Resumen

In the present study we describe and characterize the geographic distribution of HTLV-1 and 2 positive cases from Peruvian patients with presumptive diagnosis 2019-2021. Of a total of 555 confirmed positive samples, 546 (98.4%) were HTLV-1 and 9 (1.6%) HTLV-2. In addition, 22 of 24 departments of Peru presented cases of HTLV-1. The main reasons for requesting a confirmatory diagnosis being: aspiring to donate blood with a reactive screening test, suspicion of leukemia/ lymphoma and tropical spastic paraparesis. The results reflect that the identification of critical points constitutes a persistent gap regarding the diagnosis, being crucial to reduce the number of new cases in Peru.
