As Covid-19 is a newly emerging disease, much is still unknown about its severity. This page lists all our work on the severity of Covid-19.
Status:
Using globally available data sources with mathematical models, we analysed the transmissibility and severity of a novel SARS-CoV-2 variant, 501Y.V2, in South Africa.
We estimated the contribution of asymptomatic individuals in spreading COVID-19.
The risk of severe COVID-19 disease is known to be higher in older individuals and those with underlying health conditions. Understanding the number of individuals at increased risk of severe COVID-19 illness, and how this varies between countries is needed to inform the design of possible strategies to shield those at highest risk. We evaluated the global prevalence of underlying conditions associated with severe COVID-19 disease.
We used critical care admissions in the United Kingdom to evaluate the number of cases and rate of spread for COVID-19 prior to the lockdown on 23 March 2020
Adjusting for delay from confirmation-to-death, we estimated case and infection fatality ratios (CFR, IFR) for COVID-19 on the Diamond Princess ship
