PP: I was not highly paid at WHO and didn't give advice to governments. I did things like establish satellite communications in Darfur & in the aftermath of the 2004 Tsunami. (We found that it's well-nigh impossible to help in a disaster situation if you can't communicate with the people on the ground.) In my job, I visited over 40 countries, usually the Ministry of Health, setting up computer & communication systems, so have some idea of Public Health and how it works (or, more often, doesn't work). I also ran the WHO website for a while in the early days, dealing with a variety of specialists such as epidemiologists.
As for white lies, there's no lie in saying that the current UK death rate is approximately 1 per day per 10 million population. If I were being pedantic, I would call suggesting otherwise to be a mathematical non sequitur.
Naturally, different people see KPIs differently. My argument is simply that the case rate is misleading as a KPI because it doesn't have the societal consequences that the Death Rate & the hospital bed occupancy rate have. It can't be denied that those rates have fallen massively in the last 3 months despite the Case rate (roughly) tripling.
Just as a matter of interest- Did any Porton people go on the recent WHO mission to Wuhan? They must know as much about this field as anyone on the planet. Actually, forget it, it's probably subject to the Official Secrets Act.
