The pattern of past Ebola outbreaks is indicative of an effective reproductive ratio of less than 1, which can lead to the generation of a range of outbreak sizes consistent with the scale of the ongoing epidemic.

Patient outcomes, and the time spent by patients during hospital admission, showed considerable variation over the first year of the COVID-19 pandemic.

Model-inference reconstructed SARS-CoV-2 transmission dynamics in South Africa during March 2020 to February 2022, and quantified the immune erosion potential and transmissibility of three major variants (Beta, Delta, and Omicron), highlighting their common characteristics and the need for more proactive preparedness.

A real-time genomic surveillance approach based on mutation analysis of SARS-CoV-2 proteins has enabled a priori prediction of surge in number of COVID19 infection cases, including those already observed in July and September 2022.

Combined analyses of publicly available population-level variant data and detailed individual-level clinical data can be used to quantify the clinical impact of new SARS-CoV-2 variants in different settings.

An analysis of Australian case data demonstrates how the combined strategy of border measures, case targeted interventions, and social distancing effectively contained the first epidemic wave of COVID-19.

Vaccination activities that occurred before the COVID-19 pandemic, 2000-2019, are estimated to avert 50 million deaths, highlighting the enormous benefits of continued and improving vaccination.

Selection bias, also known as collider bias, likely explains the apparent protective effect of G6PD deficiency against cerebral falciparum malaria.

Prevention and antivenom treatment could reduce snakebite deaths, which killed 1.2 million Indians from 2000-2019, about 70% of which occurred in eight states, and half during four rainy months.

Key numbers about the biology of the SARS-CoV-2 virus and the infection of a single human host by the virus have been compiled from the peer-reviewed literature.
