Can we estimate HIV incidence using the RTRI or RITA results?

Although the primary objective of the recent infection surveillance system does not include HIV incidence estimation, surveillance data may be used to estimate national and sub-national HIV incidence as a secondary objective. Importantly, the system will only include populations that access HIV testing services, thus complex weighting will be required to adjust for individual testing probabilities and missing information for populations that do not access testing. Additional data are needed for HIV incidence estimation: number receiving HIV testing, number of HIV negatives, number of known HIV positives, and number testing recent by RITA.
