The ongoing Wuhan virus hysteria is immensely frustrating to those trying to understand and think clearly, because the information available is incomplete, the key question (how lethal is it?) is unanswered and the vast majority of media coverage and “analysis” so infantile and innumerate.
It would appear that Real Clear Politics has taken to publishing a daily death rate by country, using diagnosed cases as the numerator. But testing penetration of populations varies by country, and everywhere is heavily weighted to the very sick, missing completely the possibly huge number of Wuhan positives who are only slightly ill or have no symptoms at all. A death rate based on that numerator is grossly misleading in an alarmist direction.
Potentially further calling into question the value of the published numbers is that there are apparently no international standards for when a death should be attributed to the Wuhan virus. In Germany, it appears that they are strict — i.e., death must have been caused by the viral flu, not the underlying condition that put the usually elderly person at high risk. To some extent, at least, this may account for Germany’s extraordinarily low death rate, even employing its known cases as numerator.
Italy, on the other hand, may be inadvertently inflating its death numbers by including virtually all deaths in Wuhan-positive persons in their total, regardless of apparent actual cause. There is some evidence that Italy performs postmortem Wuhan tests, and if the body tests positive, the death is attributed to the virus — though, in fact, the (e.g.) 87-year-old who had been suffering from heart failure for months was carried off by his underlying, largely age-related frailty.
