Introduction/objective: Transnational populations from the Association of Southeast Asian Nations are crossing borders regardless of whether their status is legal or undocumented, to receive health services in the border regions of Thailand. The implications and challenges of transnational mobility and the utilization of public health facilities in Thailand's border regions are therefore investigated in this study.
Methods: Four public health facilities were selected, located in 2 economically-active border areas in Northern Thailand: Mae Sai-Tachileik at the Thailand-Myanmar border and Chiang Saen-Ton Phueng at the Thailand-Lao PDR border.
