Simulations using fluorescent tracers can be useful in understanding the spread of pathogens and in devising effective infection control strategies. In a study reported by Alhmidi, et al. (2016), during simulated patient care interactions in which providers wore gloves and gowns, researchers evaluated environmental and personnel dissemination of fluorescent lotion and bacteriophage MS2 from a contaminated mannequin. The frequency of skin and clothing contamination after removal of personal protective equipment (PPE) was compared before versus after an intervention that included education and practice in PPE donning and doffing.
Ten healthcare personnel participated in 30 pre-intervention and 30 post-intervention patient care simulations. Fluorescent lotion and bacteriophage MS2 were rapidly disseminated to touched surfaces throughout the room; there was no difference in the frequency of contamination before versus after the PPE training intervention. After the intervention, there was a decrease in skin and/or clothing contamination with fluorescent lotion (9/30, 30 % versus 1/30, 3 %; P = 0.01) and bacteriophage MS2 (8/30, 27 % versus 2/30, 7 %; P = 0.08) and there was a significant reduction in the concentration of bacteriophage MS2 recovered from hands (0.31 versus 0.07 log10plaque-forming units; P < 0.01).
The researchers say their findings suggest that simulations with fluorescent lotion can be a useful teaching tool to illustrate the spread of pathogens and provide further evidence that simple PPE training interventions can be effective in reducing contamination of personnel.

COVID-19 Harmonization: Balancing Risks and Benefits of CDC's Latest Move
March 11th 2024The CDC's recent decision to align recommendations for respiratory viruses, particularly COVID-19, has garnered support from the public and infectious disease societies. However, as the Infectious Diseases Society of America (IDSA) lends its backing to the CDC's harmonization efforts, concerns persist regarding the implications of this shift, especially considering the Omicron variant's unique characteristics and the ongoing challenges posed by COVID-19's multi-system impacts.

COVID-19 Realities: Beyond a Respiratory Virus, Addressing Optimism in Pandemic Management
February 28th 2024A recent commentary by Dr. Amesh Adalja in MedPage Today challenges the perception of COVID-19 as solely a respiratory virus, highlighting its broader impact on the body. This analysis questions the notion that COVID-19 should be managed like common respiratory infections, urging a closer look at vaccine effectiveness, the rise of long COVID, and the need for enhanced measures to curb the virus's spread. Let's explore the complexities of COVID-19 management and the pressing realities faced by the US and the world.
