Abstract:
:In Western countries, HTLV-1 infection is recognized mainly among foreigners coming from endemic areas. In contrast, HTLV-2 is found predominantly in native intravenous drug users (IDUs). Spain has experienced a large wave of immigration, which could have influenced the current prevalence and distribution of HTLV-1 and HTLV-2 infection. A 1-day cross-sectional survey was carried out in May 2005 in 13 hospitals distributed across Spain. A total of 2873 outpatient subjects were screened for HTLV-1/2 antibodies. Although the majority of the study population consisted of native Spaniards, 206 (7.2%) were immigrants. Two cases of HTLV-1 and one of HTLV-2 infection were found (overall prevalence, 0.1%). The two individuals with HTLV-1 were immigrants from endemic areas and the single case of HTLV-2 infection was a former Spaniard IDU coinfected with HIV-1. In summary, the current prevalence of HTLV-1/2 infection in Spain is low, with no evidence of spread beyond the classical risk groups. However, a rapidly growing population of immigrants from HTLV-1-endemic areas in Spain could modify this pattern and periodic surveillance studies including both natives and immigrants are warranted.
