Malaria - one of the infectious diseases of major public health concern Globally (WHO, 2005) Eradicated in some countries - But still a major health issue: • tropical and subtropical countries (WHO, 2005 & CDC, 2010). • Sub-Saharan African Countries – mainly affected (CDC-2010) References World Health Organization, WHO, (2005).

Ghana Community-Based Health Planning and Services(CHPS) Program: An Innovative way for scaling up service delivery 2. Why great success with program in Ghana: • Bridges gap between main-stream health programs and the community Nyonator, F.K., Awoonor-Williams, J.K., Phillips, J.F., Jones, T.C. and Miller, R.A.

Why great success with program in Ghana: • Bridges gap between main-stream health programs and the community • CHPS program – works with community leaders before implementation • Community health Officers (CHO) – for the program are familiar members of the community Nyonator, F.K., Awoonor-Williams, J.K., Phillips, J.F., Jones, T.C. and Miller, R.A.
