title: First Appearance of HIV-1 CRF07_BC and CRF08_BC Outside China.
abstract: Neither full length genomic sequence of CRF07_BC nor that of CRF08_BC was found in any other countries since they originated in Yunnan, China, in early 1990s. Here, we first report that CRF07_BC and CRF08_BC appeared among intravenous drug users in Shan state of Myanmar bordering Yunnan, and confirmed that they spread from China to Myanmar. The introduction of CRF07_BC and CRF08_BC in northern Myanmar may forebode a changing subtype epidemic in Southeast Asia.
