| Research Abstract |
This study has been to evaluate, with retrospective cohort, the impact of dual infection of HTLV-1 and Hepatitis G virus on maternal to child infection of HTLV-1, main transmission route of which is maternal infection, let alone horizontal transmission through blood and sexual contact. By the time of the last year, we established RT-PCR enable to detect hepatitis G virus. As a consequence, we obtained the result that infection rate of HGV was 0.8 percents. On the other hand, we also have gotten the result that there have been two subgroups of HTLV-1 existing in Japan, and those were divided around 20 to 40 thousand years ago.
