Dr Thongchai Keeratihattayakorn , deputy permanent secretary for public health , said at the Public Health Ministry in Nonthaburi in the afternoon that the hacked information was not in the primary database the hospital used to provide public services , and the hospital continued to operate as normal . The details were in files stored on a separate server used by hospital staff in their daily tasks , he said .
