Fever, headache, and myalgias after deployment to the Philippines.

Classic dengue fever presents with a triad of fever, headache, and rash. A "saddleback" fever pattern, morbilliform rash with islets of sparing after apyrexia, and hematological/hepatic abnormalities are common findings. As the most common arbovirus infection, dengue is a significant health threat to deployed military forces worldwide. preventive measures such as personal protective equipment and repellants should be employed by individuals and other preventive measures should be considered for units departing endemic areas. Due to the increased risk of severe or hemorrhagic syndromes in the case of reinfection, limiting redeployment of individuals who have been infected by dengue should be considered, and further research is needed in this area. Development of tetravalent or DNA-based vaccines should be a priority to improve health protection for deploying forces.
