Primary health care (PHC) addresses the majority of a person’s health needs throughout their lifetime. This includes physical, mental and social well-being and it is people-centred rather than disease-centred. PHC is a whole-of-society approach that includes health promotion, disease prevention, treatment, rehabilitation and palliative care.Primary Health Care, or PHC refers to "essential health care" that is based on scientifically sound and socially acceptable methods and technology. This makes universal health care accessible to all individuals and families in a community. It is through their full participation and at a cost that the community and the country can afford to maintain at every stage of their development in the spirit of self-reliance and self-determination. In other words, PHC is an approach to health beyond the traditional health care system that focuses on health equity-producing social policy. PHC includes all areas that play a role in health, such as access to health services, environment and lifestyle. Thus, primary healthcare and public health measures, taken together, may be considered as the cornerstones of universal health systems. The World Health Organization, or WHO, elaborates on the goals of PHC as defined by three major categories, "empowering people and communities, multisectoral policy and action; and primary care and essential public health functions as the core of integrated health services." Based on these definitions, PHC can not only help an individual after being diagnosed with a disease or disorder, but actively prevent such issues by understanding the individual as a whole.
