Primary Health Care (PHC) is the essential health care that is made universally accessible to individuals and families in the community through their full participation and at a cost that the community and country can afford. It represents the first level of contact between individuals, families, and the health system. Primary health care is concerned not only with the treatment of disease but also with health promotion, disease prevention, rehabilitation, and maintenance of health. It emphasizes bringing health services as close as possible to where people live and work. The concept of Primary Health Care was internationally emphasized at the Alma-Ata Conference held in 1978, organized by the World Health Organization (WHO) and UNICEF. The Alma-Ata Declaration identified primary health care as the key to achieving the goal of “Health for All.” It recognized health as a fundamental human right and emphasized that people should participate actively in planning and implementing their health care. Primary health care therefore focuses on providing basic, affordable, acceptable, and appropriate health services to the entire population, particularly underserved and vulnerable groups. Primary health care is based on the principle of equity. Health services should be available to all people without discrimination based on economic status, geographical location, gender, age, social background, or other factors. Special attention is given to rural populations, poor communities, mothers, children, older persons, and other groups who may have difficulty accessing health services. The aim is to reduce inequalities in health and ensure that every person has a reasonable opportunity to attain an acceptable level of health. Accessibility is another important feature of primary health care. Health services should be physically accessible, economically affordable, and socially and culturally acceptable. Health facilities should be located near communities whenever possible so that people can obtain care without unnecessary travel or financial burden. Primary health care also encourages the use of appropriate technology that is scientifically sound, practical, affordable, and suitable for the local conditions. Primary health care includes several essential components. Health education is an important component because individuals and families need knowledge about common health problems, their prevention, symptoms, and appropriate use of health services. Education regarding personal hygiene, nutrition, sanitation, reproductive health, immunization, communicable diseases, and healthy lifestyles enables people to take greater responsibility for their own health. Promotion of proper nutrition is also an essential part of primary health care. Malnutrition can contribute to poor growth, reduced immunity, illness, and increased mortality, particularly among children and pregnant women. Primary health care services promote adequate nutrition through nutritional assessment, counseling, breastfeeding promotion, supplementary nutrition where necessary, and education regarding locally available nutritious foods. An adequate supply of safe water and basic sanitation is another important component. Contaminated water and poor sanitation can cause diseases such as diarrhoea, cholera, typhoid, and intestinal infections. Primary health
