SARS-CoV-2

Within-host viral dynamics (together with virologists)
We have studied the effect of different antiviral drugs and their potential effect on the within-host dynamics of SARS-CoV-2 if taking prophylactically. We find that with our model, already a reduced efficacy of 70-80% of a drug can successfully prevent or delay the establishment of a viral infection within a host.

A unifying limit equation to describe the epidemiological evolution of SARS-CoV-2 (together with the SMILE-group at Collège de France)
We have derived a one-dimensional partial differential equation that can be used to describe any epidemiological model by its age distribution (the age of an infection within a host). Labeling the states according to the transitions of the epidemiological model (e.g. from susceptible to symptomatic infectious) then gives an accurate description of the population composition.

Years of life lost due to COVID-19 (together with Marius Rubo)
We have written a commentary to the published paper “COVID-19 — exploring the implications of long-term condition type and extent of multimorbidity on years of life lost: a modelling study” to clarify that the used measure “years of life lost” can not be taken at face value. The statistic is a biased measure in the sense that even a random death, i.e. a death without any specified reason, will result in 9 years of life lost by the standard life expectancy table. Therefore, the message that COVID-19 results in 13 years of life lost is misleading, which we clarify in our statement.
