Stigma refers to a negative attitude toward a person or group, while discrimination is acting on those negative attitudes. HIV stigma and discrimination can take several forms, including refusing medical care to those with HIV, socially isolating them, or referring to them in derogatory terms. Stigma stems from misconceptions about how HIV is transmitted and negative associations with behaviors like homosexuality. It negatively impacts those with HIV through loss of income, family support, and hope. Ending HIV stigma requires openly discussing HIV without stigma, using respectful language, correcting myths, and spreading awareness.
