AcknowledgmentsWe sincerely thank the office of USAID REDSO/ESA, based in Nairobi, Kenya, for agreeing to fundthe entire production of this handbook, including the many meetings the authors and editorsheld to put the chapters together. We are grateful to Family Health International for managing thecopyediting, design, and printing.USAID/REDSO funded this activity through the Regional Centre for Quality of Health Care(RCQHC) at Makerere University, to which we are also grateful.We also thank USAID/REDSO for funding the African Network for the Care of Children Affected byAIDS (ANECCA) in its broader efforts to improve the care of HIV-affected and -infected childrenin Africa.ANECCA is an informal network of health workers and social scientists committed to finding waysto improve care for HIV-exposed and -infected children in Africa. Members of the network identified the fact that while there are widespread knowledge gaps in the care of HIV-infected childrenin Africa, there are nonetheless scattered experiences across the continent that need to be shared.They thus volunteered their time to put together this book. It was a long and sometimes stressfulprocess. Because some issues concerning paediatric AIDS had no clear-cut international or nationalguidelines, network members had to reach consensus, sometimes through intense discussions. Ithank them for the mature and professional manner in which they held these discussions to reachthe consensus reflected in this handbook.As much as possible, and where they do exist, we have tried to remain within the available international guidelines from WHO or UNICEF, and these are acknowledged.ANECCA members who are authors of this handbook also form the core of their respectivenational committees on paediatric AIDS care, and some sections resemble what appears in theirnational guidelines. We therefore acknowledge these national guidelines and the individual authorswho provided us with the materials therein. Special mention goes to our colleagues in South Africa(Prof. H. Coovadia, Prof. Raziya Bobart, Dr. Brian Eley, and Dr. Tammy Meyers).We would also like to acknowledge comments received after the launch of the preliminary editionat the International AIDS Conference in Bangkok in July 2004. Special thanks go to Dr. Peter Salamaof the USAID Africa Bureau in Washington and Dr. Timothy Quick of the USAID Global HealthBureau, also in Washington.We would like to thank all of the enthusiastic readers who have sent in numerous requests for copies of the initial handbook and who, in the process, have expedited this final edition.Dr Denis TindyebwaChairpersonAfrican Network for the Care of Children Affected by AIDS (ANECCA)ANECCA SecretariatRegional Centre for Quality of Health CareP O Box 29140Kampala, UgandaTel 256-41-530888Fax 256-41-530876Email dtindyebwa@rcqhc.org or anecca@rcqhc.orgThe handbook will be available at the Regional Centre for Quality of Health Care Web site:www.rcqhc.org

IntroductionHIV/AIDS is a major cause of infant and childhood mortality andmorbidity in Africa. In children under five years of age, HIV/AIDSnow accounts for 7.7% of mortality worldwide. AIDS already accountsfor a rise of more than 19% in infant mortality and a 36% rise in underfive mortality. Together with factors such as declining immunisation,HIV/AIDS is threatening recent gains in infant and child survival andhealth.Yet, for the most part, HIV infection in children is preventable. Inindustrialised countries in North America and Europe, paediatric HIVinfection has largely been controlled. In these settings, HIV testing aspart of routine antenatal care, combinations of antiretroviral (ARV)drug regimens, elective caesarean section, and complete avoidanceof breast-feeding have translated into mother-to-child transmission(MTCT) rates of less than 2%.In Africa, on the other hand, high rates of maternal HIV infection,high birth rates, lack of access to currently available and feasible interventions, and the widespread practice of prolonged breast-feedingtranslate into a high burden of paediatric HIV disease. The transmission risk for a child born to an HIV-infected mother in an Africansetting without interventions for prevention of mother-to-child transmission (PMTCT) is about 30–40%. The other 60–70% of children,although not HIV-infected, still have a 2- to 5-fold risk of mortality asa direct consequence of the mother’s HIV disease, when compared tochildren born to uninfected mothers.Efforts to expand care and treatment for children must go hand inhand with efforts to rapidly improve the uptake of available interventions for reducing MTCT. Currently these reach less than 10% of thepopulation in the countries that are most affected. Access to currentlyavailable, effective care and treatment remains
