A Data Driven Investigation on the Relationship between Tests, Confirmed Cases and Positive Rate: The Case of Greece

Abstract

While the pandemic of COVID-19 has proved a global challenge for humanity, it has also provided an unprecedented opportunity to study infectious diseases because of the globally coordinated effort to collect daily data and make it publicly available. As a result, it is possible to access data and try to improve on models and approaches. It is probably, so far, the largest effort to conduct testing on population at a global scale for an infectious disease. The aim of this project is to report on the relationship between the daily values of the test samples, the confirmed cases and the positive rate for COVID-19 in Greece. A discussion on the volatility of the reported metrics by media coverage is carried out, to highlight the potential pitfalls of using the confirmed cases or positive rate in isolation. For the case of Greece, a dependence in the number of tests and confirmed cases on the weekdays is identified. That dependence seemed to decrease with increasing number of tests. A comparison takes place between Greece and Austria which is a country with a similar size and also data regarding the RT-PCR tests and antigen tests are publicly available.
