What they’re saying

“(Outbreaks are) often taking place within the community, and oftentimes we don't know that they're happening. Really, when we have these areas where people … are in really close contact, things like day care facilities, nursing homes and cruise ships, it's more likely (to be) diagnosed, reported and brought to our attention.”

— Sarah R. Michaels, Assistant Professor, Tulane University's Celia Scott Weatherhead School of Public Health and Tropical Medicine

What’s next

Oceania Cruises and the CDC will continue to investigate the cause of the gastrointestinal illness outbreak on the Oceania Insignia cruise.
