Competing Interests

I have read the journal’s policy and the authors of this manuscript have the following competing interests: Upendo Mwingira is non-financially affiliated with RTI International, an independent non-profit research institute involved with the implementation of some of the trachoma control programmes in Tanzania. She is also non-financially affiliated with the National Institute for Medical Research Tanzania. The remaining three authors (Kaki Tsang, Gilles de Wildt and Tara Mtuy) have no competing interests.
