Lesbian, gay, bisexual and trans (LGBT) individuals have particular vulnerabilities to sexually transmitted infections and HIV infection. Globally, reasons for this include physiological factors, discrimination and poor understanding of their sexual health needs.

This article explores these issues, and makes recommendations for the healthcare profession to address health inequalities and promote improved health outcomes for LGBT populations. This article aims to promote an evidence-based approach that focuses on rights and public health issues.
