Polio eradication -- Index. 330 3 $aAs per the World Health Organization (WHO), public health refers to all organized measures (whether public or private) to prevent diseases, promote health, and prolong life among the population as a whole. Unfortunately, public health continues to remain neglected in many developing countries due to poor management capacity for effective and efficient delivery of public health services. This book starts with an overall view of public health issues at the global, national and sub-national levels. Challenges faced in the management of global public health programs are illustrated through mini-case studies on Adolescent health, HIV/AIDS, Diarrhoea control, and TB control programs. Live case studies from India towards achieving Millennium Development Goals (MDGs) on maternal health, child health, urban health, and polio eradication highlight the managerial challenges on planning and implementing global public health policies in developing countries. Evidence-based strategic planning, micro-level operational planning, closely monitored implementation, and a well-designed surveillance system are critical for the success of global public health policies in developing countries. 410 0$aEconomics collection.$x2163-7628 606 $aMedical policy$zIndia$vCase studies 606 $aHealth Planning$zIndia 606 $aPublic Health$zIndia 610 $aPublic health policies 610 $aStrategic Planning 610 $aOperational Planning 610 $aImplementation 610 $aSurveillance 610 $aMDGs 615 0$aMedical policy 615 2$aHealth Planning 615 2$aPublic Health 676 $a362.10954 700 $aRamani$b K.
