Answer 1

Step-by-step explanation:

COVID-19 spreads mainly by droplets produced as a result of coughing or sneezing of a COVID-19

infected person. This can happen in two ways:

◆ Direct close contact: one can get the infection by being in close contact with COVID-19 patients (within one Metre of the infected person), especially if they do not cover their face when coughing or sneezing.

◆ Indirect contact: the droplets survive on surfaces and clothes for many days. Therefore, touching any such infected surface or cloth and then touching one’s mouth, nose or eyes can transmit the disease.
