"There are multiple, complex, and causal pathways between sexual violence, coercion, and fear of abuse and increased HIV risk. Violence victims often have limited ability to refuse unwanted sex and negotiate safe sex. Genital trauma during forced or unwanted intercourse can facilitate HIV transmission.
