Just because a variant spreads faster, it doesn’t necessarily mean it has a higher R0.
Articles on R0 number

We published an article earlier this month that contained incorrect estimates for the basic reproduction number (R0) for COVID subvariants BA.4/BA.5 and BA.2. We have now corrected the error, but I wanted…
Delta is more contagious and appears to be more deadly. And it’s more likely to land those infected in hospital and intensive care. Here’s what the latest evidence says about the dominant variant.
By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.
It’s quite likely this virus will never be eliminated from the world. But even so, getting vaccinated enormously reduces your risk of severe outcomes like hospitalisation and death.
Epidemiological data suggests that 80% of COVID-19 cases can be traced to just 20% of those infected with SARS-CoV-2.
The latest Doherty Institute modelling also indicates the spectre of ‘unidentified community transmission’ is very unlikely indeed.
I’m here to say: make sure you read beyond the headlines.
Epidemiologists want to quickly identify any emerging disease’s potential to spread far and wide. Dependent on a number of factors, this R0 number helps them figure that out and plan accordingly.
