    Abstract The speed and scale of new information during the COVID-19 pandemic required a new approach toward developing best practices and evidence-based clinical guidance. To address this need, we produced COVIDProtocols.org, a collaborative, evidence-based, digital platform for the development and dissemination of COVID-19 clinical guidelines that has been used by over 500,000 people from 196 countries. We use a Collaborative Writing Application (CWA) to facilitate an expedited expert review process and a web platform that deploys content directly from the CWA to minimize any delays. Over 200 contributors have volunteered to create open creative-commons content that spans over 30 specialties and medical disciplines. Multiple local and national governments, hospitals, and clinics have used the site as a key resource for their own clinical guideline development. COVIDprotocols.org represents a model for efficiently launching open-access clinical guidelines during crisis situations to share expertise and combat misinformation.

    Abstract Background: More than 35 million people in developing countries are living with HIV infection. An enormous global effort is now underway to bring antiretroviral treatment to at least 3 million of those infected. While drug prices have dropped considerably, the cost and technical complexity of laboratory tests essential for the management of HIV disease, such as CD4 cell counts, remain prohibitive. New, simple, and affordable methods for measuring CD4 cells that can be implemented in resource-scarce settings are urgently needed.
    Methods and findings: Here we describe the development of a prototype for a simple, rapid, and affordable method for counting CD4 lymphocytes. Microliter volumes of blood without further sample preparation are stained with fluorescent antibodies, captured on a membrane within a miniaturized flow cell and imaged through microscope optics with the type of charge-coupled device developed for digital camera technology. An associated computer algorithm converts the raw digital image into absolute CD4 counts and CD4 percentages in real time. The accuracy of this prototype system was validated through testing in the United States and Botswana, and showed close agreement with standard flow cytometry (r = 0.95) over a range of absolute CD4 counts, and the ability to discriminate clinically relevant CD4 count thresholds with high sensitivity and specificity.
    Conclusion: Advances in the adaptation of new technologies to biomedical detection systems, such as the one described here, promise to make complex diagnostics for HIV and other infectious diseases a practical global reality.
