Caldean Acute Cardiopulmonary Syndrome

Caldean Acute Cardiopulmonary Syndrome, or CACS for short, is a disease affecting the cardiopulmonary system of the person infected. Advanced scans or transporter's biofilters can pick up infected persons not showing signs or symptoms of the disease (the early stages).

In later stages, CACS causes the cardiovascular and respiratory systems to gradually fail, leading a cascading systems failure, leading to cardiac arrest and death. A cruel disease, CACS also has been known to cause heart failure only to revive the ill person for more suffering.

CACS is a disease native to Caldea IV. On an earlier Starfleet expedition to the colony there, an officer was infected and spread the disease to most colonists, decimating the colony's population. With the biofilters active on the ship, transporters deflected the officer's signal to a derelict supply station in orbit, where, approximately 12 weeks later, he died.

In 2372, Captain Noel Turner was infected with a variant of CACS, and, like his predecessor, his transporter signal was transferred to the supply station. Cantabrian Drs. Marie and Helena Bourget successfully found a treatment to counter the variant, leading to Turner's successful recovery. (: "Isolation")
