In this Public Health Yearbook 2016 present you with the epidemiology of arboviruses in Zambia, social work and health inequalities, papers on the risk of HIV/AIDS transmission among adolescents in English speaking Caribbean and many more papers on current public health issues. We bring you paper from the Social Work and Health Inequalities Network (SWHIN) created to combat the causes and consequences of unjust and damaging, socially-produced health inequalities on an international basis. This is accomplished through the sustaining of a global network of social work researchers, educators, practitioners, policy makers, managers, and others working together to promote research, discussion, and action around the world. This global network aims to exchange information and resources (e.g., research evidence, policy statements, systematic reviews of literature, relevant and emerging theories and practice models); collaborate on research and publication; develop and exchange examples of good practice, including good research praxis; develop and exchange ideas on teaching about health inequalities at all curriculum levels; and influence policy making wherever possible. We hope this Yearbook and the research will be of interest to our readers.
