Producing ratio measures of effect with quantitative microbial risk assessment
June 2022

QMRA has proven to be a useful framework for estimating infectious disease risks associated with various human exposures; however, integration of QMRA with existing epidemiological frameworks is constrained by disparate endpoint measures. Here we propose a method for producing traditional epidemiology measures of effect using QMRA.

Application of digital PCR for public health-related water quality monitoring
April 2022

Digital polymerase chain reaction (dPCR) is emerging as a reliable platform for quantifying microorganisms in the field of health-related water microbiology. This paper reviews the fundamental principles of dPCR and its applications for health-related water microbiology.

Passive sampling to scale wastewater surveillance of infectious disease: Lessons learned from COVID-19
April 2022

In response to the COVID-19 pandemic, passive sampling is re-emerging as a promising technique to monitor SARS-CoV-2 RNA in wastewater. Herein, we briefly review the history of wastewater passive sampling, recent applications during the COVID-19 pandemic, including comparisons between passive, grab, and composite sampling, along with the potential benefits and constraints of passive sampling workflows.

Detection of the Omicron (B.1.1.529) variant of SARS-CoV-2 in aircraft wastewater
January 2022

We putatively detected the Omicron variant in an aircraft wastewater sample from a flight arriving to Darwin, Australia from Johannesburg, South Africa on the 25th of November 2021 via positive results on the CDC N1, CDC N2, and del(69–70) RT-qPCR assays per guidance from the WHO. The Australian Northern Territory Health Department detected one passenger onboard the flight who was infected with SARS-CoV-2, which was determined to be the Omicron VOC by sequencing of a nasopharyngeal swab sample.
