COVID-19: Increased risk of dying from infection and sudden death

This a long thread looks at several studies on death and neurovascular injury along with a whole bunch of sudden death examples of relatively young and healthy people found by @MeetJess. 🧵1/ German heart patient in med...
The problem is that COVID-19 is not just a respiratory virus, it can get into many different systems and organs in your body and cause vascular damage leading to many different outcomes and severities. Image from:… 2/ Different parts of the body...
Infected patients develop blood clots, heart inflammation, arrhythmias, and heart failure among others (… ). 3/
A study that performed autopsies on the brains of COVID-19 patients who died shortly after infection found all patients had multifocal vascular damage in the brain which was accompanied by widespread endothelial cell activation (… ). H/T: @MeetJess 4/
"Antibody-mediated cytotoxicity directed against the endothelial cells is the most likely initiating event that leads to vascular leakage, platelet aggregation, neuroinflammation and neuronal injury." 5/
Another study found that hospitalized patients who survived at least a week after being discharged were more than twice as likely to die or be admitted to hospital again within months compared to the general population (… ). H/T: @MeetJess 6/
These COVID-19 patients also had increased risk for readmission, adverse mental health and cognitive outcomes and a 5x higher risk of dying from all-cause mortality in the following 10 months. 7/
The Ministry of Health (MoH) in Singapore released this very interesting report on excess deaths over the weekend ( ). "In a secondary analysis of persons without recent infection, no additional excess deaths were found." 8/
Non-COVID excess deaths could be explained by patients who passed away from other illnesses within 90 days of being infected with COVID-19, showing COVID-19 aggravated existing illnesses, resulting in further mortalities (… ). 9/
It is not just adults that die from COVID-19. A recent study in Japan looked at 41 children under the age of 20 who were infected and died between January and August of this year, 73% within a week after symptom onset (… ). H/T: @KatePri14608408 10/
So much for Omicron being mild, more than half the children who died developed COVID-19 symptoms after mid-July (within the past 2 months). 11/
More than half (52%) of the children did *not* have any underlying medical conditions, and 87% of the children who were eligible for vaccines were *not* vaccinated, all of the 18 children under 5 who died were unvaccinated. 12/
"The main causes of death were 'circulatory system abnormalities' including myocarditis and arrhythmia in seven patients, or 24%, and 'central nervous system abnormalities' such as acute encephalopathy in another seven patients. Among others were multiorgan failure." 13/
Now onto the many examples of sudden death recently in the news that @MeetJess has compiled in 5 threads. With so many people becoming infected without protections in place, how many could have been from a COVID-19 infection in the past 12 months ( )? 14/

PHO is reminding HCWs, even those who have been vaccinated, to wear an N95 while providing care to people with confirmed or suspected cases because they know N95s can prevent infection from infectious aerosols. Works for other airborne viruses as well and non-HCW too.
Respirators protect individuals who are healthy and help reduce the chance of individuals who are sick from infecting others even in well ventilated places where short-range transmission is a concern. 2/

Right now the JN.1 and JN.1.4 Pirola variant are still the most prevalent.
