TB case contacts tracing

Hello. For TB cases surveillance, We have been collecting aggregate values for case contacts as alternative to have data on contacts follow up through a “Contact investigation stage” for TB cases tracker, now NTP needs to have full contact tracing linked to index case and analysis. Has any further dev done to strengthen this area? Any typical use case? Please share or drop me a message at (akamugunga@hisprwanda.org) Thanks!
