by Lancet Credit: The Lancet Diagnostics have proven to be crucial to the COVID-19 pandemic response. A review in The Lancet evaluates the three major methods for the detection of SARS-CoV-2 infection and their role in managing the pandemic. This infographic provides a visual overview of the strengths and weaknesses of molecular (PCR), antigen (lateral flow), and serology...

Deadly ‘black fungus’ disease spotted in Americans with COVID-19
by Ernie Mundell Healthday Reporter It’s a phenomenon first identified in India earlier this year: Patients who have or are recovering from COVID-19 who then contract a sometimes deadly fungal infection known as mucormycosis—also known as “black fungus.” Now, the U.S. Centers for Disease Control and Prevention said isolated cases of the disease are hitting...
Breakthrough infections generate ‘super immunity’ to COVID-19, study suggests

Scientists develop an RNA-based breath test to detect COVID-19
by Elsevier Bubbler kits were processed in a negative pressure bench top box to prevent contamination of amplicon particles in the laboratory. Credit: William G. Fairbrother In a new study in The Journal of Molecular Diagnostics, investigators report on the design and testing of a breathalyzer, known as the Bubbler, that relies on viral RNA detection to...
Molecule from approved malaria medicine protects lung cells against COVID-19
by Aarhus University Credit: Pixabay/CC0 Public Domain Researchers from Aarhus University have shown that the medicine Atovaquone has a protective effect both before and after infection with the coronavirus in human cells in the laboratory. This means that it can in all probability be used both for the prevention and treatment of COVID-19. Atovaquone has already...
Researchers develop potential oral treatment for COVID-19
by Nancy Difiore, Rush University Medical Center Credit: Pixabay/CC0 Public Domain Eugenol, an oily liquid extracted from cloves and a Southeast Asian plant known as holy basil, has been effective in treating mice infected with COVID-19 in a laboratory study, according to newly published research results in the Journal of Neuroimmune Pharmacology. “Eugenol binds to the spike protein of...
Study: How to freeze-dry a potential COVID-19 vaccine
by University at Buffalo The freeze-dried ingredients of a liposome-based vaccine that could be developed for COVID-19. Credit: Douglas Levere / University at Buffalo Things that are freeze-dried: Astronaut food. Emergency rations. And, just maybe, some future COVID-19 vaccines. Freeze-drying is a method for removing water from a product. First, you freeze the item you’re trying...
Scientists solve an important part of the mystery of ultra-rare blood clots linked to adenovirus-based COVID-19 vaccines

Study examines immune responses in patients with kidney failure after receiving different COVID-19 vaccines
Individuals with kidney failure who were on dialysis had an incomplete and delayed antibody response and a blunted cellular immune response following COVID-19 vaccination, compared with people with normal kidney function. Immune responses were substantially stronger with the Moderna mRNA-1273 vaccine than with the PfizerBioNTech BNT162b2 vaccine. A variety of other characteristics also predicted the...
What makes the delta variant of COVID-19 so contagious?
by Nancy Fliesler, Children’s Hospital Boston The Delta variant’s spike proteins fused to cell membranes far more rapidly than those of the five other variants. Credit: DOI: 10.1126/science.abl9463 The delta variant of SARS-CoV-2 has swept the planet, becoming the dominant variant within just a few months. A new study from Boston Children’s Hospital, published in Science, explains...
