Many infectious diseases, including COVID-19, are transmitted by airborne pathogens. There is a need for effective environmental control measures which, ideally, not reliant on human behaviour. One potential solution Krypton Chloride (KrCl) excimer lamps (often referred to as Far-UVC), which can efficiently inactivate pathogens, such coronaviruses and influenza, in air. Research demonstrates that when KrCl filtered remove longer-wavelength ultraviolet emissions they do induce acute reactions...
Bacterial transmission from contaminated surfaces via hand contact plays a critical role in disease spread. However, the fomite-to-finger transfer efficiency of microorganisms during multiple sequential surface contacts with and without gloves has not been formerly investigated. We measured quantity Escherichia coli on fingertips participants after 1-8 inoculated plastic coupons nitrile gloves. A Bayesian approach was used to develop mechanistic model pathogen accretion examine finger...
Self-contamination during doffing of personal protective equipment (PPE) is a concern for healthcare workers (HCW) following SARS-CoV-2-positive patient care. Staff may subconsciously become contaminated through improper glove removal; so, quantifying this exposure critical safe working procedures. HCW surface contact sequences on respiratory ward were modeled using discrete-time Markov chain for: IV-drip care, blood pressure monitoring, and doctors' rounds. Accretion viral RNA gloves care...

Hospital-acquired infections (HAIs) are a global challenge incurring mortalities and high treatment costs. The environment plays an important role in transmission due to contaminated air surfaces. This includes microorganisms' deposition from the onto Quantifying rate of microorganisms enables understanding surface contamination can inform strategies mitigate infection risk. We developed validated novel Automated Multiplate Passive Air Sampling (AMPAS) device. sequences passive samples be...
