As ready as you are to be done with COVID-19, it’s not going anywhere soon. A historian of disease describes how once a pathogen emerges, it’s usually here to stay.
The focus, for some time, has been on new daily case numbers. But what if we are looking at the wrong figure? We should focus on the average number of cases “under investigation” over the last 14 days.
A preliminary study published online this week estimates Australia had 60,000 undiagnosed COVID-19 infections by July. But there are a range of limitations to the study.
The pandemic has exposed many of us to new statistical concepts, on the news, in everyday conversations and on social media. But how many are you getting wrong?
