Using retrospective epidemiological data, Japanese researchers found that spread was very low during the games, as most cases occurred during arrival or mandatory quarantines before the games.

Novel anti-inflammatory drug shows early promise in treating Long COVID cognitive symptoms, fatigue, PEM. The study looked at multiple endpoints and consulted with people living with the disease.

Low-dose prednisolone may temporarily reduce some “symptom severity” of Long COVID, according to a new study in eClinicalMedicine. German researchers evaluated the drug, a corticosteroid that reduces inflammation and is used to treat a broad range of conditions, alongside some B vitamins, in the phase 3 clinical trial.

Changing seasons affect many people with Long COVID, myalgic encephalomyelitis, and other chronic illnesses, but not all in the same way. Research has a long way to go before it can explain the phenomenon.

A large Long COVID review found mechanisms of “accelerated biological aging” in young adults. The review was published in Ageing Research Reviews and synthesized 110 mechanistic and epidemiological Long COVID studies on adults ages 25–55.

A new study found COVID-19 was linked to a significant increase in dementia in older people with type 2 diabetes. The retrospective study published in Frontiers in Aging Neuroscience included a cohort of nearly half a million people with documented SARS-C0V-2 infections.

Researchers, clinicians, and advocates gathered for the inaugural conference of the International Society for Long COVID and Post-Acute Infection Syndromes in the Netherlands in late August. The four-day event featured hundreds of presentations and posters about trials and disease mechanisms.

As many as 2.3 million new cases of cancer were triggered by viral infections worldwide in 2024, according to new research in The Lancet Oncology. French researchers analyzed a large database of cancer incidence from 2024, looking at specific diagnoses that were attributable to infections.

A small clinical trial found Remdesivir was safe for people with Long COVID and that some exploratory results warrant a larger trial. The U.K. trial, which included 73 participants who took a five day course of the intravenous antiviral COVID-19 drug, was published in Oxford Open Immunology.

The trial, run by researchers at McMaster University in Canada, is testing the Lightning Process, a pseudoscientific mind-body program that outside experts have heavily criticized.
