Western University in London, Ont., has created a new tool that they say will help provincial and national policymakers make decisions on which of the “near-endless stream” of contact-tracing apps to utilize.Public health officials use contact-tracing, or CT, as part of efforts to limit the spread of infectious diseases, like COVID-19, by identifying and subsequently isolating close contacts of a confirmed case to help “break the chain of human-to-human transmission,” Western University says.
Why contact tracing becomes ‘impossible’ as coronavirus cases surge It’s historically been a largely manual process but “a myriad of smartphone-based” apps have been created since the novel coronavirus pandemic began to speed up the process, though.
