Human Diseases 

We all know health is wealth. We all keep talking about being healthy and fit. When we talk about being healthy, some of us even take it as not being thin or fat. However, today, health is an all-inclusive term. Being healthy refers to a state of complete emotional and physical well-being. It also means that healthcare exists to maintain human health and diseases. We, as human beings, have to follow some guidelines to maintain optimal health.

Health is a feel-good, positive concept. It emphasizes or lays importance on resources for everyday life. It is about social, personal, as well as physical capacities. From our childhood, we have been taught to wash our hands after going to the toilet, before and after eating food, taking a daily bath, etc. Today, health and fitness cover the social and emotional aspects also. A healthy lifestyle means to lead a full life with meaning and purpose.

Relationship Between Health and Diseases 

You must be aware that in the past, the meaning of heath was the absence of disease.  Today, health is more about physical and mental wellbeing.

We can call a condition any disorder that affects health by affecting organs, tissues, or cells within the body of living beings. Diseases can be classified into two types of diseases:         

1 – Communicable Disease

Infectious disease is illnesses that result from direct infections by microorganisms known as pathogens. Such diseases are contagious among individuals. Bacteria, viruses, fungi, and protozoa cause diseases that spread between organisms. Common examples of communicable diseases are

Influenza, contracted by inhaling infected droplets containing the virus.

Chlamydia, a sexually transmitted bacterial infection.
