Chapter 3 : Setting up surveillance systems

Disease surveillance essentially concerns gathering information that is critical for rationally planning, operating and evaluating public health activities. Participants of disease surveillance programs receive reports from sources which are both official and unofficial. Information from official sources originates from the local health care providers who see patients, passes from the local public health officer to one or more intermediate levels (such as city, state and province) and from there, goes to the national epidemiology group. Member Governments of the World Health Organization have agreed about procedures for international notification of selected diseases, and the method of reporting and emergency measures to be taken (29). In the handbook Control of Communicable Diseases in Man, the procedures re discussed in detail and the category of each contagious disease is in dicated (27). Only cholera, plague, smallpox and yellow fever are currently subject to the International Health Regulations. Four other diseases, influenza, louse-borne epidemic typhus, louse-borne relapsing fever, and malaria, are under international surveillance.
