A system for administering a treatment to individuals infected with a virus such as hepatitis. The system includes an enclosure and at least one gas supply that is used to create an altered atmospheric environment within the enclosure. The patients walk into the enclosure, the super-atmospheric environment is created with the gas, and the patients remain in the super-atmospheric environment for a predefined length of time. The individuals are subsequently returned at a safe rate to normal atmospheric pressure. The treatment can be repeated daily, monthly or annually depending on the needs of the patient. The system includes a control unit that stores and runs at least one treatment program that helps determine treatment variables such as amount of pressure, length of time and the type of gas or gases. It is believed that the present viral treatment may be able to be used in combination with medications and other viral treatments.
