The 10,000 are likely to be mostly additional deaths, over and above driving casualties, 'flu sufferers etc.
We are already getting "additional death" scores here which is a sort of measure by proxy of the effect of SARS-CoV-2. There is a standard way of counting this, at least across Europe (and pre-Brexit UK!) There is of course a fair amount of variation but having COVID-19 is something to avoid if you can.
It is going to take some really funky stats to work out the real effect because there is less 'flu already in say Aus due to less travel and N hemisphere residents bringing it down south as they head into autumn/winter. Air quality is up nearly everywhere so COPD might be mitigated somewhat. Less road travel means less accidents. However suicides might be up and at least here in the UK there is a fairly well documented lack of people going to A&E (ER) when they should out, of fear or being stoic. Many other treatments have been put on hold.
SARS-CoV-2 has turned the world upside down. I do look for bright sides eg the huge social WFH experiment seems to be a huge success and opportunity. However, additional people are dying in rather unpleasant ways that they would not have done less than six months ago.
