In the current era of emerging pathogens such as Ebola virus, removal of personal protective equipment (PPE) is crucial to reduce contamination of health care workers. However, current removal practices are not well described. We undertook a systematic evaluation of health care worker removal of PPE for contact isolation to examine variation in removal procedures. Findings indicate that under u...

We describe a population logistic model exposed to a mild lifelong sexually transmitted disease, i.e. without significant increased mortality among infected individuals and providing no immunity/recovery. We then modify this model to include groups isolated from sexual contact and analyze their potential effect on the dynamics of the population. We are interested in how the isolated class may c...

Tephritid fruit flies (Diptera: Tephritidae) include serious agricultural insect pests in the world. Besides causing severe damage to fruits and vegetables, this kind of pests could enter countries or regions with international trade easily. Strict trade quarantine measures are imposed in many countries or regions in order to prevent their introduction and spread. Thus accurate and rapid identi...

The role of facilities and associated services for amphibians has recently undergone diversification. Amphibians traditionally used as research models adjust well to captivity and thrive with established husbandry techniques. However, it is now necessary to maintain hundreds of novel amphibian species in captive breeding, conservation research, and biomedical research programs. These diverse sp...

Strongly held beliefs about the need for contact isolation to prevent the spread of infections in the hospital have contributed to increased costs and decreased flexibility and, more recently, have driven aggressive diagnostic testing for colonization in asymptomatic patients. Examination of the evidence cited in support of the benefits of isolation and growing evidence of its unintended harms ...

Many outbreaks of A(H1N1)pdm09 influenza have occurred in schools with a high population density. Containment of school outbreaks is predicted to help mitigate pandemic influenza. Understanding disease transmission characteristics within the school setting is critical to implementing effective control measures. Based on a school outbreak survey, we found almost all (93.7%) disease transmission ...

We address the changes in Brazilian maritime prophylaxis by studying two cases of immigrant ships arriving at the port of Rio de Janeiro with epidemics onboard. The objective is to understand the etiology, means of prevention and methods used to combat the three diseases subject to international port regulations: yellow fever, bubonic plague and cholera. Until the late nineteenth century, quara...

To the Editor: Since 1975, federal quarantine regulations (1) have restricted nonhuman primate importation to scientific, educational, or exhibition purposes to limit risks for disease introduction (1,2). Infectious diseases resulting from importation of nonhuman primates need to be prevented to ensure that colonies of these animals are available for research and to protect persons working with...
