Novel coronaviruses belong to the genus Coronavirus, family Coronaviridae, and are particularly unprotected because of their small size and much smaller form than bacteria. This virus has an envelope on the outside, is approximately 60-140 nm in diameter, and is round or oval in shape of particles. It is sensitive to UV light and heat, but also to 75% alcohol, ether, formaldehyde, and chlorinated disinfectants, which can be used to inactivate it. It is recommended to actively take protective measures, reduce going out, wear masks when going out, ventilate and wash hands regularly, pay attention to rest, adequate nutrition, and more aerobic exercise to increase body resistance, which are all very beneficial to prevent and control the infection of the virus.
