Of all WHO regions, the Americas have the second lowest rate of successfully treated TB cases and the largest percentage of failed treatment cases. Peru in particular has the highest percentage of previously treated TB cases with MDR-TB (multi-drug resistant tuberculosis), often caused by patients not adhering to the treatment. This innovation aims to rectify this with a cost-effective and community-centred approach, using eCompliance, a portable biometric patient identification system originally developed by the NGO OperationASHA.
