Background Point-of-care testing (POCT) generates intrinsically fast, inherently spatial, and immediately actionable results. Lessons learned in rural Cambodia California create a framework for planning mobilizing POCT with telehealth interventions. Timely diagnosis can help communities assess the spread of highly infectious diseases, mitigate outbreaks, manage risks. Objective The aims this study were to identify need Cambodian border provinces during peak COVID-19 outbreaks quantify geospatial gaps access diagnostics community lockdowns. Methods Data sources comprised focus groups, interactive learners, webinar participants, online contacts, academic experts, public health officials who determined diagnostic needs priorities outbreaks. We analyzed geographic distances transit times assessed high-risk province, Banteay Meanchey, where people crossed borders daily leading disease spread. strategized rapid antigen molecular aforementioned province applied mobile-testing experience among impacted population. Results difficult isolated areas insufficient meet needs. median time from (n=17) sites was 73 (range 1-494) minutes, Meanchey Province (n=9 districts), 90 10-150) minutes. Within provinces, maximum versus minimum differed significantly (P<.001). Pareto plots revealed are not centrally located. At epidemic peaks Southeast Asia, mathematical analyses showed that only one available test met World Health Organization requirement sensitivity >80%. observed Solano Yolo counties, California, vending machines libraries dispensing free kits 24-7 improved diagnostics. Mobile-testing vans equipped antigen, reverse transcription polymerase chain reaction, multiplex influenza A/B proved useful differential diagnosis, awareness, travel certifications, treatment. Conclusions Rural portals implemented demonstrated feasible strategy Cambodia. Automated dispensers mobile respond case surges enhance preparedness. Point-of-need resilience assure spatial justice. Public assets should include higher-quality, lower-cost, readily accessible, user-friendly POCT, such as self-testing home tests, distributed detection surveillance, quick High-risk settings will benefit synthesis geospatially optimized automated access, timely asymptomatic symptomatic patients at points now, new future pandemics.
