In this article, we develop a layered networked spread model for susceptible-infected-susceptible pathogen-borne disease spreading over human contact network and an infrastructure network, refer to it as susceptible-infected-water-susceptible (SIWS). The “W” in SIWS represents any contamination, not necessarily restricted water distribution network. We identify sufficient conditions the existen...

The purpose of this descriptive study was to assess home health care nurses' exposure to bloodborne pathogens, evaluate Medicare Certified Home Healthcare Agency (MCHHA) and hospice organization practices related to the Occupational Safety and Health Administration's (OSHA) Bloodborne Pathogens Standard and the Needlestick Safety and Prevention Act, and link the two to recommend safety improvem...

A retrospective cohort study was conducted examining health care worker (HCW) compliance with Centers for Disease Control and Prevention recommendations following occupational bloodborne pathogen (BBP) exposure. HCWs with a BBP exposure from a known HIV- or hepatitis C virus-seropositive individual were less likely to complete recommended follow-up compared with HCWs with seronegative source pa...

   ABSTRACT  Human blood and blood products is the source of a wide range of medicinal products used for the treatment and prevention of a variety of injuries and disease. Despite stringent routine measures and filters employed, residual pathogen infectivity remains an important challenge in the field of blood transfusion. In this article various measures and technologies that can be applied in...

in vitro studies with trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. microscopic observations showed that t. harzianm and t. viride, isolated from soil samples from ahwaz and karaj, adversely affected the mycelial ...

Tick-borne encephalitis virus is an important human pathogen in Europe. The infection usually presents as meningitis, meningoencephalitis, or meningoencephalomyelitis and only rarely as symptoms of isolated myeloradiculitis. We describe the lumbar MR imaging finding in a 48-year-old man with serologically confirmed tick-borne encephalitis in which there was enhancement of the ventral surface of...

The Ross-Macdonald model has dominated theory for mosquito-borne pathogen transmission dynamics and control for over a century. The model, like many other basic population models, makes the mathematically convenient assumption that populations are well mixed; i.e., that each mosquito is equally likely to bite any vertebrate host. This assumption raises questions about the validity and utility o...

The spread of pathogens into new environments poses a considerable threat to human, animal, and plant health, and by extension, human and animal wellbeing, ecosystem function, and agricultural productivity, worldwide. Early detection through effective surveillance is a key strategy to reduce the risk of their establishment. Whilst it is well established that statistical and economic considerati...
