US Military Deployments

In 2016, approximately 1.3 million US military members were on active duty, and approximately 800,000 were in the reserve forces. The US military, as a matter of policy, follows most of the recommendations in the CDC Yellow Book. However, certain situations apply only to the US military, and some policies or recommendations differ from what is recommended in the Yellow Book for civilian travel. Active-duty military physicians generally manage predeployment medicine, but civilian physicians may interact with people who are on reserve status, home on leave, recently discharged from active duty, or veterans. Providers can find predeployment and postdeployment information, policies, and guidelines for clinicians, service members and their families, and veterans on the Deployment Health Clinical Center website (www.pdhealth.mil).
