Comments closedSome people who had Long Covid early in 2020 are still not well. So the experience of being not listened to and not believed has been very harmful for them alongside the very considerable health impacts that they’ve had from Long Covid. […] The cost of inaction is going to be very high and that’s going to be a human cost and a financial cost.
COVID-19 is a respiratory disease. Yet, from the earliest days of the pandemic, the cardiovascular risks associated with SARS-CoV-2 infection were clear: individuals with severe cases of COVID-19 often died from cardiovascular complications, and those with pre-existing cardiovascular disease were more likely to have severe illness or die.
In short, the cardiovascular system has played a central role in COVID-19 since the beginning.
It is not surprising that as debate over COVID-19 and vaccines flared that cardiovascular disease was a central issue. Those opposed to vaccination often make claims of cardiovascular risks that exceed any benefits. But when data on COVID-19, vaccines and cardiovascular health are reviewed, the conclusions are clear: vaccines are safe and effective at reducing the cardiovascular complications that are a hallmark of COVID-19.
Comments closedTaken together, these studies show that COVID-19 poses a serious risk to brain health, even in mild cases, and the effects are now being revealed at the population level. […]
The growing body of research now confirms that COVID-19 should be considered a virus with a significant impact on the brain. The implications are far-reaching, from individuals experiencing cognitive struggles to the potential impact on populations and the economy.
The proportion of children infected with COVID-19 while riding a bus to a school in Germany was about four times higher than in peers who didn’t ride the bus, illustrating efficient transmission during multiple short rides on public transport, finds a study published this week in Emerging Infectious Diseases.
A team led by researchers from the Robert Koch Institute in Berlin and public health officials used surveillance data, lab analyses, case-patient and household interviews, a cohort study of all students in grades 1 to 4, and a cohort study of bus riders to investigate a 2021 COVID-19 outbreak that involved an infected bus driver and his passengers. The rides lasted 9 to 18 minutes, and multiple schools in a single district were involved.

Comments closedCovid-19 caused the average life expectancy of people worldwide to fall by 1.6 years during the first two years of the pandemic, a more dramatic decline than previously thought, a major study said Tuesday.
This marked a sharp reversal during a decades-long rise in global life expectancy, according to hundreds of researchers sifting through data for the US-based Institute for Health Metrics and Evaluation (IHME).
“For adults worldwide, the Covid-19 pandemic has had a more profound impact than any event seen in half a century, including conflicts and natural disasters,” said Austin Schumacher, an IHME researcher and lead author of the study published in The Lancet journal.
During 2020-2021, life expectancy declined in 84 percent of the 204 countries and territories analysed, “demonstrating the devastating potential impacts” of new viruses, he said in a statement.
The rate of death for people over 15 rose by 22 percent for men and 17 percent for women during this time, the researchers estimated.
Comments closedAverage life expectancy, which has been rising for decades around the world, suddenly declined in 2020 and 2021 at the height of the COVID-19 pandemic, according to a study published on Tuesday in The Lancet.
Life expectancy has declined in the vast majority (84%) of the more than 200 countries and territories studied by the researchers, that is, for all intents and purposes, around the world.
On average, out of all the data reviewed, life expectancy declined by more than a year and a half in 2020-21 (1.6 year). This resulted in an excess of 15.9 million deaths, slightly more than the estimated 15 million estimated by the World Health Organization (WHO) baseline.
Comments closedA study of 1,037,936 US children seen in 17 healthcare systems across the country shows that COVID-19 vaccines are moderately protective against long COVID: 35% to 45%, with higher rates in adolescents. The study was published today in Pediatrics.
The researchers estimated vaccine effectiveness (VE) against long COVID in children aged 5 to 17 years. Though severe COVID-19 cases are less common in children than in adults, persistent symptoms in children do occur.
“It is difficult to establish how much this results from differential reporting of symptoms at different ages, greater difficulty distinguishing long COVID from other childhood illnesses or effects of the pandemic (eg, disruption of seasonal viral patterns, or of school progress,” the authors wrote.
Comments closedCOVID-19 affects men and women differently, with men having greater increases in skin temperature, breathing rate, and heart rate, concludes a study published yesterday in PLOS One.
Researchers in Liechtenstein led the analysis of breathing rate, heart rate, heart rate variability, and wrist skin temperature in 1,163 men and women who wore the Ava medical tracking bracelet while sleeping from April 2020 to January 2022.
Comments closedScientific evidence about the long-term effects of COVID-19 continues to accumulate. Two new studies involving hundreds of thousands of people suggest that SARS-CoV-2 infections can cause cognitive decline.
Researchers at Imperial College, London recruited nearly 113,000 Britons previously infected with the COVID-19 virus for their study. These individuals engaged in various cognitive exercises to assess their memory and their faculties of concentration and attention. Their results were compared to those of people never infected.
The results, published in the New England Journal of Medicine, show that the coronavirus is believed to impair cognitive abilities and the intelligence quotient (IQ).
Comments closedHealthcare workers (HCWs) with long-COVID symptoms reported that their physicians shrugged off their concerns and that they struggled to get the care they needed, a new systematic review suggests.
For the rapid review, published yesterday in PLOS One, researchers from the University of Aberdeen and Robert Gordon University in Scotland reviewed 30 studies published from December 2019 to December 2022 to evaluate the effects of long COVID on HCW health, working life, personal circumstances, and use of healthcare resources. Two of the studies provided qualitative evidence, and 28 survey studies offered quantitative evidence.
Comments closedCOVID-19 may increase the risk of autoimmune inflammatory rheumatic diseases (AIRDs) for up to 1 year after infection, according to a two-country study published today in the Annals of Internal Medicine.
The study, led by researchers from the Broad Institute at MIT and Harvard and from Kyung Hee University in Seoul, South Korea, analyzed national claims databases from more than 10 million Korean and 12 million Japanese patients aged 20 years and older diagnosed as having COVID-19 from January 2020 to December 2021.
The study period was dominated by the wild-type virus and then the Delta variant. The COVID-19 patients were compared with matched flu patients from the same period and uninfected controls.
