Control of health care-associated infections (HAI): winning both the battles and the war.

At present, the United States (US) experiences its greatest life expectancy due mainly to improvements in mortality from cardiovascular diseases, which include coronary heart disease and stroke. These, in turn, are due largely to decreases in cigarette smoking as well as earlier and more aggressive diagnoses and treatments. These advances in health care delivery are, not surprisingly, accompanied by increasing numbers of complicating health care-associated infections (HAI). HAIs are a major and increasing cause of morbidity and mortality in the US as well as around the world. To win both the battles and the war against HAI requires a multidisciplinary approach to the vigorous implementation and maintenance of proper infection control procedures. This should include continuous surveillance and reinforcement of guidelines to enhance evidence-based practices to prevent and control HAI. It will also be necessary to implement a new paradigm of early and formal education of future health care providers into the biology of infection as well as the principles of infection control in the classroom and subsequently, with translation into their clinical training. Finally, there must also be the incorporation and expansion of continuing medical education for established health care providers about prevention and control of HAI.

Origin of the old testament plagues: explications and implications.

Analyses of past disasters may supply insights to mitigate the impact of recurrences. In this context, we offer a unifying causative theory of Old Testament plagues, which has present day public health implications. We propose the root cause to have been an aberrant El Niño-Southern Oscillation teleconnection that brought unseasonable and progressive climate warming along the ancient Mediterranean littoral, including the coast of biblical Egypt, which, in turn, initiated the serial catastrophes of biblical sequence - in particular arthropod-borne and arthropod-caused diseases. Located beyond the boundary of focal climate change, inland Goshen would not have been similarly affected. Implicit in this analysis is a framework to consider a possibility of present day recurrence of similar catastrophes and their impact upon essential public services.
