Abstract
Since December 2019, the SARS-CoV-2 outbreak that began in Wuhan, China has spread to nearly every continent and become a global health concern. Although much has been discovered about COVID-19 and its pathogenesis, the WHO has identified an immediate need to increase the levels of testing for COVID-19 and identify the stages of the disease accurately for appropriate action to be taken by clinicians and emergency care units. Harnessing technology for accurate diagnosis and staging will improve patient outcomes and minimize serious consequences of false-positive test results. Point-of-care technologies aim to intervene at every stage of the disease to quickly identify infected patients and asymptomatic carriers and stratify them for timely treatment. This requires the tests to be rapid, accurate, sensitive, simple to use and compatible with many body fluids. Mobile platforms are optimal for remote, small-scale deployment, whereas facility-based platforms at hospital centers and laboratory settings offer higher throughput. Here we review evidence-based point-of-care technologies in the context of the entire continuum of COVID-19, from early screening to treatment, and discuss their impact on improving patient outcomes.
