Community health is a medical speciality that focuses on the physical and mental health of people in a certain geographical area. Initiatives to help community members maintain and enhance their health, prevent the spread of infectious diseases, and prepare for natural catastrophes are all part of this crucial subset of public health. This vital public health sector includes initiatives that assist residents in maintaining and improving their health, preventing the spread of infectious diseases, and preparing for natural catastrophes. For instance, neighbouring plants or waste sites could expose a population to toxins. Community health programmes increase access to preventive health care, include individuals in decision-making about their treatment, and seek reduced medical costs.
