Answer 1

Answer:

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

Ways people spread infectious diseases-

1.Through the air

Droplets containing small particles of a disease, such as measles, chickenpox and influenza (the flu), can be present in the air when an infected person coughs or sneezes.

2.Through direct contact

Touching an infected animal, person or their bodily fluids and not washing your hands, increases your risk of giving yourself and others the infection.

3.Through contact with contaminated surfaces or objects

Touching a surface or object that has been contaminated by an infected person’s disease particles and not washing your hands, increases the risk of giving yourself or others the disease. 

What do u mean by immunization?

Answer. Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body’s own immune system to protect the person against subsequent infection or disease.
