Brief summary
While HIV prevalence among Men Seeking Men (MSM) in India is 10-15 times higher than in the general population (4.3% vs 0.3%), current interventions for Indian MSM have limited reach. In order to reduce the burden of HIV in MSM, innovative, far-reaching prevention and treatment strategies are needed. Guided by the increase access to internet-based social and mobile technologies (SMT) (e.g., SMS, WhatsApp, dating apps) globally and in India, this is a 3-arm parallel, pragmatic randomized controlled trial of community-developed, theory based behavioral intervention (CHALO! 2.0) delivered via WhatsApp (secure SMS application) compared to an Attention-Matched Control, or a Digital Coupon for free HIV testing only control conditions. The primary outcomes are HIV-testing at 6 months (3 months after the end of the intervention) and linkage-to-preventive care (counseling or pre-exposure prophylaxis) at 12 months. The secondary outcomes are the frequency of HIV-testing by 18 months.
Interventions
The components of the intervention are: Contents of digital-media (sent twice/week for 12 weeks) on the following topics: HIV testing, prevention, treatment, linkage-to-care; Personalized digital coupon for free testing; Webpage listing testing/ care sites; access to online outreach workers.
The components of the intervention are: Contents of digital-media (sent twice/week for 12 weeks) only related to general health information; Personalized digital coupon for free testing; Webpage listing testing/ care sites; access to online outreach workers.

Study design
Masking description
The Data Manager (who has no contact with study participants) will assign participants to a study group and cross-reference encrypted files with our technology consultant. Participants will be unaware of arm assignment and will receive automated messages to complete online surveys. Study staff collecting HIV testing and linkage-to-care outcomes will also be blinded to the participants' study arm. Finally, the team of Virtual Peers will not be informed of study hypothesis.
Intervention model description
Subjects meeting all eligibility criteria will be randomized to one of three study arms. Participants will be assigned either to CHALO! 2.0 (intervention), to an Attention-Matched Control, or to a Digital Coupon for free HIV testing only arm. After baseline survey completion, the research team will use random blocked design, with a fixed block size, to stratify randomization by prior HIV testing history (never tested vs. not tested in \>6 months).

Inclusion criteria
* live or work in Mumbai or Thane * fluent in Hindi or English * have had anal sex with men in the past one year * report that they have either never been tested for HIV, are unaware of HIV test results, or are HIV-negative with last HIV test at any time, and have engaged in anal sex since last HIV test * able to provide and verify a WhatsApp mobile number and email address * willing to answer online surveys for 18 months
Exclusion criteria
* participating in a concurrent HIV-related study * intention to move out of the Mumbai metropolitan area in the next six months

The number/percentage of participants who received status neutral counseling treatment within 12 months from randomization is summarized by study arm/group. |
| Sexual Behaviors - Consistent Condom Use | Within 18 months from randomization | Sexual Behavior will be evaluated based on consistent condom use. Specifically, this measure will be assessed as a dichotomous (yes/no) measure as to whether participants engaged in condomless anal sex during the study. Results will be summarized by study arm. |
| Sexual Behaviors - Number of Sexual Partners | Within 18 months from randomization | Sexual Behavior will be also be evaluated based on the number of sexual partners a participant had during the course of the study.
