To achieve effective surveillance, rapid screening techniques are essential to detect and prevent the spread of SARS-CoV-2 in the environment. The integration of isothermal amplification with the CRISPR-Cas system, coupled with advancements in amplification-free technologies, has revolutionized the direct visual detection of environmental viruses at testing sites.
