This issue completes Volume 45 and closes out the first year of editorial activity in the Atlanta office of the Journal. The study of health and disease in the tropics is dynamic and increasingly complex. Clinical studies, field epidemiology investigations, application of control technologies, basic biology of disease agents and vectors, immunology, molecular biology, drug studies and what is most exciting, reports of multiple combinations of these subject areas, have all appeared in recent pages of the Journal. This variety is clearly illustrated in the current issue that we like to think of as an end of the year present with something for everyone.
