CHICAGO (Reuters) - The Centers for Disease Control and Prevention (CDC) on Thursday warned state and local health officials about potential infections from a deadly virus previously unseen in humans that has now sickened 14 people and killed 8.

Most of the infections have occurred in the Middle East, but a new analysis of three confirmed infections in Britain suggests the virus can pass from person to person rather than from animal to humans, the CDC said in its Weekly Morbidity and Mortality Report on Thursday.
