U.S. Doctor Cured of Ebola Says He'll Return to Liberia
Dr. Richard Sacra, a Massachusetts physician who was cured of Ebola earlier this year after contracting it in Liberia, says he will return to the West African country to resume working in a clinic there.
Sacra spent weeks at a treatment center in Omaha, Neb., and was released back home on Sept. 25. He is one of 10 people treated for Ebola in the United States.
He spoke about his plans after a Tuesday news conference at the Massachusetts Statehouse, following an announcement of a $1 million grant to help speed the development of a faster, better test for Ebola infection.
According to the Associated Press, Sacra said that he "feels great" and physicians say his brush with Ebola has effectively rendered him immune to the disease.
Sacra is a faculty member at the University of Massachusetts Medical School and has worked in Liberia for more than two decades, AP reported. He said he plans to resume work at Eternal Love Winning Africa (ELWA) hospital in the Liberian capital of Monrovia. The clinic was founded by the North Carolina-based charity SIM.
According to the World Health Organization, there have been almost 18,500 cases of Ebola in West Africa in the current outbreak, including almost 6,900 deaths.

U.S. Teens Now More Likely to Use E-Cigarettes Than Traditional Cigarettes
The use of electronic cigarettes by American teens has surpassed their use of traditional cigarettes, according to a federal government study.
Among Grade 8 students, nearly nine percent said they'd used an e-cigarette in the last month, while four percent smoked traditional cigarettes. The rates were 16 percent and seven percent among 10th-graders and 17 percent and 14 percent among high school seniors, the Associated Press reported.
The National Institutes of Health survey of more than 41,000 students also found that between four and seven percent of teens who tried e-cigarettes had never smoked a traditional cigarette.
