NCT04774991

Brief Summary

This cluster-randomized trial aims to compare the impact of different delivery approaches to azithromycin distribution on coverage, costs, and feasibility outcomes. The investigators hypothesize that door-to-door delivery will have higher coverage and costs and similar feasibility and acceptability compared to fixed-point delivery.

Study Arms (2)

Azithro 1-59 fixed point

ACTIVE COMPARATOR

Azithromycin distribution to children 1-59 months of age using a fixed-point delivery approach via existing community health workers

Drug: Azithromycin for Oral Suspension

Azithro 1-59 door-to-door

ACTIVE COMPARATOR

Azithromycin distribution to children 1-59 months of age using a door-to-door delivery approach via existing community health workers

Drug: Azithromycin for Oral Suspension

Interventions

Azithromycin will be administered as a single dose in oral suspension form for children as follows: * Single-dose of 20mg/kg in children (up to the maximum adult dose of 1g) * For children 1 to \<12 months of age, weight-based dosing will be used * For children 12 to 59 months of age, height-based dosing will be used via height-stick approximation as currently performed by Niger's trachoma program.
