Airman 1st Class Samantha Downey, 436th Aerospace Medicine Squadron public health technician, puts a germ-simulating lotion on the hands of Alessandra Lowry, a student at the Child Development Center, Oct. 16, 2018, during a hand-washing demonstration at the CDC on Dover Air Force Base, Del. The lotion acts as germs on the children’s hands and even after washing some residue may still show up under a black light. (U.S. Air Force photo by Airman 1st Class Zoe M. Wockenfuss)
