This study reviews military vessel diseases to enhance mission success by understanding pathogen spread and prioritizing risks. It proposes a method to classify and rank diseases based on contagiousness and severity to prevent outbreaks.
Area of Science:
- Maritime health
- Infectious disease epidemiology
- Biosecurity
Background:
- Military operations at sea face unique challenges from disease outbreaks.
- Understanding pathogen characteristics is crucial for maintaining crew health and mission readiness.
Purpose of the Study:
- To review and synthesize information on diseases and pathogen characteristics relevant to military vessels.
- To develop a risk prioritization index for onboard infectious diseases.
- To enhance biological resilience and mitigate disease outbreaks during naval missions.
Main Methods:
- Literature review of scientific publications, theses, and public health data.
- Synthesis of bacterial, viral, fungal, and parasitosis characteristics.
- Definition of a risk prioritization index based on basic reproduction number (R0) and clinical severity.
Main Results:
- A risk prioritization index was defined, classifying diseases by contagiousness and severity.
- COVID-19 was assessed as moderately contagious with critical severity.
- Influenza A H1N1 was identified as having minor contagiousness but critical severity, resulting in a level two risk.
Conclusions:
- A systematic approach to classifying and prioritizing diseases on military vessels is feasible.
- Further research is needed on onboard operator activities and pathogen simulation models.
- This framework can improve disease management and operational success in maritime environments.
