diseases that don't spread by contact with
a sick person.
Answers
Answer:
A person might have a non-infectious diseases by the following ways:-
a.) Inherited diseases:- These diseases are passed down from generation to generation. Example:-Sickle Cell anaemia, Diabetes
b.) Lifestyle diseases:- These diseases are caused by our lifestyle. Example:- Cancer, Heart attack
c.) Injuries:- These are diseases which include fractures, ligament tear, burns, cuts,etc.
The disease might be measles which can spread even if we come in the room of that person or it might be Chickenpox which a airborne disease and can also spread if we come in contact with the blisters of that person or as in Covid 19 if a sick person touch anything and a healthy person touches it after him and then touches his face the virus might pass into him that's why its recommended to not to touch our face and cover our face until a cure is found.
