The Delta variant may have dashed hopes of herd immunity, but we can still live with the virus. Authors: DAVID LIVERMORE During the winter and spring the swiftly developed vaccines began to show startling success. Deaths from Covid fell, and severe side effects were rare. The UK rollout was among the most efficient in the […]

A new study found that the most educated are the least likely to get jabbed Authors: RAY HALL The percentage of each education group that is somewhat vaccine hesitant. Source: Carnegie Mellon University There has been much debate over how to get the unvaccinated to get their jabs — shame them, bribe them persuade them, or treat them as victims […]

Posted on | Posted on John Murphy | Leave a Comment on Early COVID-19 symptoms differ among age groups, research finds

Authors: King’s College London Symptoms for early COVID-19 infection differ among age groups and between men and women, new research has found. These differences are most notable between younger age groups (16 to 59 years) compared to older age groups (60 to 80 years and over), and men have different symptoms compared to women in […]

Age-Adjusted Associations Between Comorbidity and Outcomes of COVID-19: A Review of the Evidence From the Early Stages of the Pandemic

Posted on | Posted on John Murphy | Leave a Comment on Age-Adjusted Associations Between Comorbidity and Outcomes of COVID-19: A Review of the Evidence From the Early Stages of the Pandemic

Authors: Kate E. Mason*, Gillian Maudsley, Philip McHale, Andy Pennington, Jennifer Day and Ben Barr Objectives: Early in the COVID-19 pandemic, people with underlying comorbidities were overrepresented in hospitalised cases of COVID-19, but the relationship between comorbidity and COVID-19 outcomes was complicated by potential confounding by age. This review therefore sought to characterise the international evidence base available in the early stages […]

The Age-Related Risk of Severe Outcomes Due to COVID-19 Infection: A Rapid Review, Meta-Analysis, and Meta-Regression

Posted on | Posted on John Murphy | Leave a Comment on The Age-Related Risk of Severe Outcomes Due to COVID-19 Infection: A Rapid Review, Meta-Analysis, and Meta-Regression

Authors: Karla Romero Starke 1, Gabriela Petereit-Haack 2, Melanie Schubert 1, Daniel Kämpf 1, Alexandra Schliebner 1, Janice Hegewald 1, Andreas Seidler 1 Abstract Increased age appears to be a strong risk factor for COVID-19 severe outcomes. However, studies do not sufficiently consider the age-dependency of other important factors influencing the course of disease. The aim of this review was to quantify the isolated effect of age on […]

Potential for False Positive Results with Antigen Tests for Rapid Detection of SARS-CoV-2 – Letter to Clinical Laboratory Staff and Health Care Providers

Posted on | Posted on John Murphy | Leave a Comment on Potential for False Positive Results with Antigen Tests for Rapid Detection of SARS-CoV-2 – Letter to Clinical Laboratory Staff and Health Care Providers

Authors: FDA The U.S. Food and Drug Administration (FDA) is alerting clinical laboratory staff and health care providers that false positive results can occur with antigen tests, including when users do not follow the instructions for use of antigen tests for the rapid detection of SARS-CoV-2. Generally, antigen tests are indicated for the qualitative detection […]

Antigen and Molecular Tests

Posted on | Posted on John Murphy | Leave a Comment on Antigen and Molecular Tests

Diagnostic tests are used to detect current, active infections of the SARS-CoV-2 virus. Diagnostic tests can be antigen based (“rapid antigen” tests), which look for protein markers on the outside of the virus, or they can be molecular based (including PCR, LAMP, CRISPR), which look for viral genomic material specific to SARS-CoV-2. Molecular based tests that amplify […]
