Primary healthcare is crucial for disease surveillance because it serves as a first line of defense for the early identification, tracking, and treatment of illnesses in communities. This function is essential for managing non-communicable diseases, stopping the transmission of infectious diseases, and averting epidemics. Primary healthcare providers make a major contribution to the general health and well-being of the populations they serve through these initiatives.
The multidimensional function of primary healthcare in disease monitoring includes immunization, education, data collecting, early detection, epidemic response, and the management of infectious and non-communicable diseases.
