The most effective protection from personal contamination is ensuring strict attention to personal hygiene and in particular, frequent and thorough hand washing with soap and water and refraining from hand-to-mouth contact. Colds and other viruses can spread quickly in an enclosed area such as a ship. Continue to practice common-sense hygiene and respiratory courtesy. Wash your hands often and cover your coughs and sneeze. It is recommended that passengers carry anti-bacterial hand sanitizer, which does not require rinsing with water. Use sanitizer frequently and throughout the day, particularly after shore excursions and prior to meals. If you have any questions regarding your health or safety, please do not hesitate to ask your cruise director.
