RESUMEN
The Philippines has a rapidly growing HIV epidemic, with men who have sex with men (MSM) accounting for a majority of known cases. Currently, there is little understanding about MSM's experiences of HIV-related stigma in the Philippines and how they influence behavior and quality of life. Twenty-one interviews with MSM living with HIV and with communitybased organization workers were conducted in Manila from June to August 2017. MSM participants were affected by the intersection of HIV-related stigma and stigma toward homosexuality that are rooted in connotations of morality, "dirtiness," and sin. We identified specific patterns by which MSM living with HIV experienced enacted, felt, and internalized stigma and discuss implications of stigma for mental health, delays in HIV testing, and avoidance of HIV health services. Findings support the development of public health strategies in the Philippines that address stigma at societal and individual levels to reduce stigma-related harms.
