Tom McCaffery, assistant secretary of defense for health affairs, speaks during an all-hands call aboard the hospital ship USNS Comfort (T-AH 20) while the ship is anchored off the coast of Port-Au-Prince, Haiti, Nov. 7, 2019. Comfort is working with health and government partners in Central America, South America, and the Caribbean to provide care on the ship and at land-based medical sites, helping to relieve pressure on national medical systems, including those strained by an increase in cross-border migrants.
