When human being with COVID-19 breathe the end or cough, they expel small droplets that contain the virus. This droplets can get in the mouth or sleep of someone without the virus, leading to an infection to occur.

The many common means that this illness spreads is v close contact with who who has the infection. Close contact is within about 6 feet.

These numbers are likely to change as the instance evolves. However, they suggest that COVID-19 is much more deadly 보다 influenza. For example, seasonal influenza commonly leads to death in much less than 0.1% of cases.

When trial and error becomes easier and much more widespread, health professionals will have a an ext accurate understanding into the exact number of severe cases and deaths.

SARS is another kind of coronavirus. It became a global pandemic in 2002–2003. About 9.6% that SARS cases led to death. However, COVID-19 is more contagious, and also it is already the reason of an ext deaths worldwide.
