Hi. I& #39;m @Ashley_J_Kirk, senior data journalist at The @Telegraph.

We& #39;ve had some questions about #COVID19 data from our readers, which I& #39;ve done my best to answer.

Q: Is Chris Whitty correct to say that the UK death rate is less than 1%?

The UK has recorded 55,242 #coronavirus cases and 6,159 deaths.

This gives us a case fatality rate of 11.1% - higher than Chris Whitty’s 1%, and the 3.4 per cent case fatality rate that WHO has published

While there are just over 55,000 recorded cases in the country, the real number of infections is likely to be far higher - with many experts expecting it to already be well over a million. #COVIDー19

Q: Why don’t you use a three-day cases average, instead of the number of new cases on each day, when presenting coronavirus trends? #COVIDー19

@Ashley_J_Kirk responds https://abs.twimg.com/emoji/v2/... draggable="false" alt="👇" title="Down pointing backhand index" aria-label="Emoji: Down pointing backhand index">

On our Coronavirus Live Tracker, our trajectories line chart - which can be used to compare different countries’ deaths - now takes the average number of deaths across the last seven days for any one country.

This irons out any day-to-day fluctuations

Q: To what extent can we compare the data between different countries?

@Ashley_J_Kirk says: There’s no easy answer to this, but we definitely do need to take care when comparing different countries.

There are lots of reasons for this, but I’m going to outline three #COVIDー19

Why we need to take care when comparing different countries:

https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle"> Each country has a different demographic profile

https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle"> Different countries are testing their populations at different rates

The data that we have is the best we’ve got.

So yes, we can compare them - but we have to be aware of the caveats.
