You must be reading a different source than linked, because I read that it is a husband and wife with the wife exhibiting symptoms. They’re stuck on the ship’s tender between the cruise liner and land because neither will allow them entry. There’s an air ambulance awaiting at the airport in Belize but they can’t get to it.
That’s what the linked report says. What have you read differently?
“Updated: The State Department confirmed this morning that a health worker who may have handled lab specimens from the man who died of Ebola in Texas is on board a cruise ship apparently in the Caribbean. The employee, who has demonstrated no symptoms of Ebola, is self-monitoring, according to a State Department spokeswoman.”
He may have handled a lab specimen or he may not have handled a lab specimen.
He has no symptoms.
