Wastewater Surveillance for Disease Monitoring on Military Vessels
Overview
Wastewater surveillance has demonstrated potential as an effective tool for monitoring infectious disease outbreaks on military vessels, as evidenced by studies on U.S. Air Force bases, Coast Guard cutters, and the French aircraft carrier Charles-de-Gaulle. Implementing such surveillance can enable early detection and mitigation of outbreaks among deployed armed forces personnel.
Background
The COVID-19 outbreak aboard the U.S.S. Theodore Roosevelt highlighted the vulnerability of military vessels to infectious diseases and the need for improved surveillance methods. Traditional clinical testing on ships is limited by logistical challenges and preparedness of medical personnel. Wastewater surveillance offers a non-invasive, cost-effective approach to monitor viral presence in confined populations, with successful precedents in military and civilian settings. Recent Department of Defense guidance recommends leveraging wastewater surveillance to supplement existing COVID-19 monitoring systems.

Key Findings
Over 1,300 crew members were infected during the COVID-19 outbreak on the U.S.S. Theodore Roosevelt, underscoring the risk of onboard disease spread.
Wastewater surveillance programs on military bases have proven feasible and cost-effective compared to clinical testing.
Advanced metagenomic techniques can detect a wide range of viral families in wastewater samples, enhancing surveillance capabilities.
Wastewater testing on seaborne vessels is viable but requires tailored sampling and analysis protocols due to operational constraints.
Military guidance now recommends integrating wastewater surveillance to supplement existing infectious disease monitoring systems.
Implementation raises unique ethical considerations and necessitates methods accessible to personnel without advanced microbiological training.
Clinical Implications
Incorporating wastewater surveillance on military vessels can provide early warning of infectious disease outbreaks, allowing timely interventions to protect crew health and maintain operational readiness. Cost savings and non-invasive sampling make this approach practical for confined military populations. Training and ethical frameworks should be developed to support effective and responsible implementation.
Conclusion
Wastewater surveillance represents a promising strategy to enhance disease outbreak monitoring on military vessels, improving preparedness and response for deployed armed forces. Continued research and tailored program development are needed to optimize its application in maritime military settings.
