Ethics approval and consent to participate
: The purpose of the study was explained in the preferred language of the primary caregiver. Participating caregivers provided written consent on behalf of all household members to provide household-level data. For each household member aged ≥18 years on whom individual data were collected, verbal consent was obtained from the individual. If that person was unavailable, the primary caregiver verbally consented and answered on behalf of the unavailable individual. For persons aged < 18 years, the primary caregiver provided information on behalf of that individual. The study was determined to be within the scope of public health practice by the U.S. Centers for Disease Control and Prevention (ID #2012 6165). The study protocol was also reviewed and approved by the University of Witwatersrand Human Research Ethics Committee (Medical) (Approval #M120367) and received local authority approval from North West Province and Matlosana Sub-District.
