HTLV Type I and HTLV Type II Infection among Indians and Natives from Argentina
Endemic foci for HTLV-II infection have been identified in several Amerindian populations. To determine HTLV-I and/or HTLV-II infection among Amerindians living in Argentina we studied 454 sera or plasmas from Indians and natives from different areas of our country. All samples were tested by the pa...
