HJFMRI and its parent company support the U.S. Military HIV Research Program and its collaborators in conducting cohort and epidemiological studies of HIV and other sexually transmitted infections (STIs) in sub-Saharan Africa, Europe, the Middle East, and Southeast Asia. 

The Multinational Observational Cohort of HIV and Other Infections (MOCHI) is a prospective observational study that provides one unified protocol and set of data collection instruments for deployment across multiple sites in diverse regions of world. MOCHI prepares for future HIV and STI prevention studies by estimating HIV and STI incidence in high-risk populations, tracking the evolution of risk and healthcare-seeking behaviors, building site capacity, and maintaining relationships with communities affected by HIV and other STIs. The study will also help further characterize acute HIV infection, response to therapy, and long-term outcomes.

In the Middle East, HJFMRI supported the Walter Reed Army Institute of Research and collaborators in conducting the first observational HIV study to take place in the Kingdom of Jordan. This research characterized the evolving HIV epidemic in the country, gathering information on HIV risk factors, outcomes, genotypes and drug resistance profiles.
