It appears that the risk of dyspepsia, constipation, and GERD are higher among those who have AGE during a confirmed norovirus outbreak. Although these findings need confirmation, they suggest that dysmotility may result subsequent to these infections. If confirmed, the costs and morbidity associated with the chronic consequences of norovirus should be considered.

Much has been written about injury, diarrhea, and respiratory cases but less is known about other threats, specifically snake, scorpion, and spider encounters. To examine the risk from local fauna, a cross-sectional study using an anonymous survey was conducted among U.S. troops in Southwest Asia between January 2005 and May 2006. Among 3,265 troops, 9 cases (0.3%) of snakebites and 85 cases (2.6%) of spider stings and scorpion bites were reported, equating to an incidence of 46.1 per 10,000 person-months for scorpion/spider encounters and 4.9 per 10,000 person-months for snakebites. There was a significant association with service branch and toileting facilities for snakebites. Season, deployment location, rank, and toileting facilities were associated with differential risk of scorpion/spider encounters. Troops are at risk for local fauna encounters while deployed in the current operational environment. The potential morbidity, mortality, and operational impact of these health hazards need to be considered.

Noncombat injuries and illnesses have had a significant impact on military missions and continue to result in force health protection challenges today. Future studies are needed to test and evaluate countermeasures to mitigate these illnesses and injuries to increase the health of the individuals and optimize mission readiness.

Results from this survey support the need for improving knowledge and management of TD among deploying providers. The information from this study should be considered to support the establishment and dissemination of military diarrhea-management guidelines to assist in improving the health of military personnel.
