New York: Four more American aid workers arrived back in the United States today from West Africa to be monitored for Ebola, health officials said.
The latest arrivals bring to 16 the number of aid workers who have returned in the last week from Sierra Leone. None of them have been diagnosed with Ebola, but they will be isolated and monitored during the next three weeks for signs of the disease.
Officials have released few details, citing patient privacy. But all 16 are connected to or had direct physical contact with another American who came down with Ebola last week in Africa.
He works with Partners in Health, a Boston-based international aid organization that has been treating patients in Liberia and Sierra Leone since November.
The unidentified man is in critical condition at a National Institutes of Health hospital in Bethesda, Maryland.
The other aid workers are staying near the Maryland hospital or hospitals in Atlanta and Omaha with special isolation units in case they become sick, according to officials with the Centers for Disease Control and Prevention.
Partners in Health officials did not respond to calls and emails from The Associated Press on yesterday or today. It is one of the international medical groups helping treat Ebola patients in West Africa.
The World Health Organisation estimates the virus has killed more than 10,000 people, mostly in Guinea, Liberia and Sierra Leone. While deaths have slowed dramatically in recent months, the virus appears stubbornly entrenched in parts of Guinea and Sierra Leone.
Since last summer, several US aid workers have gotten Ebola and have been flown back to the US for care. A few other individuals have returned for monitoring; none got sick.
The 16 who have returned since Friday are by far the largest group. And more may be on their way later this week, CDC spokesperson Kathy Harben said today.
It's not clear how the critically ill American was infected with the Ebola virus, which is spread through contact with a sick patient's blood or bodily fluids. He was working at a government hospital in Port Loko in western Sierra Leone.
