  • Household air pollution exposure and respiratory health outcomes : a narrative review update of the South African epidemiological evidence 
    Shezi, Busisiwe; Wright, Caradee Yael (National Association for Clean Air, 2018)
    One of the greatest threats to public health is personal exposure to air pollution from indoor sources. The impact of air pollution on mortality and morbidity globally and in South Africa is large and places a burden on ...
  • Household fuel use and child respiratory ill health in two towns in Mpumalanga, South Africa 
    Albers, Patricia Nicole; Wright, Caradee Yael; Voyi, K.V.V. (Kuku); Mathee, Angela (Health and Medical Publishing Group, 2015-07)
