What demographic group accounts for more than half of HIV infections?

The demographic group that accounts for more than half of HIV infections is African Americans. This high prevalence can be attributed to a variety of factors, including socioeconomic disparities, lack of access to healthcare, stigma surrounding the disease, and higher rates of other sexually transmitted infections, which can increase susceptibility to HIV.

Historical and systemic issues, such as discrimination and barriers to healthcare, have also played a significant role in the impact of HIV within African American communities. Increased awareness, education about prevention, and treatment programs targeted specifically at African Americans are crucial in addressing the epidemic and reducing new infections.

While other demographic groups also face significant rates of HIV, the data consistently shows that African Americans represent the largest percentage of those living with HIV in the United States.
