According to Sanja Gupta on CNN right now,
Nina Pham, when she called in, had a lower than 101.5 temperature.
On the CDC website says: Fever (greater than 38.6°C or 101.5°F)
I remember some talking head saying yesterday, that we must be over the hump because no one has contracted the disease (except Ms. Pham) since the index patient died during the span of time when it was likely to occur.
Also Gupta said that she had other symptoms of Ebola, though not the fever.
Remember the virus is building and shedding by coughing, sweating, peeing, vomiting etc.
