WHO Collaborating Centre Trachoma Information Service

The  University of Cape Town’s Division of Ophthalmology was designated as the World Health Organisation Collaborating Centre for Trachoma in 2015. As KCCO is based in this division, we together with a team of experts, invite authors of scientific articles on trachoma to share summaries of their articles that may have programmatic relevance to practitioners in the field.

A repository of the summaries, organized according to the SAFE strategy, is available below. To be added to the distribution list to receive future summaries, please email admin@kcco.net with a request.
