Virus disease spreads effortlessly mechanically or through minute insect vectors that are extremely challenging to avoid. Emergence and reemergence of new viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), H1N1 influenza virus, avian influenza virus, dengue virus, Citrus tristeza virus, and Tomato yellow leaf curl virus have paralyzed the economy of many countries. The cure for major viral diseases is not feasible; however, early detection and surveillance of the disease can obstruct their spread. Therefore, advances in the field of virus diagnosis and the development of new point-of-care testing kits become necessary globally. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) is an emerging technology for gene editing and diagnostics development. Several rapid nucleic acid diagnostic kits have been developed and validated using Cas9, Cas12, and Cas13 proteins. This review summarizes the CRISPR/Cas-based next-generation molecular diagnostic techniques and portability of devices for field-based utilization.
