The outbreak of novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-induced disease, COVID-19, spread rapidly from Wuhan, China, in December 2019. This led to China experiencing a major public health emergency with over 83,000 confirmed cases and 4634 deaths as of June 2020 (Rai et al., 2020). Although there are a few newly developed vaccines and treatments, it is conceivable that without some impact on transmission, the virus will continue to circulate, infect, and cause serious disease, in certain segments of the unvaccinated population.
