For 2-year-old Farida and her family, the trip to Egypt was a pleasant prelude to what would turn into a hard few months. She spent time with relatives in Cairo, visiting her grandparents for the first time. She enjoyed lots of traditional food. She even went to visit her father’s hometown, a rural area several hours south of Cairo.

They began, on and off, without any other symptoms. After two weeks, her mother took her to the family doctor, who prescribed antibiotics for a presumed ear infection. But the fevers didn’t subside.
