Science: Test sensitivity is secondary to frequency and turnaround time for COVID-19 screening

The COVID-19 pandemic has created a public health crisis. Because SARS-CoV-2 can spread from individuals with presymptomatic, symptomatic, and asymptomatic infections, the reopening of societies and the control of virus spread will be facilitated by robust population screening, for which virus testing will often be central. After infection, individuals undergo a period of incubation during which viral titers are too low to detect, followed by exponential viral growth, leading to peak viral load and infectiousness and ending with declining titers and clearance. Given the pattern of viral load kinetics, we model the effectiveness of repeated population screening considering test sensitivities, frequency, and sample-to-answer reporting time. These results demonstrate that effective screening depends largely on frequency of testing and speed of reporting and is only marginally improved by high test sensitivity. We therefore conclude that screening should prioritize accessibility, frequency, and sample-to-answer time; analytical limits of detection should be secondary.

Archived Briefings from Protect Our Province BC

In honor of February being Heart Month, cardiologist Dr. Leslie Kasza joined Protect our Province BC’s Dr. Susan Kuo for a discussion on COVID-19’s impact on heart health and how you can reduce your risk. Don’t be fooled into thinking it won’t happen to you because you are _________, fill in the blank: young, healthy vaccinated and/or you only had a mild infection, etc.
A Protect Our Province BC panel discussion about how we as a community, can pull together to create a safer learning environment for kids when school starts again in September! We can avoid another ‘tripledemic’ if we work together! Ready for Fall 2023? Briefing video:
“COVID-19 vaccination is safe during pregnancy and may protect newborns from infection, especially if vaccines are given in the second or third trimester. This is similar to what we are already doing with other maternal vaccines, including TDaP and seasonal influenza.” – Dr. Eastabrook

No lessons were learned. This year, despite the lessons that could have been learned and implemented, BC public health was as ill prepared as it was last year for the viral "respiratory season”. * And so on January 9, a new record number of hospital admissions was set at 10,345 . For more up to… Continue reading State of Public Health in BC

Alberta Mom Photo: @BerlinBuyers My first confirmed Covid infection was in fall 2022 at a time when the few Covid protections we had left only applied to healthcare settings. I knew I was at higher risk of developing Long Covid as I am a working age woman. This terrified me as my son had already had… Continue reading No One is Listening to Me
