NewsScientists uncover shared biology behind profound fatigue in five major illnesses
New research identifies a shared biological secret that helps explain chronic exhaustion in conditions including long Covid and PTSD.

NewsStudy finds that cognitive decline after omicron infection is largely reversible
Cognitive problems, often described as “brain fog,” are a recognized feature of long COVID, affecting attention, memory, and executive function. Earlier SARS-CoV-2 variants, including the original strain, Alpha and Delta, were associated with persistent cognitive deficits. However, the Omicron variant caused less severe disease, leaving uncertainty about whether cognitive decline ...

NewsRECOVER-VITAL clinical trial finds no benefit of extended duration of PAXLOVID for Long COVID
Results from a clinical trial show that the antiviral drug, PAXLOVID, commonly prescribed to treat acute COVID-19, does not have an impact on Long COVID symptoms when compared to placebo.

NewsSevere COVID-19 reactivates dormant viruses, study finds
Better understanding of how these activated viruses contribute to COVID-related outcomes could help physicians better predict potential complications and improve treatment for patients with severe COVID infection.

NewsA lesser-known SARS-CoV-2 protein may offer clues to long COVID symptoms
A new study describes a previously unrecognized way the SARS-CoV-2 nucleocapsid protein can push the immune system into dangerous overdrive.
-
NewsNight shift work linked to a higher risk of long COVID
People working night shifts were nearly twice as likely to develop long COVID, while chronic insomnia further increased the risk, according to a study based on the COVICAT cohort.
-
NewsCommonly used drugs show small benefit for long Covid fatigue
Over-the-counter antihistamines and a prescription anti-inflammatory drug both have a small benefit in reducing long Covid fatigue among people receiving care from specialist long Covid clinics, according to new findings from a large clinical trial.

NewsCOVID’s lingering shadow faded after Omicron — but not for everyone
A long-term study of long Covid has found that whilst lingering symptoms became far less common after the Omicron variant arrived, some people have continued to experience health problems years after infection.
-
NewsDiabetes worsens long COVID complications
In a study involving 870 participants, people with diabetes took longer to recover from the virus and experienced more severe cardiac complications, as well as greater physical and cognitive difficulties.
-
NewsMetformin given during acute COVID-19 infection reduced risk of clinician-diagnosed long Covid by 50%
New findings from the ACTIV-6 randomized clinical trial provide important confirmation of prior clinical trial results that metformin, a widely available and inexpensive medication with an established safety record, reduced the risk of clinician-diagnosed long COVID when started during acute COVID-19 infection.
-
NewsAntibody clues could improve long Covid care and prognosis
Researchers have found that SARS-CoV-2 antibody patterns may help assess infection history, symptom severity, and cognitive complications in long Covid.
-
NewsScientists validate a link between autoimmunity in a subset of people with long COVID
A research team has demonstrated that autoimmunity, where the body’s immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of people.
-
NewsLong Covid burden continues to grow, doubling current surveillance estimates, multi-hospital study shows
Investigators using a novel AI algorithm to comb through medical records of patients with COVID-19 in U.S. hospitals, found around one in six developed long COVID. These rates are twofold higher than current estimates.
-
NewsBrain inflammation is unlikely to explain persistent long COVID symptoms
A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection. Instead, the most severe long COVID symptoms were associated with increased brain activity in regions involved in mood and emotion.
-
NewsFlawed but correctable research hindered progress in infection-triggered chronic conditions
Researchers contend that studies of infection-associated chronic illnesses such as Lyme disease and COVID-19 suffer recurring problems such as the failure to prove participants have the relevant pathogen.
-
NewsWhy feeling sick may be important for surviving infection
In a new perspective, scientists propose a different way of thinking about sickness symptoms: what if these behaviors are part of an integrated immune strategy that operates across scales — from individual cells to tissues and organs, to the whole organism — and helps promote survival?
-
NewsLong COVID associated with increased risk of cardiovascular disease
People with long COVID are at increased risk of developing cardiovascular disease, according to a new study. Women with long COVID had just over twice the risk of receiving a cardiovascular diagnosis compared with women without long COVID. Men had approximately a third higher risk.
-
NewsAutoantibodies implicated as drivers of long COVID in new study
A new study shows that antibodies from Long COVID patients can induce persistent pain-like symptoms in mice. This provides evidence for a potential causal role of autoantibodies in Long Covid.
-
NewsStudy details neuropsychiatric symptoms and biological mechanisms of long COVID
A review highlights the need to standardize diagnosis and treatment of long Covid. In the study, the researchers emphasize that avoiding SARS-CoV-2 infection is the only way to prevent long COVID so far.

NewsTrial finds vitamin D supplements don’t reduce Covid severity but could reduce long COVID risk
In a large, randomized trial, researchers have found that high-dose vitamin D3 did not reduce COVID-19 infection severity, but may impact long COVID outcomes.
