Early detection and diagnosis allow isolation of the infected patients and contact tracing, which can mitigate the spread of the virus and save lives, especially when a significant number of the patients are asymptomatic.

Current methods used in SARS-CoV-2 detection Developing low-cost and rapid testing methods for early detection of infection has always been a challenge while dealing with the current COVID-19 pandemic. Presently, two approaches are being used for the detection of COVID-19 infection. The first one detects the viral genome and uses techniques such as genomic sequencing, CRISPR, and reverse transcription real-time quantitative polymerase chain reaction (PCR). While these methods are relatively accurate, they are slow because there are multiple steps involved […]
