The Nazi 'final solution' began with the medical scientists and doctors. First came the frail, infirm, and mentally-physically challenged. Their deaths and disposal were studied and optimised. Next came the closed boxes mounted on vehicles using exhaust fumes. Then the first extermination camps using tank engine exhaust fumes. Later camps used faster gas-based methods Zyklon B - a soil fumigant. Cremation on a 24/7 basis for the bodies.

There was a fictional TV series in the UK some years ago which explored mass deaths and disposal (incinerators), due to an unknown cause.

Enter now the 'elegant' health solutions.

WHO could have seen it coming?
