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.Read More
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.Read More
Infectious SARS-CoV-2 found in hospital air Quebec researchers isolated infectious SARS-CoV-2 virus particles from air samples that were originally collected from COVID-19 patients’ hospital rooms, then kept frozen for more than a year.Read More
Rapid nirmatrelvir treatment may reduce long COVID risk A study of people with SARS-CoV-2 infection who had at least one risk factor for progression to severe disease found that treatment with nirmatrelvir within five days of a positive SARS-CoV-2 test result was associated with reduced risk of post−COVID-19 condition, known as long COVID. The findings, published Thursday in JAMA Internal Medicine, held true across the risk spectrum in this cohort, regardless of vaccination status and history of prior infection.Read More
