Answer:

The SARS-CoV-2 virus causes Coronavirus Disease (COVID-19), an infectious disease.

The majority of patients infected with COVID-19 will have mild to moderate symptoms and will recover without any additional therapy. Some, on the other hand, will become critically unwell and require medical assistance.

HOW IT EXPANDS

When an infected person coughs, sneezes, speaks, sings, or breathes, the virus spreads in microscopic liquid particles from their mouth or nose. Larger respiratory droplets to smaller aerosols are among the particles.

If you are near someone who has COVID-19, you can be infected by breathing in the virus, or by contacting a contaminated surface and then touching your eyes, nose, or mouth. The virus has an easier time spreading.
