DeMONSTRATE-TB Study in Ethiopia

Ending the TB epidemic by 2035 in Ethiopia would be possible if TB notification declines by an annual factor of at least 15% from the current notification rate of 132 per 100,000 population. This requires highly effective strategies to reduce TB transmission and maximize TB prevention among populations at risk of developing TB, such as Household contacts and people living with HIV. The investigators hypothesize that community wide administration of enhanced TPT will accelerate decline in TB incidence rates when combined with an optimized currently recommended comprehensive TB prevention and care packages described below. The investigators further hypothesize that such intervention packages will be acceptable to the community, providers and policy makers, and that they will be cost-effective. Based on the study results, a TB elimination framework in high burden TB regions and woredas in Ethiopia will be developed, and local evidence to enhance the shift toward TB elimination will be provided as input to the appropriate allocation of resources.
