The calculated
CFR has only marginal comparative value because in many countries, excess deaths far exceed reported case fatalities which would be a better indicator of the disease impact.
IFR will not likely be known until long after the pandemic has ended. In the meantime, we mark as estimate what our computations indicate the implied
IFR may be.
We use an algorithm that is applied on the fly by a computer program and the algorithm is based on data from China and South Korea. The very specific mass testings in China and South Korea yield extraordinary
data. So also do surveys conducted by nurses in the provinces of the Philippines.
