Two CDC officials told reporters the hantavirus outbreak linked to a cruise ship poses low risk to the general public, according to STAT News. Said David Fitter, the agency's incident manager: "CDC activated our emergency response in Atlanta immediately and has more than 100 staff actively working on this response. Operationally, we've been engaged at every step." A CDC team deployed to Nebraska is monitoring exposed passengers for 42 days starting May 11, matching the virus's incubation period.
