Sera from 215 non-drug-injecting Toba and Mataco-Mataguayo pure Indians belonging to four communities in northern Argentina were examined using assays that allow differentiation between reactivities due to type-specific antigens of the human T-cell leukemia/lymphoma virus (HTLV).
Three of these populations have very little contact with non-Indian groups and reside in remote, isolated areas.
HTLV-II type-specific seroreactivity was present in 24 (13.7%) of the 175 Indians older than 13 years of age and in none of the 40 who were of younger ages.
None of the Indians had antibodies reacting with HTLV-I type-specific antigen.
Seroreactivity was more prevalent and appeared at younger ages in females than in males.
