Abstract
To clarify the real distribution of HTLV‐I and ‐II carriers among indigenous people in central and South America, blood samples collected from indigenous people in isolated regions of Southern Chile were examined. Among 199 inhabitants from Chiloe Island and Pitrufquen town, three cases (1.5%) showed positive anti‐HTLV‐I antibodies. Two out of the three (82‐year‐old male and 58‐year‐old female) reacted to HTLV‐II‐specific Gag and/or Env proteins but not to HTLV‐I‐specific ones. The latter case was confirmed as an HTLV‐II carrier by polymerase chain reaction test.
