 Select a few research articles (published or preprints) of in-depth studies related to COVID-19 or other similar infectious diseases, clearly describe research questions(s), summarize and interpret the results of the popular approaches in detail using your own words. Compare approaches from different articles with detailed discussion on data analysis, statistical modeling, verification, and its relevancy to scientific goals. If possible, reproduce (a part of) what is done in the previous studies (optional). Summarize the results and have appropriate references. Interpretability is important for literature review. i.e. After reading your literature review, I will know the works in the papers your review (without reading the papers).
