First Lt. Dan Thueneman, executive officer, Intelligence

First Lt. Dan Thueneman, executive officer, Intelligence and Sustainment Company, Headquarters and Headquarters Battalion, 101st Airborne Division (Air Assault), fills out the signs and symptoms checklist before he has his temperature taken, during his 21-day controlled monitoring period at Joint Base Langley – Eustis, Va., Jan. 20, 2015. This check is one of two that happens daily while these troops are in the mandatory 21-day controlled monitoring area. Theuneman is one of the recently returned service members who, for the past three months, has been in Liberia supporting the U.S. Agency for International Development-led mission, Operation United Assistance. Temperature checks allow health care providers to detect EVD early, and are a safeguard taken while deployed to Liberia and stateside during the 21-day controlled monitoring. The 21-day controlled monitoring is a precaution taken to ensure families and communities are confident their service members are healthy. OUA is a Department of Defense operation in Liberia to provide logistics, training and engineering support to U.S. Agency for International Development-led efforts to contain the Ebola virus outbreak in western Africa.
