Abstract:

Undiagnosed HIV cases contribute to the increase in new infections, estimating this figure is important to evaluate strategies in HIV control programs. The objective of this study was to estimate the number of undiagnosed HIV cases in the Cajamarca Region, Peru between 2015 and 2021. HIV cases were obtainedthree sources of information: The Regional Health Strategy for HIV Prevention and Control (ESPC-HIV); the HIV epidemiological notification application (Noti-HIV) and the laboratory information system (Netlab). The three databases were linked; a capture-recapture analysis using a log-linear model provided estimates of the number of undiagnosed HIV cases, taking into account interactions and Akaike\'s information criterion. After linking, 991 registered HIV cases were obtained. An estimated 1388 cases (95% CI: 1265.6-1542.8) of people living with HIV were estimated, of which 393 (28.4%) were not diagnosed. The underreporting of each source was 51.9% in the ESPC-HIV, 63.6% in Netlab and 88% in Noti-HIV. It was concluded that a high number of HIV cases went undiagnosed, and strategies needed to be reconsidered to increase the systematic detection of HIV cases.
