Methods of supervising quarantined people In group quarantine facilities, supervision over quarantined people to ensure they do not leave the facility was exercised by police officers who carried out ad hoc inspections. In addition, in most facilities such supervision was exercised by the personnel employed at the facility, or designated by the owner of the facility or by the authority that established the quarantine facility. Supervision was exercised by staff remaining within the facility or maintaining telephone contacts with those in quarantine. County governors also reported cases where a dedicated employee was contracted to supervise the quarantine facility441. Sometimes, security companies were also employed to ensure security and order in the quarantine facilities442, or those tasks were assigned to Fire Brigades443, Municipal Police444, Military Police445, soldiers of Territorial Defence Forces446 and soldiers from individual military units447. Epidemiological surveillance was carried out by employees of the County Sanitary and Epidemiological Service Stations. In addition, most facilities were covered by video surveillance (by remote systems, and in some cases by internal systems)448. 440 County Office of Wąbrzeźno.
