The Centers for Disease Control and Prevention says it has "established measures in place to identify and assess travelers arriving from the affected region," the area of Siberia where a laboratory worker died after a suspected plague exposure. Federal officials also say the danger to Americans is small. A Department of Health and Human Services spokesperson said only about 200 travelers from the region reach the United States in a typical year, according to ABC News.
Those travelers arrive through airports where CDC staff are already stationed. No one has been placed on the federal Do Not Board list in connection with the case, ABC reported. The CDC said it will keep monitoring and adjust its response if conditions change.
