The Edge: Contaminated cruise expands contact tracing to U.S.

CHARLOTTE, N.C.- A rare and potentially deadly virus is triggering a global health alert, and now U.S. officials are tracking passengers who may have been exposed at sea. Health authorities say dozens of travelers from a cruise ship tied to a Hantavirus outbreak are being monitored across multiple states, after the illness was linked to confirmed cases and deaths. In an unusual twist, officials are also investigating a possible new case involving a flight attendant who reportedly came into contact with an infected passenger. While the risk to the general public is still considered low, the international response is rapidly expanding as contact tracing spreads across borders.
