War/Disaster-Associated Bacterial Pathogens
Vibrio cholerae and Salmonella typhi. 1
- Rationale:
- The most recent, high-quality synthesis specific to wars and disasters in Asia/Middle East (Expert Review of Anti-infective Therapy, 2020) highlights water- and sanitation-borne outbreaks—particularly cholera and typhoid—as recurrent causes of morbidity, mortality, and QOL decline among displaced populations and crowded shelters during conflicts and natural disasters. 1
- Options featuring biowarfare agents (Bacillus anthracis, Clostridium botulinum) are not typical “common” pathogens in natural war/disaster infections; tuberculosis/pneumococcus reflect baseline respiratory pathogens rather than disaster-specific spikes; Enterobacterales (E. coli/K. pneumoniae) are frequent in nosocomial/trauma settings but the question targets “infections during wars and disasters” broadly, where fecal–oral epidemics dominate population-level outcomes. 1
Algorithmic reasoning focused on morbidity, mortality, QOL:
- Population-level outbreaks in displacement/overcrowding with unsafe water:
- Prioritize fecal–oral pathogens causing explosive epidemics and high CFR without rapid WASH and vaccination: cholera (V. cholerae) and typhoid (S. typhi). 1
- Facility/trauma-care MDR issues (Acinetobacter/Klebsiella) matter for surgical morbidity but are less representative of “common” war/disaster-wide infections across civilians. Guidelines provided focus on AMR drivers but do not contradict outbreak primacy of cholera/typhoid. 2
Common pitfalls:
- Confusing bioterror agents with common disaster pathogens.
- Overweighting hospital MDR organisms when the question targets broad war/disaster infectious patterns.
