Expansion of Directly Observed Treatment Short Course Strategy (DOTS)

Implementing partner

• Pan American Health Organization (PAHO)

The most effective public health strategy for reducing tuberculosis transmission is the World Health Organization-recommended Directly Observed Treatment Short Course Strategy (DOTS). DOTS has several elements: government commitment to TB control, TB diagnosis by sputum smear microscopy for patients who report a cough lasting three weeks or longer, standardized and directly observed drug therapy, an efficient and reliable drug supply system, and an efficient recording and reporting system with assessment of treatment results. Through PAHO's activities USAID aims to support the Brazilian National Tuberculosis Program strengthen all elements of the DOTS strategy.

An important goal of PAHO's (Pan American Health Organization) project is the expansion of directly observed treatment. The expected outcome is the reduction of tuberculosis transmission, morbidity and mortality in metropolitan areas of high TB disease burden. In order to achieve these results, PAHO is working through Brazil's extensive Primary Health Care Network, Family Health Program and the Community Outreach Workers Program. This will increase the efficiency and effectiveness of TB control.
