Parallel Treatment
Site 1- Parallel Treatment Arm Single dose azithromycin (for yaws) and Ivermectin/Permethrin (for scabies) will be offered on D1. A second dose of Ivermectin/Permethrin will be offered 7-14 days later. Ivermectin: Participants will be offered treatment for both yaws and scabies either in parallel or in sequence. Ivermectin will be offered as a a single dose 200μg/kg on Day 1 and Day 8. Azithromycin: Participants will be offered treatment for both yaws and scabies either in parallel or in sequence. Azithromycin will be offered as single dose of 30mg/kg, max 2G. Permethrin: Participants will be offered treatment for both yaws and scabies either in parallel or in sequence. Individuals with a contra-indication to ivermectin will be offered Permethrin instead.
Sequential Treatment
Site 2- Serial Treatment Arm Ivermectin/Permethrin (for scabies) will be offered on D1 with a second dose of Ivermectin/Permethrin offered 7-14 days later.. Single dose azithromycin (for yaws) will be offered at the twelve month follow-up visit. Ivermectin: Participants will be offered treatment for both yaws and scabies either in parallel or in sequence. Ivermectin will be offered as a a single dose 200μg/kg on Day 1 and Day 8. Azithromycin: Participants will be offered treatment for both yaws and scabies either in parallel or in sequence. Azithromycin will be offered as single dose of 30mg/kg, max 2G. Permethrin: Participants will be offered treatment for both yaws and scabies either in parallel or in sequence. Individuals with a contra-indication to ivermectin will be offered Permethrin instead.

SECONDARY outcome

Timeframe: 12 Months

Population: Samples were collected at twelve months from individuals with clinical impetigo and cultured for both pyogenic streptococci and S.aureus. This analysis is therefore restricted to the subset of patients who had impetigo from which a swab was collected

Change in the percentage of swab samples from which S. pyogenes is cultured between baseline and 12 month follow-up in the two arms
