Articles sur R0

New COVID variants may be more transmissible but that doesn’t mean the R0 – or basic reproduction number – has increased

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

Why we corrected our estimates for the reproduction number of two COVID subvariants

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…

How contagious is Delta? How long are you infectious? Is it more deadly? A quick guide to the latest science

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.

Where coronavirus variants emerge, surges follow – new research suggests how genomic surveillance can be an early warning system

By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.

A few superspreaders transmit the majority of coronavirus cases

Epidemiological data suggests that 80% of COVID-19 cases can be traced to just 20% of those infected with SARS-CoV-2.

Coronavirus: what a second wave might look like

Getting the control measures right is critical.

Coronavirus: is the R number still useful?

R is still useful for public health, but it should not be the only metric we use to understand virus transmission.

Latest coronavirus modelling suggests Australia on track, detecting most cases – but we must keep going

The latest Doherty Institute modelling also indicates the spectre of ‘unidentified community transmission’ is very unlikely indeed.

In Depth Out Loud podcast: how to model a pandemic

An audio version of an in depth article on why mathematical modelling is crucial to understanding pandemics like the new coronavirus.

R0: How scientists quantify the intensity of an outbreak like coronavirus and predict the pandemic’s spread

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.

A clue to stopping coronavirus: Knowing how viruses adapt from animals to humans

Some of the world’s worst diseases have come from animals. Bats, cows, camels and horses have all contributed. Now, scientists are working to know which animal introduced the new coronavirus.
