Brantly’s family had been with him in Liberia, according to the Centers for Disease Control and Prevention, but left for the United States before he became symptomatic; as such it is highly unlikely that they caught the virus from him. Out of an abundance of caution they are on a 21-day fever watch, the CDC said.
Nancy Writebol from Charlotte, North Carolina, has also been infected. She is employed by Serving in Mission, or SIM, and had teamed up with the staff from Samaritan’s Purse to help fight the Ebola outbreak in Monrovia when she got sick. She, too, is undergoing treatment.
It is believed one of the local staff was infected with Ebola and came to work with the virus on Monday and Tuesday, Isaacs told CNN. “We think it was in the scrub-down area where the disease was passed to both Nancy and Kent,” he said. That staff member died on Thursday.
Dr. Brantly is a doctor with obvious experience in diagnosing Ebola cases. Yet, he was unable to detect infection in the co-worker who infected both him and Mrs. Writebol. Further, the co-worker was able to function for two days while still being able to infect at least two other people.
This suggests that we are indeed dealing with a “New Ebola” (as Pixie has put it at PFI Forum). This New Ebola apparently leaves people well enough, while they are infectious, to both travel and work without being detected. This makes this new Ebola pandemic-capable.
