South Africa needs to urgently look to countries such as Rwanda, Thailand and Brazil, where they have employed community health workers (CHWs) to deliver a range of primary health care services that dramatically reduced mortality, public health expert Professor David Sanders told the National Health Assembly (NHA). Speaking during a plenary session, Sanders said by extending the scope of what CHWs could do and by supporting properly selected and trained individuals, the country could make a very real impact on maternal and child mortality.
