In some cases, a patient may display symptoms of a disease, which is highly contagious. These diseases may be airborne or spread by contact. To prevent infection of the remainder of the crew or other patients, an Isolation Ward segregates these types of patients. Designed to handle up to six patients with completely different disease manifestations, each isolation chamber can be programmed for a wide variety of atmospheric and gravity requirements should the particular disease warrant a change from normal shipboard conditions in preparation for transport to a facility that can better handle their case.

No one can enter an isolation chamber in the ward without the appropriate code entered into the chamber door control panel. An attempt at unauthorized entrance causes the ward to be sealed and an alarm to be sounded in both the CMOs Office and the Security Duty Office.
