More than 70% of US household COVID spread started with a child, study suggests

According to a recent study, over 70% of nearly 850,000 US household COVID-19 transmissions originated with a child. The researchers concluded that children had an important role in the spread of SARS-CoV-2, and that in-person school also resulted in substantial spread.

CAMH study confirms ongoing brain inflammation associated with long COVID

A new Centre for Addiction and Mental Health (CAMH) study found elevated levels of inflammation in the brains of patients who report persistent symptoms of long COVID.

Using advanced brain scanning with positron emission tomography (PET), the researchers found elevated levels of the protein TSPO, a brain marker of inflammation, in patients with onset of depression within several months after a COVID-19 infection.

Astronomy Tool Can Now Detect COVID in Breath

Researchers are investigating a promising technique that may be used to check for the presence of SARS-CoV-2. A frequency comb involves the use of lasers to look for volatile organic compounds (VOCs) that are associated with COVID infections.

Masks Work. Distorting Science to Dispute the Evidence Doesn’t

Masks work. Especially respirator-style N95 masks.

Amid an ongoing pandemic and outbreaks of influenza and RSV caused by airborne viruses, arguing over the virus-blocking power of masks remains one of the COVID era’s signature follies. Disconcertingly, despite decades of evidence of their efficacy, some of the disagreement comes from a few in the medical field itself, misusing science and endangering lives.

Rapid Progression of Dementia Following COVID-19

In a new study, researchers examined the cognitive impacts of COVID-19 on people with dementia. They found that having COVID-19 rapidly accelerated the structural and functional brain deterioration of patients with dementia, regardless of the type of dementia being experienced.

Are repeat COVID infections dangerous? What the science says

Nature

April 26, 2023

“People with repeat infections were twice as likely to die and three times as likely to be hospitalized, have heart problems or experience blood clots than were people who were infected only once. In a surprising twist, vaccination status didn’t seem to have an impact — although other studies show vaccines to be protective. Whether these results hold true for the general population is up for debate. The Veterans Affairs cohort was made up mostly of older white men, which is not representative of the wider population.”

Covid infection could speed up progression of dementia, new study finds

A new study, published in the Journal of Alzheimer’s Disease Reports, has discovered that infection with SARS-CoV-2 (the virus that causes Covid) has a significant impact on cognitive function in patients with pre-existing dementia.

Over 10% of children in Japan with COVID-related brain disease died, survey finds

More than 10% of children in Japan who developed acute brain syndrome after infection with COVID-19 have died, results of a nationwide survey recently announced by a health ministry research team has shown.

The survey identified 34 cases of acute encephalopathy associated with COVID-19 infection among those under 18 between January 2020 and May 2022. The team analyzed 31 patients who did not have any underlying illnesses that could be responsible for causing the brain disease.

Beyond the pandemic: Long COVID emerges as a silent crisis

[I]t appears that, regardless of gender and other demographic factors, COVID-19 infection at baseline is correlated with increased problems with emotion regulation six months later: depression, anxiety and agitation.

La COVID longue, un mal invisible (mais bien présent)

The majority of people experience extreme fatigue and many suffer post-stress discomfort, a kind of energy crash. Brain fog, lack of concentration and memory loss are also common symptoms.

Some people develop conditions and syndromes such as postural orthostatic tachycardia syndrome (POTS), characterized by dizziness and palpitations when a person is in a upright position. Others develop dysautonomia, which causes palpitations, pressure rises or falls, dizziness and gastric problems.

Long COVID: 3 years in

March 11 marks 3 years since WHO declared COVID-19 to be a pandemic. While the world is determined to move on from the acute phase, at least 65 million people are estimated to struggle with long COVID, a debilitating post-infection multisystem condition with common symptoms of fatigue, shortness of breath, and cognitive dysfunction, impairing their ability to perform daily activities for several months or years. Although the majority of patients infected with SARS-CoV-2 recover within a few weeks, long COVID is estimated to occur in 10–20% of cases and affects people of all ages, including children, with most cases occurring in patients with mild acute illness. The consequence is widespread global harm to people’s health, wellbeing, and livelihoods—an estimated one in ten people who develop long COVID stop working, resulting in extensive economic losses.

Long COVID linked to lower brain oxygen levels, cognitive problems and psychiatric symptoms

We are the first to show reduced oxygen uptake in the brain during a cognitive task in the months following a symptomatic COVID-19 infection. This is important because a lack of sufficient oxygen supply is thought to be one of the mechanisms by which COVID-19 may cause cognitive impairment.

Κορωνοϊός: Οι περισσότεροι ασθενείς με long Covid εμφανίζουν βλάβες οργάνων ένα χρόνο μετά

More than half of patients with long Covid suffer from organ damage a year after the initial symptoms, new research suggests.

Even those who were not seriously ill when diagnosed with the virus report problems, with extreme difficulty breathing and cognitive impairment among the persistent symptoms.

The study, the results of which were published in the Journal of the Royal Society of Medicine, involved 536 people.

Six months after their initial diagnosis with coronavirus, the patients underwent an MRI scan which revealed ongoing health problems, with 62% of participants suffering from organ damage.

Do Repeat COVID Infections Increase the Risk of Severe Disease or Long COVID?

Many repeat infections are mild, but some studies suggest people who have been infected with COVID more than once are at a greater risk of severe disease or long COVID.

Yes, masks reduce the risk of spreading COVID, despite a review saying they don’t

There is strong and consistent evidence for the effectiveness of masks and (even more so) respirators in protecting against respiratory infections. Masks are an important protection against serious infections.

COVID-19 is a leading cause of death in children and young people in the US

For the one-year period August 1, 2021, to July 31, 2022, COVID-19 was a leading cause of death in children and young people in the United States, ranking eighth overall.

The researchers believe that vaccines and nonpharmaceutical interventions are needed to limit transmission of SARS-CoV-2, and mitigate severe disease.
