Le Thi Nguyen Q, et al. – This cross– sectional study aimed to investigate the coverage and barriers of health insurance (HI) among people living with HIV (PLWH) in Vietnam. The data presented in this work showed a high proportion of PLWH was not covered by HI. The findings suggested that lacking information about HI and feeling difficulty in accessing HI were primary barriers that should be resolved via timely educational campaigns and consultations as well as supports from families in order to expand effectively the HI coverage.
