Nadine Mendes, 28, recovers at a Médecins sans Frontières cholera treatment center in Bissau, Guinea-Bissau, Nov. 14, 2012. Mendes is five months pregnant with her first child, and will remain connected to intravenous fluids until she is well enough to go home. A cholera epidemic started in April in West Africa's densely-populated, low-lying coastal areas, killing hundreds of people in Sierra Leone and Guinea. By mid-November, more than 2,100 cholera cases had been reported in Guinea-Bissau.
