When dealing with figures you have to realise a couple of things.
NO ONE knows how many cases.
NO ONE knows how many are infected.
NO ONE knows how many deaths are attributable to COVID -19.
All figures are gathered from different country's different methods.
No two countries have to same stats gathering regimes
No two countries have the same testing regimes.
No two countries have the same levels of penetration of testing nor protocols.
The stats are gathered from a mediocre number of tests which have at least two main differences either presence of the virus itself, or presence of antibodies.
Not all who have died of COVID 19 have been tested.
Not all who have been infected have been tested
Not all who have recovered have been tested.
Some health services, such as the USA, where there are millions uninsured, and at least half a million homeless may well die of COVID=19 and NEVER become a statistic.
Where testing is patchy people dying of respiratory illness may well be attributed to COVID-19 when they have died of something else.
It is probably more likely that the differential number are less to do with the virus and the host country's vulnerabilities, and more to do with the degree and accuracy of testing.
I can't wait for the cheap nationalistic conclusions of most of the idiots on the Forum when comparing the gross numbers.
It's worth adding that the virus is mutating all the time. Only a tiny number of these mutations will be viable, and fewer still will produce a dangerous difference.
When looking at the numbers we could also be looking at slightly different strains emerging.
There is other evidence that is now looking into susceptibility due to the drug regime of patients; those with high blood pressure are more contraindicated with ACE inhibitors and Beta Blockers than those taking Calcium channel blockers. The common prescription regime in different countries could offer some idea of differences in fatality.

IF the results from China are any thing to go by, then more and stricter lockdown is necessary.
But can they be trusted at all?
