Absence of HTLV-1/2 infection and dermatological diseases in Manaus, State of Amazonas, Brazil.

Introduction: The prevalence of human T-cell lymphotropic virus types 1 and 2 (HTLV-1/2) infection is heterogeneous across different populations. We tested the hypothesis that HTLV-1/2 infection occurs more often in dermatological patients.

Methods: A total of 1,091 patients from a tropical dermatology clinic were tested for HTLV-1/2. In parallel, 6865 first-time blood donors from the same geographic area were screened for HTLV-1/2; HTLV-1/2 positive blood donors underwent dermatological examinations.

Results: The prevalence of HTLV-1/2 in first-time blood donors was 0.14%. No co-occurrence of HTLV-1/2 infection and dermatological conditions was observed.

Conclusions: Our results challenge the hypothesis that HTLV-1/2 infection occurs more often in dermatological patients.
