Mathematics of the COVID-19 Pandemics: Lessons Learned and How to Mitigate the Next One

" summary

Simple compartmental SEIR-style models with added pre-symptomatic and asymptomatic classes are fit to mortality data (not case counts) and show pre-symptomatic/asymptomatic transmission explains roughly 50–70% of early spread. Early lockdowns one–two weeks sooner or high N95 adoption (80%+) would cut deaths dramatically; delayed reopening fuels huge second waves. Vaccination reduces Rc by (1 − εv fv) and sets a herd threshold; genomic surveillance, random testing, and stockpile N95s plus free rapid home tests and fit-to-mortality model fitting are the concrete, effective actions proposed.
