Answer 1

Hey!!
Thanks for the question!!

Here is the answer..​ 

It depends on the type of sickness.
For example,
If it's a cold , be sure that you are not near them when they are coughing or sneezing.

Similarly, if someone is suffering from cancer, 
Cancer is a non communicable disease, hence it cannot pass or spread one people to another.

But, Infectious diseases are transmitted from person to person by direct or indirect contact of person. 

Also,

1. Through Direct contact​ :

Diseases which are spread by direct contact are called contagious diseases . They can also be spread through objects touched by the infected person.

2. Through indirect contact​ : 

Infectious diseases can also be spread indirectly through the air or any other means.

Hence, it's not like that all diseases spread to people comming in contact with a sick person.

I hope my answer helped!!

Thanks!
