Abstract

This article encompasses a review of the limitations of the current methods used for the detection of SARS CoV-2 (the virus responsible for COVID-19) at airports across the globe. These methods involve the screening for vital signs and symptoms, including thermal scanning, heart rate and breathing capabilities. From the impact of COVID-19, other pathogens could be exploited as potential weapons (bioweapons) against civil aviation. Bioagents such as viruses, bacteria, fungi, and toxins, have been used by the military and terrorists in conflicts to cause mass casualties, death, panic, and disruptions. In this review, focus is on the development of biosensor detection system that will address the limitations of the current measures being employed to detect pathogens. Biosensor detection system offers real-time, specific, sensitive, and a cost-effective means of detection of bioweapons at airports.
