Scientists spot viruses attaching to other viruses for first time

By Michael Irving November 05, 2023A transmission electron microscope image of a satellite virus attached to a helper virus, a phenomenon which has never been seen before Tagide deCarvalhoScientists have discovered that viruses can latch onto other viruses to insert their genes into host cells. Lab results with apparent contamination led the team to directly see...

COVID-19’s long reach: Some physical symptoms can persist up to two years post-diagnosis

By Pooja Toshniwal Paharia Oct 31 2023 Reviewed by Danielle Ellis, B.Sc. In a recent study published in The Lancet Regional Health-Europe, researchers investigated the prevalence rate of physical-type symptoms by the severity of acute coronavirus disease 2019 (COVID-19) beyond two years of diagnosis. Study: COVID-19 illness severity and 2-year prevalence of physical symptoms: an...

Is Long Covid Brain Fog Connected to Gut Health? A New Study Offers a Startling Hypothesis

By Caroline Burke Getty Images Buckle up for a surprisingly exciting crash course on serotonin. The results of a new study on long Covid are out, and they’re more than promising — they might even be groundbreaking. Conducted by researchers at the University of Pennsylvania, the study suggests there may be a strong connection between serotonin...

Number of People With Long COVID Could Be Vastly Underestimated

Megan Brooks It’s been estimated that up to one third of people who survive acute SARS-CoV-2 infection will suffer a post-viral syndrome with lingering neurologic and other symptoms — now known as long COVID or neurological postacute sequelae of SARS-CoV-2 infection (Neuro-PASC). However, new research suggests that may be an underestimate and that far more...
