Seasonal change in the incidence of infectious diseases is a common phenomenon in both temperate and tropical climates. However, the mechanisms responsible for seasonal disease incidence, and the epidemiological consequences of seasonality, are poorly understood with rare exception. Standard epidemiological theory and concepts such as the basic reproductive number R0 no longer apply, and the im...

Bioethics apparently suffers from a misdistribution of research resources analogous to the '10/90' divide in medical research. Though infectious disease should be recognized as a topic of primary importance for bioethics, the general topic of infectious disease has received relatively little attention from the discipline of bioethics in comparison with things like abortion, euthanasia, genetics...

In the last decade, technological developments have resulted in tremendous increases in the volume and diversity of the data and information that must be processed in the course of biomedical and clinical research and practice. Researchers are at the same time under ever greater pressure to share data and to take steps to ensure that data resources are interoperable. The use of ontologies to an...

Both authors were introduced to infectious disease epidemiology by Alexander D. Langmuir, and he taught us the principles of this field by example. We came to the Communicable Disease Center (now the Centers for Disease Control and Prevention (CDC)) directly out of clinical training with absolutely no formal training in public health or epidemiology. Perhaps this was a fortunate happenstance; i...

EIR April 24, 2009 April 2—The fastest growing infectious disease in the U.S.A. is a spirochetal bacterial infection, similar in symptomology to tertiary syphilis. Untreated it becomes a progressive, degenerative disease that attacks the muscles, joints, central nervous system, heart and other organs, and finally the brain. Infection is characterized by a wide variety of possible symptoms, incl...
