The modern world, with ease of travel, large gatherings of people and broadened social networks, has demonstrated that the spread of viruses can be fast, dangerous and almost impossible to detect. The recent spread of the SARS-CoV-2 causing the COVID-19 pandemic has demonstrated the power and ease to which viruses can spread throughout, not just individual communities, but the globe.
Whilst a variety of testing options have become widely available, including rapid testing for basic screening of SARS-CoV-2 virus via immunoassays and polymerase chain reaction (PCR) and antibody testing for the presence of antibodies and assessment of current immunity ,there has been no test to assess infectivity and whether an individual is carrying and passing live active viral particles or if viral particles are present in an environment.
Checking for symptoms and contract tracing have proven to be inadequate to contain the spread of SARS-CoV-2 leaving all people vulnerable and causing the need to close down entire cities creating medical, social and economic havoc. GreyScan TVD-1 and TVD-2 change the ability to test people and places with quick, unobtrusive and accurate virus detection to help safeguard the world in real time.
