The incubation period is around 21 days. Dr. Spencer did not show symptoms until 9 days after exposure. (10/12 exposure, 10/21 symptoms). Hickox has been in the U.S. 5 days. Did she have any exposure in the 4-12 days prior to her arrival here?
42 days covers 98%
When it comes to as deadly an infection as 0bola and a country of 330,000,000 peeps, 98% isn't NEARLY enough certainty.
Part of her original story was how she had been caring for a poor girl who was in siezures due to the fever of ebola and how she was the only person caring for her and she died from the disease. This was the beginning of all part of her emotional stress of returning stateside then being put in isolation against her will.
If I was the governor of Maine I would have her house surrounded by armed reservists just returned from the $hit with orders for them to shoot her if she tryed to leave the proeerty.
