more than 3.73 million people worldwide within four months of the outbreak.
