People incarcerated in US prisons have been disproportionately harmed by the COVID-19 pandemic. That are such efficient superspreading environments can be attributed to several known factors: small, communal facilities where people confined for prolonged periods of time; poor ventilation; a lack non-punitive areas quarantine/medical isolation; and staggeringly high numbers experiencing incarceration, among others. While health organizations issued guidance on preventing mitigating infection...

Abstract Financial incentives have demonstrated effectiveness in improving outcomes for people living with HIV; however, little is known about their impact on intimate partner violence (IPV) this vulnerable population. A cluster-randomized trial investigating financial and viral suppression was conducted the Lake Zone of Tanzania (clinicaltrials.gov: NCT0420135). Between May 2021-March 2022, 32 clinics were randomized 1:1 to receive standard care (SOC) or offer 22,500 TZS (~$10 USD)...
