Introduction: Long COVID syndrome (LCS) is characterized by persistent neurological, respiratory, and systemic symptoms following SARS-CoV-2 infection, with limited effective treatments available. Viu...

Objective Endothelial and microvascular dysfunction are key features of Long COVID. Disturbances in cellular redox balance, reflected by altered nicotinamide adenine dinucleotide (NAD+/NADH) dynamic...

Hundreds of millions of people have long-term conditions as a result of an infection. Researchers are working out how to help them.

Most individuals with PCC recover, but older adults and those with multiple symptoms are at higher risk of prolonged illness, underscoring the need for ongoing support.

Background Post-COVID-19 syndrome is a major long-term sequela of severe SARS-CoV-2 infection, potentially involving persistent angiogenic and thromboinflammatory dysfunction, though long-term biomark...

Virus reactivations by SARS-CoV-2 could worsen initial symptoms and increase risk of Long Covid

Post-COVID-19 Syndrome (PCS) encompasses a range of persistent symptoms, including cognitive and autonomic disturbances, potentially linked to microva…

Persistent symptoms after SARS CoV-2 infection, often designated as "long COVID”, continue to be an ongoing health issue. Previously, we reported elec…

The skeletal consequences of COVID-19 have emerged as an important but still underrecognized component of post-viral systemic disease. Increasing clinical, e...

While prolonged neuroinflammation is considered a hallmark of Post Acute Sequelae of COVID-19 (PASC), its basis is poorly understood. The authors here manifest infiltration of peripheral myeloid cells...

Background Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating, multi-systemic condition that has gained renewed global attention due to its clinical overlap with the growing...

Persistent cardiac symptoms are common in post-COVID syndrome. In the Myoflame-19 trial, losartan plus prednisolone yielded neutral results for the primary outcome, change in left ventricular ejection...

Ma et al. perform deep-phenotyping of CD8+ T cells specific for viruses implicated in LC pathogenesis: SARS-CoV-2, CMV, and EBV. These T cells from LC individuals share features of terminal differenti...

Pediatric Research - Endothelial activation and thromboinflammation in Long COVID: revisiting the vascular axis in pediatric populations

Long COVID, or Post-Acute Sequelae of SARS-CoV-2 infection (PASC), affects a significant proportion of COVID-19 survivors and is associated with persistent fatigue, dysautonomia, and cardiovascular co...

IntroductionMyalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and long COVID have overlapping symptoms, such as profound fatigue, cognitive impairm...

Translational Psychiatry - Fatigue after COVID-19 infection is associated with peripheral immunometabolic alterations affecting neuroimmune responses in the hippocampus

Introduction Long COVID and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) are relatively common and disabling multisystem disorders that share overlapping features, including post-infect...

Cognitive dysfunction is one of the most prevalent symptoms in patients with post-COVID condition (PCC) and episodic memory has been highlighted as one of the most impaired cognitive domains in these ...

People who live with Long COVID and are trying to remain part of the workforce need to know their rights. […]

Critics of the Daily Show host say he's a hypocrite.

This study aimed to analyze the clinical features and infection status of COVID-19 patients with bacterial infections in Shaanxi Province. A...

COVID-19 is associated with increased risks of neurological and psychiatric sequelae. Alternative polyadenylation (APA) is ubiquitous in human genes, resulting in mRNA diversity, and has been validate...

Objective The objective was to estimate unique patterns of change in fatigue in people with the Post-Covid Syndrome (PCS) over 15 months. Design/Subjects The Quebec Action for Post-COVID (QAPC) study...

A major consequence of the COVID-19 pandemic has been the emergence of post-COVID syndrome (PCS), and more specifically, post-COVID fatigue (pCF), with an estimated prevalence of ∼2%. We previously sh...

Medscape News Canada leverages the most-read Canadian stories in 2025 and makes a list of the five that generate the most interest and, in some cases, controversy.

The widespread presence of microplastics (MPs) in the air and their potential impact on human health underscore the pressing need to develop robust me…

COVID-19 does not just affect the respiratory system, but also significantly alters the brain in people who have fully recovered from the infectious

It remains elusive whether the T cell repertoire will cover all point mutations of a major epitope. The authors here show that COVID vaccine–induced CD8⁺ T cells detect most YLQ peptide variants excep...

The largest study so far into the genetics of chronic fatigue syndrome, or myalgic encephalomyelitis, has implicated 259 genes – six times more than those identified just four months ago

COVID-19 does not just affect the respiratory system, but also significantly alters the brain in people who have fully recovered from the infectious

This would require finding study subjects who never had Covid and never took the vaccine.
