Incidences of Staphylococcus aureus and methicillin resistant S. aureus (MRSA) have risen worldwide prompting a need to better understand routes of human exposure and whether standard bacterial water quality monitoring practices adequately account for this potential threat. Beach water and sand samples were analyzed during summer months for S. aureus, enterococci, and MRSA at three southern Cal...
To the Editor—Severe acute respiratory syndrome (SARS) emerged last year as a new infectious disease, as well as an occupational hazard for health care workers treating infected patients. The Centers for Disease Control and Prevention (CDC) recently drafted guidlines suggesting that routes of transmission of the SARS-associated coronavirus (CoV) involve the mucous membranes, such as the respira...
Characterizing infectivity as a function of pathogen dose is integral to microbial risk assessment. Dose-response experiments usually administer doses to subjects at one time. Phenomenological models of the resulting data, such as the exponential and the Beta-Poisson models, ignore dose timing and assume independent risks from each pathogen. Real world exposure to pathogens, however, is a seque...
Available evidence demonstrates that direct patient contact and contact with infectious body fluids are the primary modes for Ebola virus transmission, but this is based on a limited number of studies. Key areas requiring further study include (i) the role of aerosol transmission (either via large droplets or small particles in the vicinity of source patients), (ii) the role of environmental co...
Fomites are inanimate objects that are capable of absorbing, harboring and transmitting infectious microorganisms. Paper currency, an exchangeable fomite, is constantly subjected to contamination. This study investigated bacterial contamination on the Saudi one Riyal paper note. Two hundred one Riyal bills (100 4th version and 100 5th version) were collected in the city of Jeddah for examinatio...
Contaminated touch surfaces have been implicated in the spread of hospital-acquired infections, and the use of biocidal surfaces could help to reduce this cross-contamination. In a previous study we reported the death of aqueous inocula of pathogenic Enterococcus faecalis or Enterococcus faecium isolates, simulating fomite surface contamination, in 1 h on copper alloys, compared to survival for...
Public health teams need to understand how the public responds vaccination messages in a pandemic or epidemic inform successful campaigns encouraging uptake of new vaccines as they become available. A rapid systematic review was performed by searching PsycINFO, MEDLINE, healthevidence.org, OSF Preprints and PsyArXiv May 2020 for studies including at least one message promoting vaccine airborne-...
The reuse of filtering facepiece respirators (FFRs) after decontamination has been suggested as a strategy to conserve supplies during an influenza pandemic. The feasibility of decontaminating FFRs has been investigated under laboratory conditions; however, the need for decontamination of FFRs is not well characterized. In this study the potential for FFRs to act as fomites was examined using b...
Zoonotic infections by avian influenza viruses occur at the human-poultry interface, but the modes of transmission have not been fully investigated. We assessed the potential for airborne and fomite transmission at live poultry markets in Guangzhou city and in Hong Kong Special Administrative Region (SAR), China, during 2014 and 2015. Viral genome and infectious avian influenza A viruses of H5N...
