There may be thousands of people who caught this disease who never knew they were actually ill, or who shrugged off mild symptoms as something else. There may be thousands of others in non-quarantined areas who didn't report themselves sick for fear of being locked down for weeks. The vast majority of such untraced people will be better by now, and they were never included in any counts. What I'm thinking is that figures for death rates are not very reliable. The fact that different regions seem to have different death rates seems to reinforce this. In addition, death rate numbers for areas with cases in the low hundreds or fewer would be intrinsically unreliable ("sample size" too small and possibly unrepresentative of the population). If a hundred people round here tested positive, but 15 were in a old people's home, and twelve of them died, to invent a hypothetical example...

So I have a feeling that the true death rate could be a fair bit lower than is currently being reported. End of optimistic musings...
