Mitigation measures are being put in place to minimise the risk of COVID-19 onboard a submarine and to maintain the health and wellbeing of their ships' companies. The Submarine Service is following Public Health England (PHE) guidelines where practical for all personnel and, to reduce the risk of transmission, further emphasis is being placed on the cleaning of communal areas and personal hygiene. Measures have been introduced prior to sailing which involve the whole ship's company quarantining onboard the submarine. In addition, personnel who are, or whose households are, symptomatic will be isolated before embarking, in accordance with PHE self-isolation guidelines.
Any individual who experiences symptoms while at sea will isolate onboard in accordance with PHE guidelines and receive the appropriate medical attention, until either recovery is established or they can be safely removed and returned to shore.
