ANNEX 1 ENVIRONMENTAL CLEANING FOLLOWING A SUSPECTED CASE OF COVID-19 IN A PLACE OF DETENTION* Infection prevention and control (IPC) measures are essential to reduce the risk of transmission of infection in prisons and other places of detention. Environmental cleaning of health-care rooms, or cells, where a suspected case has been managed is an essential intervention to control infection as well as to enable facilities to be put back into use quickly. Once a possible case has been transferred from the prison or detention setting, the room where the patient was placed should not be used, the room door should remain shut, with windows opened and the air conditioning switched off (if relevant), until it has been cleaned with detergent and disinfectant. Once this process has been completed, the room can be put back in use immediately. Preparation The responsible person undertaking the cleaning with detergent and disinfectant should be familiar with these processes and procedures: • collect all cleaning equipment and clinical waste bags before entering the room • dispose of any cloths and mop heads as single-use items • perform hand hygiene, then put on a disposable plastic apron and gloves. On entering the room • keep the door closed with windows open to improve airflow and ventilation while using detergent and disinfection products • bag all items that have been used for the care of the patient as clinical waste – for example, contents of the waste bin and any consumables that cannot be cleaned with detergent and disinfectant • remove any fabric curtains or screens or bed linen and bag as infectious linen • close any sharps containers, wiping the surfaces with either a combined detergent/disinfectant solution with a virucidal label claim, or a neutral-purpose detergent followed by disinfection with a virucidal product that has been approved for use in the facility. Cleaning process Use disposable cloths/paper roll/disposable mop heads to clean and disinfect all hard surfaces/floor/chairs/ door handles/reusable non-invasive care equipment/sanitary fittings in the room, following one of the two options below: • either use a combined detergent/disinfectant solution with a virucidal label claim • or use a neutral-purpose detergent, followed by a virucidal disinfectant approved by the prison authority. Follow manufacturer’s instructions for dilution, application and contact times for all detergents and disinfectants. Any cloths and mop heads used must be disposed of as single-use items. * COVID-19: interim guidance for primary care (updated 25 February 2020).
