Reproductive number

We are quantifying the spread of COVID-​19 through time in Switzerland as well as for >180 countries across the world by quantifying the reproductive number using case data and line list data. If this number is above 1, the epidemic is exponentially increasing, if this number is below 1, the epidemic is declining. 

The National COVID-19 Science Taskforce reports our estimates for Switzerland (updated daily) on their external pagewebpagecall_made. We further have a dedicated webpage to display estimates of the reproductive number for Switzerland, as well as its Cantons and Greater Regions. 

On our dedicated webpage, we provide estimates for countries around the world based on published data. For South Africa, this is a great collaboration with team of external pageProf Tulio de Oliveiracall_made. All estimates are updated daily and our code is external pageopen sourcecall_made.
