personal factors that can contribute in the spread of corona virus and indicate how the contribution is

The personal factors that may contribute to spread Corona virus would be:

1). Sneezing or coughing in public without using a mask or handkerchief.

2). Physical contact with people without taking proper precautions like shaking hands without gloves, etc.

3). Not using masks and not maintaining the rules of social distancing.

4). Touching surfaces and mouth and nose without sanitizing it.

Since Corona virus leads to an infectious disease, any contact with the infected person through the droplets left in the air(if one does not wear mas-ks) or physically touching him/her may lead to the spread. This contribution is really huge and may significantly increase the number of infected cases. Thus, people are requested to stay indoors as much as possible and move out(if necessary) with the required precautions(wearing mas-ks, using sanitizers, maintaining social distancing, etc.)
