Spain's Ebola patient zero is a nurse's assistant.
No one can say she kept mum about the fact that she'd been near an Ebola patient recently. Authorities were well aware of her exposure, because she was on the team that cared for a Spanish missionary and a Spanish priest, both of whom were shipped back to Spain after they contracted Ebola in Africa. Both of them have died.
But although health workers in Dallas did not originally know that America's patient zero, Thomas Duncan, had been recently exposed to Ebola, there is a similarity between the unnamed nurse's disease trajectory and that of Duncan. As with him, there also was a delay in her hospitalization and diagnosis. She is said to have reported her first symptom, a fever, on September 30, and yet she was only hospitalized this week. Since authorities knew in advance that she'd been exposed, why the delay, which put many more people at risk? Should they not have erred on the side of caution?
There are various possibilities. Perhaps the authorities had such faith in their isolation and protection techniques that they thought it impossible that a health worker could contract Ebola while working under state-of-the-art conditions in a Western hospital, as opposed to in Africa. Or perhaps (as I'm beginning to suspect) the diagnostic criteria for Ebola aren't rigorous enough.
One of the first symptoms of Ebola is a fever, defined as above 101.5. But see this [emphasis mine]:
