Our objectives were (i) to report the total number of healthcare contacts preceding HIV diagnosis, stratified by type of visit and diagnosis, (ii) to determine how the number of healthcare contacts per persons in follow-up changed in the time preceding HIV diagnosis, stratified by type of visit and CD4+ T-cell count at diagnosis, and (iii) to report the total number and most frequent indicator conditions of HIV infection according to the Finnish and the European Centre for Disease Prevention and Control (ECDC) HIV testing guidelines. Here, CD4 is linked to HIV infectious disease.
