This book discusses key strategic options for private sector engagement in order to scale up malaria prevention and treatment. It aims to provide action-oriented and evidence-based guidance, applicable and/or adaptable to various countries and contexts, for options to involve the private sector and using public-private partnerships (PPPs) in the expansion of malaria control interventions. It is based on current recognized best practice in treatment and prevention of malaria, and draws lessons mainly from experience in Sub-Saharan Africa and Asia. The book also advocates implementation research and illustrates how different options lead into country specific implementation research studies. It is therefore a 'hands-on' publication for policy makers and advisers, organisations financing or implementing malaria intervention programmes, programme managers and staff of Ministries of Health.
