Taking metformin during SARS-CoV-2 infection cuts risk of long COVID in clinical trial
People who took the diabetes drug metformin after being infected with SARS-CoV-2 were less likely to develop long COVID in a randomized clinical trial. Read More
Quantification of long COVID fatigue shows impact is worse than some cancers
Fatigue is the most impactful symptom in the lives of people suffering from long COVID, with patients reporting worse scores than individuals with some cancers. Read More
Long COVID symptoms reported by 17% of unvaccinated people
Swiss researchers have found that about 17% of unvaccinated people report experiencing COVID-19-related health problems up to two years after SARS-CoV-2 infection. Read More
Cryo-electron microscopy sheds light on key step in replication of SARS-CoV-2
Researchers have used cryo-electron microscopy (cryo-EM) to visualize a critical step in the replication of SARS-CoV-2, generating insights that could inform the development of COVID-19 drugs. Read More
COVID-19’s ‘long tail’ analyzed at European rheumatology congress
Researchers have found that people with inflammatory rheumatic diseases show no increased susceptibility to long COVID. This and other studies are being presented at the European Alliance of Associations for Rheumatology (EULAR) 2023 Congress in Milan from May 31 to June 3. Read More
FDA grants full approval for antiviral pill to treat mild-to-moderate COVID-19 in adults

Medical records link vaccination against COVID-19 to reduced risk of non-respiratory symptoms
Fully vaccinated individuals had a lower risk of dying or developing some non-respiratory symptoms than people without protection against COVID-19 during the Delta and Omicron waves, a retrospective review of medical records has found. Read More
A closer look at long COVID symptoms
Patients with persistent neurological symptoms after SARS-CoV-2 infections were intensively studied and found to have autonomic dysfunction and differences in their immune cell profiles. The findings, published last Friday in Neurology: Neuroimmunology & Neuroinflammation, may help explain lingering long-COVID neurological symptoms, and lead to better diagnoses and treatments.

Targeting viral RNA to treat infection
Despite the rapid development of COVID-19 vaccines, the rise of variants forces scientists to frequently modify treatments. A new study published Wednesday in ACS Central Science describes a treatment that directly targets and degrades the viral ribonucleic acid (RNA) genome, reducing SARS-CoV-2 infection in mice.
