Coronavirus (COVID-19)
News and updates on the novel coronavirus, COVID-19.
-
A new study may explain the variable severity of SARS-CoV-2 from person to person. Using AI-driven machine-learning researchers discovered the virus is broken down into fragments, and this debris resembles peptides that overstimulate the immune system.
-
Using a virus-mimicking DNA scaffold instead of the usual protein one to deliver a vaccine to mice not only generated a robust immune response but avoided the off-target effects sometimes seen when proteins are used.
-
Researchers have identified a blood protein ‘signature’ in the complement system, part of the immune system, of patients with long COVID that may improve the diagnosis and lead to a treatment for the debilitating condition.
-
The first study of its kind has looked at every UK resident – more than 67 million people – across four months, and found that, as vaccine uptake tapered off in 2022, 7,180 hospitalizations and deaths could have been avoided had jabs been up to date.
-
Exercise is usually a good thing but for many long COVID patients it can often make their condition worse. Two new studies are shedding light on this counter-intuitive phenomenon, finding distinct physiological abnormalities in long COVID patients.
-
Researchers have developed a novel intranasal COVID-19 vaccine that enhances the immune system’s response to the virus, providing longer-lasting, greater protection than vaccine injections, even against new and emerging variants.
-
Researchers developed an AI algorithm that automatically analyzes chest X-rays to rapidly detect COVID-19 infection with more than 98% accuracy, distinguishing between normal X-rays and X-rays from people with viral pneumonia.
-
A new study has found the BA.2.86 variant of SARS-CoV-2 has a greater propensity for infecting certain lung cells than any prior Omicron variant. The research suggests BA.2.86 could potentially lead to COVID severity similar to the Delta variant.
-
Researchers have developed a novel anti-inflammatory from a Southeast Asian medicinal plant that doesn’t suppress the immune system like currently used corticosteroids do, opening the door to a new class of anti-inflammatory drugs.
-
Researchers have developed a powdered vaccine that's inhaled directly into the lungs for an effective immune response. The vaccine can deliver multiple antigens, meaning one dose could provide broad-spectrum protection against several respiratory viruses.
-
New research is the first to reveal microstructural brain changes in long COVID patients compared to fully recovered patients and uninfected subjects. The findings indicate long COVID symptoms can be associated with changes to specific cerebral networks.
-
Researchers have found that SARS-CoV-19 infection can cause ‘zombie’ cells to accumulate, contributing to the brain fog associated with long COVID, and have identified drugs that can reverse this virus-related premature aging.
