One Clinic

One Clinic handles the majority of hospitals and health care on the islands. It has clinics in every districts on the island except old town (there used to be one, but it got robbed and it was deemed not worthy to start up again).
In a One Clinic you can get basic diagnostics done, as well as surgeries and buy medications. There are hospital beds in most of them, so people can stay a few nights if they need. Not all clinics feature all features, some are very small and only sell medication and do basic diagnostics.
One Clinic is originally from China and operates in a lot of large cities all across the world. It got so big by buying out a lot of the competition with massive offers. It is rumoured to be funded by the Chinese government.
One Clinic is often criticized for it's high prices and quick turn around of patients (unless you pay up handsomely).
