From your link:
“The government hospital at Kenema was apparently used as part of a research project into Lassa fever sponsored by the US. It has been reported that both USAMRIID and infectious disease specialists at Tulane University were involved.
It would be nice to know what exactly they were doing, and if their research involved any gain-of-function experiments which could have affected the Ebola virus. As I understand it, some virologists believe that by experimenting with mutations that make a virus more virulent, they can produce more effective vaccines.
This approach apparently is quite controversial within the public health community, as many believe that it has the ability to generate a potential pandemic pathogen.”
Looking at the ramp up to this more virulent outbreak, the timing of these researchers “poking the bear” sure is suspiciously coincidental.
Just to be clear— that was my speculation.
The Guardian article that I linked has specifics on gain of function virus experiments.
