Trial in Africa Probes Antibiotic’s Effects on Child Mortality
In the mid-2000s, researchers conducted a clinical trial in Ethiopia to see what it would take to eliminate trachoma, a disease caused by the bacterium Chlamydia trachomatis and the most common cause of blindness from infection worldwide. They randomly gave one- to 10-year-old kids either the antibiotic azithromycin to clear and prevent infection or delayed their treatment until after the trial ended.
