Caduceus International (カドゥケウス機関 kadukeusu kikan) is an arm of the World Health Organization. Starting in the 1980s, Caduceus' mission is the research and application of cures to diseases, by 2018, Caduceus had found a cure for cancer, AIDS and the TFTA influenza.

It is at the forefront of countering emerging diseases. Working for the betterment of people's health, it is known for its medical prominent achievement. Although it has been the subjugation of terrorist attacks, the swift action taken by Caduceus and its doctors thwarted both terrorism and disease released by them.


Caduceus is divided into several branches across the globe, including the Caduceus USA, Caduceus Europe, and Caduceus Japan.

Caduceus USA Edit

Caduceus USA is the North American branch of Caduceus. Due to localization conflicts, two versions of the same organizations appear in the series.

The discrepancy between the branch's depiction in Under the Knife/Second Opinion and New Blood is because the original setting of Under the Knife/Second Opinion was Japan, which was changed to USA by the English localization.

Under the Knife/Second Opinion/Under the Knife 2Edit

Caduceus Europe Edit

Caduceus Europe is the European branch of Caduceus. They have assisted Caduceus USA on many missions, including the Africa mission and the Delphi Headquarters raid. Caduceus Europe is based in the United Kingdom.

Caduceus Japan Edit

Caduceus Japan is the Japanese branch of Caduceus.

In Trauma Center: New Blood , Derek Stiles and Angie Thompson are mentioned to be from Caduceus Japan, when in the other games, they are said to be from Caduceus USA. This inconsistency is due to localization, although Derek and Angie's transfer is hinted at at the end of Under the Knife 2.
