The presentation describes the hygiene and epidemiological control in the Czech Army. This control is implemented by two organizational systems. The first of them is based on the garrison medical stations and the Central Military Medical Institute, which are the institutions built according to the military organizational tables. The second system consists of some military hygiene service officials (Chief Hygienists, Director of the CMMI, the heads of the CMMI branches), who execute their authorities derived from the Public Health Protection Act. Some details about hierarchy and main tasks of both systems are provided.
