Advances in Tuberculosis contact investigation in Ethiopia


Contact investigation (CI) refers to the systematic evaluation of individuals who have been in close contact with potentially infectious TB cases within three months of TB treatment initiation. In Ethiopia, the USAID-funded HEAL TB and Challenge TB projects implemented three CI approaches: routine or prospective, reverse, and retrospective. This technical brief describes the implementation of these different CI approaches at different levels of the Ethiopian health system; and includes results and achievements, lessons learned, and recommendations for CI as a cross-cutting TB prevention and control strategy.
