One scientist may have been exposed to the Ebola virus and as many as a dozen others are being assessed for potential exposure at a lab of the Centers for Disease Control and Prevention in Atlanta, agency officials said Wednesday.
The potential exposure took place Monday when scientists conducting research on the virus at a high-security lab mistakenly transferred a sample containing the potentially infectious virus to another CDC lab in same building.
The technician has no symptoms of illness and is being monitored for 21 days. Agency officials said others who entered the lab have been contacted, and based on assessments, it’s likely no one else was exposed. They said the number of people who entered the lab could be as many as a dozen, but more likely far fewer.
