In this Tuesday, Nov. 5, 2019, photo, a migrant child's tears are wiped away by her mother as they receive medical care at a sidewalk clinic in refugee camp in Matamoros, Mexico. The few doctors and nurses working in the camp are treating people including pregnant women and children with respiratory problems, skin conditions, diarrhea, and other diseases that can be linked to the camp’s unsanitary conditions.
