The active search for cases of Tuberculosis (TB) aims to ensure early detection to reduce the risk of poor outcomes of the disease and the social consequences of the disease, as well as to cut the chain of transmission in the community in a timely manner.


. To determine the current status, challenges and operational solutions to the Active Searches in the 18 Health Regions of Paraguay.

field visits were analyzed for active searches, in three types of interventions, 5089 people investigated, 26.5% were identified as RH. The overall positivity was 5%. It takes an average of 76 persons to find a TB case. The active searches that had the greatest impact were those conducted by the national level with 49.3% of TB cases contributed.
