Disease surveillance system: a mandatory conduit for effective control of infectious diseases in Pakistan.

In Pakistan, absence of a nationwide surveillance mechanism and strategy is the main reason for the failure in effectively controlling communicable diseases. The seasonal outbreaks of various infectious diseases every year call for an integrated surveillance system on a national level for planning effective preventive strategies. Opportunity to adopt a tested and tried model exists at this time in terms of the "Disease Early Warning System" set up by World Health Organization in conflict-affected districts. Replicating this system in other districts is both practical and feasible as technical support is readily available through the World Health Organization. Such a system once put in place has potential to not only decrease morbidity and mortality through early detection and prompt control of outbreaks but also to facilitate effective financial, human resource, and materials management at the district level. This would be a step toward a more responsive health system at the local level.
