To improve the coverage of STI, HIV, TB, and Hepatitis services among the incarcerated population in Prisons, Other Closed Settings, Juvenile Homes, and Drug Deaddiction Centres, the National AIDS Control Organisation (NACO) has launched the Integrated STI, HIV, TB, and Hepatitis (ISHTH) Campaign. This campaign is implemented in close collaboration with the National Tuberculosis Elimination Program (NTEP) and the National Viral Hepatitis Control Program (NVHCP) under the National Health Mission. To facilitate efficient and timely reporting of data from these institutions on a daily basis, a mobile application has been developed. This mobile app allows for the monitoring of data at both the national and state levels. It is designed to be user-friendly and has the capability to synchronize offline data, ensuring that data can be collected even in areas with limited or no internet connectivity. By utilizing this mobile app, the reporting process becomes streamlined and standardized across institutions. It enables real-time monitoring of the campaign's progress, facilitating prompt interventions and the identification of areas that may require additional support or resources. The mobile app also enhances data accuracy and quality by reducing manual errors and data entry discrepancies. It provides a reliable platform for capturing and analysing data related to STI, HIV, TB, and Hepatitis services, helping to inform decision-making and resource allocation. Furthermore, the ability of the mobile app to synergize offline data ensures that data can be collected even in situations where internet connectivity is limited or intermittent.
