Coronavirus (COVID-19)
News and updates on the novel coronavirus, COVID-19.
-
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.
-
Striking new findings have demonstrated how all variants of virus that causes COVID-19 can spread into the brain and travel from neuron to neuron. This indicates losing one's sense of smell is not necessarily linked to the virus infiltrating the brain.
-
Many assumed asthmatic children would be more prone to severe COVID-19 infection, but a new study suggests that, compared to children who don’t have asthma, those with the condition are not at greater risk of serious COVID infection.
-
New research reveals the severity of COVID-19 may be linked to a fungal population living in our gut, and perhaps novel antifungal medicines can be developed to treat the disease.
-
A study has found that non-COVID respiratory infections can lead to ‘long’ symptoms that persist well beyond the acute infection stage. The findings increase awareness about the existence of long-lasting respiratory infections other than long COVID.
