Coronavirus (COVID-19)
News and updates on the novel coronavirus, COVID-19.
-
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.
-
A new study has found that an extract made from willow bark, the precursor to aspirin, possesses effective broad-spectrum antiviral properties. The discovery may mean we will soon have a new way of fighting viral infections like colds and flu.
-
Anyone who has been on the planet for the last four years will know how viruses that evolve to jump across species can rapidly become a serious global crisis. Researchers now believe we're in an alarming new age of vertebrate animal-to-human infections.
