Health is defined as a state of complete physical, mental, and social well-being, while hygiene refers to the practices that help maintain health and prevent the spread of diseases.

•

Diseases are categorized into communicable (infectious) and non-communicable (non-infectious) diseases. Communicable diseases are caused by pathogens like bacteria, viruses, fungi, and protozoa.

•

Pathogens can spread through various modes: Direct contact, infected food or water (H2OH_2O), air (droplets), and vectors like mosquitoes or flies.

•

Vaccination is the process of administering a vaccine to help the immune system develop protection from a disease. It stimulates the body's natural immunityimmunity.

•

Immunity is the ability of the body to resist and fight against specific pathogenspathogens.

💡Examples

Problem 1:

Why is it important to wash hands before eating?

Solution:

To remove pathogenspathogens and dirt.

Explanation:

Handwashing with soap removes harmful microorganisms like bacteria and viruses that may have accumulated on the skin, preventing them from entering the body through the mouth.
