Research output: Chapter in Book/Report/Conference proceedingChapter


COVID-19, the disease caused by SARS-CoV-2, was first introduced to human populations in December, 2019. There was no pre-existing population immunity and thus the disease spread rapidly throughout the globe. Since its emergence, greater population level immunity has been acquired, notably through the advent of vaccines; however, newer COVID-19 variants have also resulted in increased transmissibility.
