Question

What do we need to prevent and treat illness?

Answer 1

Hint: Illness is the feeling of not being well. Illness is anything that requires attention, such as pain, discomfort, anxiety, weakness, exhaustion, and so on. These two phenomena are obviously not mutually exclusive, and they frequently occur simultaneously. Disease is a condition that must be treated. Illness is something that must be dealt with.

Complete answer:
To solve this question one should know the difference between three terms which look very similar but are different in meaning. However, the three of them might be interrelated to each other. These terms are – Illness, Infection and Disease.
Illness is any kind of discomfort leading to a feeling of not being well. Infection on the other hand is always related to an entry of a pathogen inside the human body and its multiplication. However, the term disease signifies any disorder in body function and structure. Illnesses may be a result of infection and disease. Also, any illness may proceed into a disease or may be a sign of a disease.
For example – Discomfort in breathing is an illness but it can be a sign of respiratory infection or disease like pneumonia, common cold etc.
So, any illness should not be completely ignored and various measures can be taken to prevent and treat illness. Some of them are mentioned here –
Living a healthy lifestyle like avoiding smoking, alcoholism, drug addiction etc.
Have nutritional food choices and avoid fast food and too much sugary, oily or salty food.
Regular exercising.
Proper sanitation habits.
Access to good health care facilities etc.

Note:
Health is defined as a state of being physically, physiologically, mentally and socially in good condition. Wellness and Health are two terms which are often used interchangeably. There are several things that are crucial for one’s health. Housing, financial stability, community safety, jobs, education, and the environment are among them. These are referred to as health's broader determinants.
