Communicable diseases are the most common causes of death, illness and disability in most developing countries. These include malaria, measles, cerebrospinal meningitis, cholera, yellow fever, Lassa fever, Tuberculosis, HIV/AIDS, diarrhea and Pneumonia etc. The federal ministry of health has developed programmes for the elimination, eradication, prevention and control of these diseases with technical support from development partners.
The resultant effect of poor surveillance system is poor control measures which results in high mortality, morbidity and disability which were characterize by the initial Disease Surveillance and Notification system (DSN) in the country before the introduction of the present integrated disease surveillance and Response (IDSR) strategy. The World Health Regional Committees for Africa advocated IDSR in 1998 at its 48th session.
