CDC warns cruise passengers after hot tubs linked to Legionnaires’ outbreaks
The CDC is alerting travelers about the risk of Legionnaires’ disease from private hot tubs on cruise ship balconies. Investigations linked two separate outbreaks to in-cabin whirlpools that weren’t disinfected as rigorously as the public spa areas. With reported cases requiring hospitalization, major cruise lines are now revising cleaning protocols.
What this means for you:
If you’re booking a cruise, ask how private hot tubs are maintained; confirm they follow strict sanitation standards.
Consider bringing test strips to check disinfectant levels before using any personal whirlpool.
Stay alert to respiratory symptoms post-cruise; consult a doctor if you suspect possible infection.

Key Entities

Centers for Disease Control and Prevention (CDC): A U.S. federal health agency established in 1946, overseeing disease prevention and public health. It regularly issues guidelines to protect travelers from outbreak risks.
Cruise Lines: International shipping and tourism companies operating ocean liners. Many are adopting new cleaning protocols for private onboard amenities.
