Measure
Programmatic Azithro 1-11
Biannual oral azithromycin administration to children aged 1-11 months distributed by community health workers Azithromycin for Oral Suspension: Azithromycin will be administered as a single dose in oral suspension form for children (up to the maximum adult dose of 1g). Dosage will be calculated by age for children aged 1-5 months. For children 6-59 months of age, height-based dosing will be used via height-stick approximation as currently performed by Niger's trachoma program.
