Trends in Human Immunodeficiency Virus-Related Knowledge and Stigma among Men Who Have Sex with Men in the Republic of Korea from 2012 to 2022.

To evaluate the trends in human immunodeficiency virus (HIV)-related knowledge and stigma among men who have sex with men (MSM) in the Republic of Korea between 2012 and 2022, five cross-sectional surveys were conducted. Though general knowledge of HIV infections is high, some misconceptions persist. The initial set of five questions in the survey maintained consistent levels of understanding throughout the five recurring surveys. Notably, the study found a consistent decrease in personal stigma toward people with HIV/AIDS (PWHA) within the MSM community in Korea. The increasing willingness of individuals to engage in social interaction with HIV-positive individuals, ranging from dining to cohabitation, indicated a positive change in societal attitudes. It is crucial to implement active policies such as counseling, testing, education, promotion, and the creation of preventive programs to improve knowledge about HIV and reduce stigma.
