Interesting , isn't it? ....as there is a big difference between dying OF it, and dying WITH it. In many cases this has been put on the death certificate, but it was not necessarily the cause of death, so the figures may be way out, either way. As we now know, many had underlying health issues, and perhaps those issues were lying undiscovered until they cauģht the bug. My daughter's ex boyfriend lost his father, but he was suffering with COPD/asbestosis, so his chances were very slim and even a common cold may have been serious for him.
