Birrzaf Mesele remembers how it was more than 10 years ago, when she learned she was HIV-positive. Like most people in Mekelle, northern Ethiopia, she had no access to treatment. Then, people who tested positive for HIV would go home and wait to die.
After several misdiagnosis, Ramatoulaye (right) found out that she had tuberculosis (TB). Once recovered, she dedicated herself to educating the population of her neighborhood in Dakar (Senegal) about the symptoms of the disease and the need to adhere to treatment. Today, she does about 20 home visits a day: "I offer these families the kind of support that I had. My sister Bineta (left) supported me through my treatment, making sure that I followed my treatment to the letter and that I ate properly. She also got my children tested regularly."
