Answers
Answer:
1) Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.
2) Immunisation describes the process whereby people are protected against illness caused by infection with micro-organisms (formally called pathogens). The term vaccine refers to the material used for immunisation, while vaccination refers to the act of giving a vaccine to a person.
3) All the normal functions of the body get disturbed in case illness. So, a nourishing food is required, which is easily digestible and contains all the nutrients. This is the main reason that bland and nourishing food is advised to take during sickness.
4) Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn't infected.
