Covid-19 is not just a respiratory infection. Cardiovascular symptoms are seen in both acute and long covid. Katharine Lang reports on what we’ve learnt since the onset of the pandemic Cardiovascular complications from covid-19 have been seen widely since the early days of the pandemic, when a small study in Wuhan reported myocardial injury in several patients.1 Soon after, studies found that up to 30% of those admitted to intensive care units showed myocardial injury.23 “In many respects covid-19 is a vascular disease masquerading as a respiratory one,” says Andy Benest, vascular biologist at the University of Nottingham. Although covid is transmitted through the respiratory system, much of the pathology unfolds in the vascular system, with microvascular damage, thromboinflammation, and dysregulated perfusion underpinning the cardiac, pulmonary, and neurological manifestations of severe disease. “The virus enters through the airways but exerts its systemic effects through the vasculature, the common denominator in the lungs, heart, kidneys, and brain,” Benest tells The BMJ . Cardiovascular complications are relatively common in the acute phase of covid. Studies have found that acute cardiac injury occurred in 6-25% of people admitted to hospital with covid.4 One 2020 study reported that 14.1% of people admitted to hospital with covid experienced some type of cardiovascular complication.5 Early studies suggested that the endothelium …

The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer’s disease and greater levels of dementia, a new study finds.

"Study shows impaired energy metabolism in the brains of people with post-COVID" Brain fog, poor concentration and slowed thinking in Long COVID patients are linked to altered brain energy metabolism, with MRI studies showing changes that correlate with worse cognitive test performance.

The new British research is the first to reveal striking differences in areas of the brain based on scans taken before and after a coronavirus infection.

Coronavirus not only infects the human retina, but can also replicate in it

A picture is emerging of the toll long Covid takes inside the body and why it can be so debilitating.

Nature - Like adults, children can experience long COVID, but few studies of the condition include young people. That has to change.

Even without a positive COVID test, lasting symptoms can persist for months. A new study challenges assumptions about recovery and urges broader support for COVID-like illnesses.

In this collection, you may notice sometimes conflicting reports: that's because that's how science *works* - more and more data is collected, then meta-analysis are performed to weed out lesser quality studies and determine the highest known accuracy to move forward to the *next stage. Note that even when a vaccine performed even statistically *slightly* under expecations (J&J) they *immediately* pulled it from the market. BECAUSE THATS HOW SCIENCE WORKS.

The CDC is beginning to look at death certificates that indicate more than 100 people who died had long Covid.

In this prospective, life-spanning, nationally representative cohort study, LRTI during early childhood was associated with almost a two times increased risk of premature adult death from respiratory disease, and accounted for one-fifth of these deaths.
