Foreword
This textbook is long overdue. A set of unfortunate circumstances, partly biological, partly historical, indelibly political, resulted in the province of Kwazulu-Natal (KZN) being the region which bore the heaviest burden of the HIV epidemic in South Africa. KZN is also the region in the country with few health resources to cope with the sheer floods of people infected with HIV. The indicators of poverty and human suffering are at their most pernicious in this province; man and nature, it seems, conspired to prepare the most receptive sites, for the spread of the HIV epidemic, here around eThekwini. So it is a particular pleasure and a sense of fulfilment for me to see one of my colleagues, Professor Raziya Bobat, leading this team of outstanding co-authors, all thoroughly tested through the exigencies of the darkest years of the AIDS epidemic here in our midst, to put together a highly informative textbook on children and HIV. Professor Bobat has been at the heart of the epidemic of HIV as it first appeared in Durban, in the late 1980s, and with little to impede its advance through our societies; she watched with frustration the spread and growth of this epidemic. The state was embroiled in its own mysterious cogitations on the source, treatment and outcome of one of the most dreadful epidemics to hit our shores. Antiretroviral drugs appeared much later having become a proven and effective means of prevention and treatment. Indeed, her presence at the largest public hospital in the province enabled her to utilize whatever patients, public and academic resources were available to record the initial appearance and the rapid spread of this treacherous virus. This textbook is the victory of science, and society over the frustration and even despair of this very debilitating experience. It is fitting to pay the highest respect and recognition to our little patients who bore their pain and suffering with fortitude. Raziya Bobat has succeeded in calling on some of the most resourceful and knowledgeable individuals in this region to share their discoveries of care and treatment, with the next generations and those who choose unselfish healthcare as their preferred contribution to relieve the suffering of children and their mothers and families. This new book on paediatric HIV infection will serve as a useful textbook on paediatric HIV infection, with a wide range of data and information on the subject. The list given below, of the 23 chapters covering the depth and width of paediatric HIV, conveys a fair idea of the material from epidemiology, pathogenesis and transmission to clinical manifestations, treatment and prevention. In addition, areas such as HIV and TB co-infection, opportunistic infections, v

Foreword
immunization in HIV, HIV and the microbiome and special populations (neonates and adolescents) are covered. Individual chapters are contributed by expert authors. Numerous case reports are included providing the reader with a useful guide through all relevant topics in the field. In reviewing this book as objectively as is possible under the circumstances of my personal acquaintance with many of the authors, each chapter has a credible story to tell. I gave each chapter a rough estimate, a numerical score of fitness for purpose. I took this purpose to be the assimilation of knowledge, learning and education on one of the worst epidemics to cross the borders of South Africa; the type of data available in this book will be of immense value to those seeking more scientific information on HIV in the region: primary care health personnel, clinicians, nurses, laboratory technicians, policymakers, etc. indeed virtually anyone wanting to make sense of the origins and ravages of HIV in southern Africa, within the shadows of the whole continent and globally. My attempts at scoring the chapters were met by a solid wall of sameness! In the event, the scores were all within a very narrow range, implying a consistency which was gratifying. Even before I conducted this little assessment, I knew the standards were quite high. It is obvious to me that Raziya Bobat has chosen very carefully and that there is a wealth of talent in the country on HIV. The individuals who require a deeper level of knowledge will also not be disappointed; there are many references to guide the ardent seeker of HIV data. Prof H. M.

Abstract
Research into HIV/AIDS has set a new precedence in the global health arena. The gains achieved in determining the epidemiology and burden of disease, in both resource rich and limited countries cannot be overestimated. The epidemic had merged medical and public health fraternities into collaborations to expedite the implementation of HIV prevention programmes internationally. With a heartening decline in mother to child transmissions of HIV, emphasis may now be directed to improving the quality of lives in children and adolescents living with HIV. Keywords

In a world divided by economic inequalities, political strife and religious beliefs, human immunodeficiency virus (HIV) resulting in acquired immune deficiency syndrome (AIDS), has unified a global commitment to eliminate its transmission and improve the quality of lives of children and adolescents living with HIV (CALHIV). Eventual elimination in the foreseeable, albeit distant future, would be the ultimate achievement in public health.

History
Paediatric AIDS was first described in the early 1980s. A few cases of unexplained cellular immunodeficiency and opportunistic infections were reported in infants, in the United States of America (USA) [1]. Since then, it has culminated in Sub Saharan Africa (SSA) firmly establishing itself as the epicentre of the current HIV epidemic.

Epidemiology and Burden of Disease
• There are an estimated 36 million people living with HIV/AIDS (PLHA) globally. • Approximately 1.8 million are children less than 15 years old. • In 2017 there were 7.2 million PLHA reportedly living in South Africa (SA). • Of these, 280,000 were children (0–14 years) living with HIV, only 58% of whom were accessing ART. • Of the 270,000 new HIV infections recorded in 2017 in SA, 13000 were children [2]. For a number of years, elimination of mother to child transmission (EMTCT) remained the cornerstone of clinical and public health research. Evidence from multi-centre, landmark studies in both resource limited and resource rich settings, has resulted in numerous national and international interventions being implemented to attempt to halt the spread of HIV. In May 2016, SA became one of the first African countries to implement the Universal Test and Treat (UTT) policy, in accordance with WHO guidelines on HIV treatment. The UNAIDS 90–90–90 strategy aims were to diagnose 90% of all HIV infected persons, provide ART for 90% of those diagnosed, and achieve virologic suppression in 90% of those treated, by 2020 [3]. To date a majority of the persons infected with HIV in SA are aware of their status. The percentage of infected persons accessing ART is lower and the percentage that have virologic suppression is even lower [2]. This highlights the deficiencies in HIV continuum of care (CoC) in our setting. Unless programmes and policies are more urgently instituted, attrition will continue in every step of the care cascade. South Africa’s National Strategic Plan (NSP) for HIV, tuberculosis and sexually transmitted infections (STI) for 2017–2022, was launched in 2017. The aims set out by the NSP were to eliminate HIV, TB and STIs as public health problems in 5 years [4]. The focus is on specific areas and populations within SA where the incidence and burden of disease was greatest. The aim is to implement sustainable interventions with measurable outcomes and strengthen the systems and processes to achieve these goals. The NSP identified groups of individuals who are at particularly high risk of acquiring HIV. This included women, adolescent girls, children and orphans [4].

In 2016 the ‘Start Free, Stay Free’ initiative by UNAIDS and PEPFAR, attempted to more urgently address HIV prevention, treatment, care and support services to children, adolescents and young women. The prevalence of HIV in young women in SA is higher than that of men, of the same age group [5]. Young women and adolescent girls, in particular, contribute to the significant number of new HIV infections. There has been a noticeable decline in the number of new infections in children (0–14 years). More young people (15–24 years) and adolescents (10– 19 years) are becoming infected with HIV and dying from AIDS related deaths [5]. AIDS is now the leading cause of death in young people in Africa [2]. In 2017 more than 95% of pregnant women living with HIV in SA were accessing ART and more than 95% of babies born to mothers who were HIV positive had an early infant diagnosis (EID) [6]. With SA’s national in utero (IU) transmission rates estimated at
