Background The strikingly young age of new variant Creutzfeldt-Jacob disease (vCJD) cases remains unexplained. Age dependent susceptibility to infection has been put forward, but differential dietary exposure to contaminated food products in the UK population according to age and sex during the bovine spongiform encephalopathy (BSE) epidemic may provide a simpler explanation. Methods Using rece...
Bedbugs are brown and flat hematophagous insects. The 2 cosmopolite species, Cimex lectularius and Cimex hemipterus, feed on humans and/or domestic animals, and recent outbreaks have been reported in occidental countries. Site assessment for bedbug eradication is complex but can be assured, despite emerging insecticide resistance, by hiring a pest-control manager. The common dermatological pres...
Disease ecology takes into consideration a broad spectrum of factors comprising the tapestry of a human being's day-today life experience. A disease ecology perspective is one that places human health within the context of a human being's interactions within a wide array of environments. These include the physical environment that surrounds us as well as the social and cultural environments all...
Twenty-five years ago, the development of molecular biology and recombinant DNA technology promised breakthroughs in infectious disease research. Since then, these methods have slowly teased out molecular secrets of microbial infection, gene by gene. Now, with the advent of whole-genome sequencing, a new revolution in infectious disease research has begun. Genomics is a top-down approach to the...

Transmission of Lassa virus (family Arenaviridae) from its natural rodent reservoir to humans can cause hemorrhagic fever, a clinical syndrome associated with high death rates. Lassa fever is endemic in West Africa and has been reported from Sierra Leone, Guinea, Liberia, and Nigeria (1-4). The geographically restricted occurrence of the disease is not well understood as its rodent host (Mastom...
On the cover: Calavera of the Morbid Cholera, etching on paper, 1910, by José Guadalupe Posada (Mexican,1852–1913). Library of Congress Prints and Photographs Division Washington, D.C. USA. Public Domain. Calaveras (Spanish for skulls), have been produced in Mexico as a form of satirical art for over a hundred years, having been popularized in this use by celebrated Mexican printmakers Manuel M...
The spectrum of human pathogens and the infectious diseases they cause is continuously changing through evolution and changes in the way human populations interact with their environment and each other. New human pathogens most often emerge from an animal reservoir, emphasizing the central role that non-human reservoirs play in human infectious diseases. Pathogens may also re-emerge with new ch...
This article reviews the available literature on medical elementology in relation to epidemiology and also discusses its research potentialities for development.
The humoral and cellular response of the host against a virus is a natural selective constraint operating during virus replication in vivo. While acutely infecting viruses have the chance of escaping the host in a very short time, viruses persistently infecting the host are forced to cope with the adaptive host immune response, that the virus itself must modulate, disrupt, or evade with genetic...
