Primary Health Care as the Platform for the Double Burden of Disease

Health systems in Tanzania and many other settings have spent decades building programmes for maternal health, HIV, tuberculosis and vaccination while hypertension, diabetes, cancer and other chronic diseases have grown alongside them. This is not a transition from one burden to another. It is a double burden, often managed through systems that remain organized vertically.

Primary health care is where these pressures meet. A person may need HIV treatment and hypertension care, reproductive-health services and diabetes screening, or maternal care and chronic-disease management at the same time. Tanzania’s first International Primary Health Care Conference highlighted data-driven PHC, financing, community-health-worker roles, workforce capacity, political commitment and the challenge of incorporating NCD services into historically disease-specific systems. Chronic-disease programmes, infectious-disease platforms, cervical screening and maternal referral all point toward the same organizing principle: the patient should not have to reconstruct a fragmented health system at every visit.

PHC therefore becomes a platform rather than another programme category. The scientific challenge is to decide which services belong together, at which level of care, with what workforce, data and financing architecture.
