  With COVID-19 disrupting operations across various sectors of the workforce
(e.g., offices, airports, libraries, schools), preventative measures enabling
resumption of work are quickly becoming a necessity. In this paper, we present
the need for Vitals Screening Techniques (VIST) where more than one vital is
screened to ensure the safety of the population (e.g. temperature, heart rate,
and blood oxygen levels). VIST can be deployed in crowded environments to
provide the new necessary layer of safety. We provide extensive coverage of
state-of-art technology that can assist in tackling this emerging problem, and
evaluate one of the existing products on the market that employ VIST.
