The use of Covid-19 contact tracing applications has become almost irrelevant now that several flavors of Covid-19 vaccine have been developed and are constantly being distributed to people during the pandemic to help alleviate the need for lockdowns. Also, the availability of at-home testing kits and testing sites means that people do not need to contact trace as much since individuals can get tested and follow the health guidelines in ensuring their health and the safety of others around them. Nevertheless, governments around the world are still faced with the Covid-19 pandemic challenge because the virus is not yet controlled due to the different variants and the rapid contamination rate that outpaced the logistic supply chain processes in the distribution of the vaccines and the time it takes in convincing individuals to take the vaccine swiftly to reach herd immunity. Therefore, the current pressing need is that of addressing the infection rate by finding ways and solutions to minimize or slow down contamination among people especially with the increased number of variants. This paper is an extension of the "COVIDFREE App: The User-Enabling Contact Prevention Application" work originally presented in 2020 IEEE International Symposium on Technology and Society (ISTAS) conference that provided a smartphone application architecture with the goal of proactively enabling users to avoid encountering infected Covid-19 patients. This paper elucidates and discusses additional concerns not thoroughly addressed previously regarding the vaccines, booster, and infection rates, and demonstrates the feasibility of the proposed architecture with a web application prototype. This paper also discusses the benefits of funding and developing contact tracing and prevention applications, such as the COVIDFREE App, to provide the needed ingredient in reducing the infection rate and provide citizens the needed preparedness and relief in actively fighting the virus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
