Competing Interests
I have read the journal's policy and the authors of this manuscript have the following competing interests: One of the authors (AD) joined the Pan American Health Organisation (PAHO) during the research period. Work on the research study was undertaken outside and separate to his PAHO duties. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
