Kameoka-HIV_spread-Map (IMAGE) Kobe University Caption According to the data of the Kobe University research team, the HIV substrain dominant in Southeast Asia was brought to Thailand around 1977, from where it started to spread through this part of the world. The virus was brought to Indonesia at least three different times, sometimes via different countries such as Vietnam and Laos. And while it was mostly Thai substrains that spread to other parts of the world, it was an Indonesian substrain that moved on to Iran. Credit S.Q. Khairunisa et al.
