Many types of tests are available for COVID-19 for clinical and public health use (see the figure). Testing can be performed in a central laboratory, at the point of care (POC), or in the community at the workplace, school, or home. COVID-19 testing begins with specimen collection. For medical use, a nasopharyngeal swab collected by a health care professional has been used for detection of virus infections. Demands on testing throughput for COVID-19, however, have driven new collection approaches, including saliva and less invasive nasal swabs. COVID-19 tests include molecular tests such as qPCR, isothermal amplification, and CRISPR, as well as antigen tests that detect SARS-CoV-2 proteins directly. Although rapid antigen tests have lower analytical sensitivity (i.e., require greater amounts of virus material to turn positive) than qPCR-based tests, their ability to detect infectious individuals with culturable virus is as high as for qPCR (3). Specificity (i.e., correctly identifying those not infected with SARS-CoV-2) of antigen tests achieves comparable results to molecular tests (4).

Archived Briefings from Protect Our Province BC
As we start a new school year, clean air in schools is a vital issue not only because of the health effects from the ongoing COVID-19 pandemic and air pollution, but because of the direct link to the ability of children to learn. Hear about the new recommendations for Indoor Air Quality in Schools and Childcare Facilities from Vancouver Coastal Health and Fraser Health.
“For some of the most vulnerable patients, the air in the hospital can be deadlier than the diagnosis that brought them in”
Join Protect our Province BC and Drs. Susan Lee, Jean Warneboldt, and Victor Leung to hear about their advocacy, their struggles and successes in improving the air quality in different BC Health Authorities. Why are different healthcare administrations within BC treating this critical topic so differently - in one, obstructing and blocking and in another rewarding and awarding?
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.

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
