“Although many no longer think of COVID being a problem, up to 50,000 Americans died of COVID in [the] 2025-2026 respiratory season and some estimates suggest over 10 million U.S. adults suffer from long COVID. We need to help these patients recover with the best outcomes.”

“This research highlights how much impact the COVID pandemic continues to have on health care workers, with up to one in four still experiencing symptoms following infection. Supporting those affected and preventing similar impacts on health care staff in future pandemics should remain a priority.”

“People from Black, Asian and ethnic minority backgrounds shouldered a disproportionate burden in the COVID-19 pandemic. There is a clear and urgent need for improved workplace adjustments, tailored support for the workforce, and increased learning and understanding of the impact of long COVID for the wider health and care system.”

“We set out looking for a protein that suppresses the immune response, and we found the opposite. It was surprising, but it lines up with what we already know about COVID-19: The virus dampens the immune response early on, then overactivates it later — and that's when a lot of the tissue damage happens.”

“It's critical to keep studying COVID-19 so that we can constantly improve patient care — not everyone responds well to vaccines, and people who are immunocompromised often have limited treatment options. These studies can also help us prepare for future coronavirus outbreaks.”

“This is the largest and most comprehensive biomarker study of COVID-19, in which we followed more than one thousand patients, collected more than 200,000 samples, and generated more than one billion data points over the course of a year for this public resource.”

“Lead author Dr. Amitava Banerjee of University College London in London, U.K., and colleagues investigated whether pre-clinic MRI could identify organ impairment early enough to guide care.”

“The marker of nerve damage used in the study could potentially be used to diagnose long COVID, Jeffrey Meyer, a neurochemist at the University of Toronto, told ScienceAlert. Some people with long COVID might respond to "treatments which either increase the density of dopamine nerve terminals or improve the release of dopamine by the remaining dopamine nerve terminals", said Meyer.”
