Introduction: Warships have unique built environment with an ideal setting for rapid transmission of several air-borne pathogens. A study of SARS-CoV-2 behavior on board ships achieved through high rates of testing with combinations of epidemiology, transmission, ventilation, and accommodation parameters suggests inevitability of outbreaks.
Materials and methods: We propose a model based on the study of ventilation patterns and air-conditioning systems on warships which permits division of ship's crew into multiple small cohorts, named as `Space Cohorts’. Such an approach will allow segregation of crew into smaller groups permitting early detection of asymptomatic and pre-symptomatic carriers of virus. The proposed labeling of `Space Cohorts’ expands on the definition of primary contacts for a more effective control of virus transmission. Use of these cohorts as isolation/ quarantine facility offers several operational advantages and can be considered as an option in response to the threat of air-borne pathogens.
Conclusion: It is essential that a warships’ integrity and operational efficiency is maintained. Bases on the proposed model, each ship may need to work out a submodel based on its design, size, crew manning philosophy and operational imperatives. The fresh perspective is recommended for implementation and further validation.
