Summary

This study tested whether sending supportive messages and information through WhatsApp could encourage men who have sex with men in Mumbai and Thane, India, to get tested for HIV and connect with preventive services like counseling or PrEP. Over 1,000 men took part, and the program aimed to make testing and prevention easier to access. The results show how mobile technology can help reduce HIV in high-risk communities.
