It’s hard to say to what extent she was presenting. That all five picked it up sets off alarm bells, for sure. That’s pretty efficient.
I would be delighted to be wrong.
What is irrefutable is that this is NOT Zaire. The incubation period alone is all the evidence one requires to establish that as a fact. This is a mutated strain of Ebola. Reston provided evidence that Ebola could mutate such that aerosolization of the virus could transmit the disease. In fact, Reston was so efficient that it migrated through the air ducts and killed all the monkeys from a Friday evening to a Monday morning. They all died within a weekend. It was Sunday night that the CDC carted off the dead monkeys and shut down the facility, and Preston marveled at the CDC’s dumb luck in all of that.
I pray you are wrong. I suspect you may not be.
Zaire is the causative agent, but it appears that this is a new strain and it has evolved in parallel.
In March 2014, the World Health Organization was notified of an outbreak of a communicable disease characterized by fever, severe diarrhea, vomiting, and a high fatality rate in Guinea. Virologic investigation identified Zaire ebolavirus (EBOV) as the causative agent. Full-length genome sequencing and phylogenetic analysis showed that EBOV from Guinea forms a separate clade in relationship to the known EBOV strains from the Democratic Republic of Congo and Gabon. Epidemiologic investigation linked the laboratory-confirmed cases with the presumed first fatality of the outbreak in December 2013. This study demonstrates the emergence of a new EBOV strain in Guinea.

Phylogenetic analysis of the full-length sequences established a separate clade for the Guinean EBOV strain in sister relationship with other known EBOV strains. This suggests that the EBOV strain from Guinea has evolved in parallel with the strains from the Democratic Republic of Congo and Gabon from a recent ancestor and has not been introduced from the latter countries into Guinea.
