Okay, just because you think you know it all, doesn’t mean you should post about it on social media for the world to see. This person seemed pretty frustrated that the WHO wasn’t doing much work other than collecting data. Sure, that’s probably a big part of their job but a simple Google search would have revealed how much more they’ve actually done.
From eradicating smallpox to nearly eradicating polio, and developing an Ebola vaccine, it’s not only about collecting data at the WHO. Dr. Karl knows that and he wasn’t about to let the OP get away that easily. Again, just spending a few minutes looking it up would have saved them from public embarrassment.
