Nonpharmaceutical Interventions for Military Populations During Pandemic Influenza

Influenza causes substantial illness and loss of work days among young adults, and outbreaks can affect the preparedness of military units. In an influenza pandemic, people who live in confined settings have greater risk of infection. Military trainees are at particularly high risk. Because of likely unavailability of vaccines and antiviral drugs at the start of a pandemic and for many months thereafter, nonpharmaceutical interventions may be very important. During a pandemic, it seems prudent that military public health officials employ at least several nonpharmaceutical interventions. For example frequent handwashing and respiratory hygiene/cough etiquette should be strongly encouraged among soldiers. Head-to-toe sleeping, a "no-cost" intervention should be for crowded berthing areas. Isolation of patients with influenza and quarantine of their close contacts should be employed. Masks and alcohol-based hand rubs may be employed among those at highest risk. Finally, whenever possible military planners should, reduce crowding and limit the interaction of training cohorts to reduce risk of influenza virus transmission.
