The groundbreaking research of Linsey Marr, an aerosols expert and professor of civil and environmental engineering at Virginia Tech, showed that the SARS-CoV-2 virus is airborne as opposed to traveling in large droplets that fall with gravity.

Scientists behind mRNA COVID Vaccines Win 2023 Nobel Prize in Physiology or Medicine
This year’s Nobel Prize in Physiology or Medicine goes to a transformative medical technology that significantly altered the path of the pandemic and saved millions: the mRNA vaccines against COVID. Katalin Karikó and Drew Weissman were jointly awarded the prize for advancements that have changed the field of vaccine development and researchers’ understanding of how messenger RNA (mRNA) interacts with the body’s immune system.

Sepsis associated with COVID-19 infections more common than thought
Today in JAMA Network Open, researchers provide new evidence that the prevalence of SARS-CoV-2–associated sepsis among hospitalized adults is higher than previously thought, but deaths from the condition became less frequent as the pandemic progressed.

SARS-CoV-2 can infect coronary arteries and trigger heart attack, stroke, study suggests
SARS-CoV-2 can directly infect the arteries of the heart, inflaming the fatty plaque inside and raising the risk of heart attack and stroke, suggests a small study published yesterday in Nature Cardiovascular Research.

SARS-CoV-2 infects coronary arteries, increases plaque inflammation
SARS-CoV-2, the virus that causes COVID-19, can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke, according to a study funded by the National Institutes of Health. The findings, published in the journal Nature Cardiovascular Research, may help explain why certain people who get COVID-19 have a greater chance of developing cardiovascular disease, or if they already have it, develop more heart-related complications.

People with Long COVID Have Distinct Hormonal and Immune Differences From Those Without This Condition
Long COVID patients have clear differences in immune and hormone function from patients without the condition, according to a new study led by the Icahn School of Medicine at Mount Sinai and Yale School of Medicine.
The research, published in the September 25 issue of Nature, is the first to show specific blood biomarkers that can accurately identify patients with long COVID.

Long Covid: MRI scans reveal new clues to symptoms
People living with long Covid after being admitted to hospital are more likely to show some damage to major organs, according to a new study.
MRI scans revealed patients were three times more likely to have some abnormalities in multiple organs such as the lungs, brain and kidneys.

Does the risk of getting long Covid increase each time you get reinfected?
More than three years into the coronavirus pandemic, fewer and fewer people are experiencing their first Covid-19 infections. But as cases climb, those who’ve had the virus before may wonder: What are their chances of developing long Covid — and does the risk increase with each reinfection?

1 in 4 COVID survivors had impaired lung function 1 year on, study shows
A quarter of COVID-19 survivors had impaired lung function 1 year after infection, and older patients, those with more than three chronic conditions, and those with severe cases improved slower than other patients over time, a Dutch study published yesterday in PLOS One reveals.

Restrictions likely helped curb spread of COVID-19 in N.S., Dalhousie researchers find
A new report from six Dalhousie University researchers has found government restrictions that limited movement during the first two years of the pandemic likely helped curb the spread of COVID-19.
It also found infection, hospitalizations and deaths increased when restrictions eased and the highly infectious Omicron variant arrived.

COVID patients exhale up to 1,000 copies of virus per minute during first eight days of symptoms
COVID patients exhale high numbers of virus during the first eight days after symptoms start, as high as 1,000 copies per minute, reports a new Northwestern Medicine study.

High levels of 2 blood-clotting proteins may portend post-COVID brain fog
High levels of two blood biomarkers during infection could predict cognitive dysfunction, or “brain fog,” among COVID-19 survivors 6 and 12 months after hospitalization, according to a UK study published yesterday in Nature Medicine.

Blood Clotting Proteins Might Help Predict Long COVID Brain Fog
Many people who have long COVID—a condition in which health issues persist months after infection—report struggling with “brain fog,” recurring memory and concentration lapses that make it difficult to function in everyday life. Now a new study has found these cognitive problems could result from blood clots triggered by infection, possibly through mechanisms like those that cause some types of dementia. These clots leave telltale protein signatures in blood, suggesting that testing for them could help predict, diagnose and possibly even treat long COVID.
