The author of the Lancet article acknowledges that the speed with which cv has killed a lot of people already shows it may be a different animal to those flu pandemics. Being wary of it is not just a sign of being too risk averse, or of having been pushed into worrying by the press. It is its own thing, a new disease with effects we're only just learning about. This is the one we have to deal with, not another flu.
"There was no panic in 1957 and 1968, runs this argument, so why the panic today?"
"However, critics of the UK Government's response are perhaps right to point to the role of epidemiology and statistical modelling in propagating fear."
In both of those quotes from the Lancet article the author uses the words 'panic' and 'fear' to imply that actions taken today are unnecessary and driven by emotion, rather than just different actions driven by different rationales and circumstances (that can then be agreed with or disagreed with on their own merits).
Have people worried about lockdown going on too long just been driven to panic about the economy by reading the Daily Telegraph? Or are their concerns valid?
People referring to actions they don't see as necessary as evidence of 'panic' comes up over and over again at the moment. There's a whole space in which we could discuss coronavirus measures as worth doing or not based on all sorts of reasons, so it's a shame the argument often seems to end up unhelpfully reduced to accusations of panic.
