Some important aspects of yaws eradication.

The purposes of a yaws mass campaign are to eradicate yaws and to improve the environmental sanitation and standard of living of the people so that its re-introduction will be impossible. In a mass treatment campaign the importance of latent cases and contacts in maintaining the disease must be taken into account. The treatment of this group of the population, in addition to all active cases, hastens the success of the campaign.Resurveys at regular intervals must be carried out until the prevalence of active yaws is low and there are adequate facilities to continue the consolidation phase of the campaign. All the population should be seen at each survey. Serological screening is used to guide public health activities.All campaigns and post-campaign activities should be planned and budgeted for before the activities start. Campaigns should expand as compact areas and should be co-ordinated with similar campaigns in adjacent countries. Adequate supervision of field staff, the intelligent co-operation of the people and their leaders and continuous project evaluation are essential for the eradication of yaws.
