The authors' purpose was to expand sexually transmitted disease core theory by examining the roles of person, place, and time in differentiating geographic core areas from outbreak areas. The authors mapped yearly census-tract-level syphilis rates for San Francisco, California, based on new primary and secondary syphilis cases reported to the San Francisco City sexually transmitted disease surv...
objectives the aim of this was to indentify the presence of a/h9n2 virus among different high risk occupational groups, in tehran and qazvin provinces in seasonal outbreak in iran. background in the last decade h9n2 avian influenza viruses had caused outbreaks in poultry in many parts of the world. this subtype could infect other animals such as human and pig. avian h9n2 virus has acquired rece...
Salmonellosis and Meat Purchased at Live-Bird and Animal-Slaughter Markets, United States, 2007–2012
To the Editor: Salmonella spp. cause ≈1.2 million human illnesses annually in the United States (1). Infections are primarily acquired through exposure to contaminated food or infected animals (1,2). Since 2007, state and local health departments and the Centers for Disease Control and Prevention have investigated multiple salmonellosis outbreaks linked to meat purchased at live-bird markets (L...
We built a SEIR (susceptible, exposed, infected, recovered) model of smallpox transmission for New York, New York, USA, and Sydney, New South Wales, Australia, that accounted for age-specific population immunosuppression and residual vaccine immunity and conducted sensitivity analyses to estimate the effect these parameters might have on smallpox reemergence. At least 19% of New York's and 17% ...

METHODS We conducted case finding, a case-control study, and traceback and microbiological investigations to determine the extent and so...
The ability to effectively modify behaviours is increasingly relevant to attain and maintain a good health status. Current behaviour-change models and theories present two main approaches for (healthier) decision-making: one analytical/logical, and one experiential/emotional/intuitive. Therefore, to achieve an integral and dynamic understanding of the public perceptions both approaches should b...
BACKGROUND Early warning systems for outbreaks of infectious diseases are an important application of the ecological theory of epidemics. A key variable predicted by early warning systems is the final outbreak size. However, for directly transmitted diseases, the stochastic contact process by which outbreaks develop entails fundamental limits to the precision with which the final size can be pr...
To the Editor: Previously, we reported the use of whole-genome sequencing to investigate a putative methicillin-resistant Staphylococcus aureus (MRSA) outbreak in 2011 in the special care baby unit (SCBU) at the Cambridge University Hospitals National Health Service Foundation Trust (CUH) in the United Kingdom (1). The report identified 26 related cases of infection with or asymptomatic carriag...
Letters clinical presentation of the patients, response to trivalent botulinum antitoxin, and isolation of toxigenic C. butyricum from one of the consumed food articles strongly suggest that the outbreak was caused by food contaminated with toxigenic C. butyricum. Neurotoxigenic C. butyricum was first reported in 1986 in two cases of infant botulism in Rome (6). Recently, neurotoxigenic C. buty...
