PSA: Covid Effects and Complications

Alright fekkers this is how we’re doing public health announcements now that society is collapsing :))

This isn’t a post to tell you to avoid it, but to ask you to read the headings and make sure you make an informed decision if you wanna go out and get infected. If you do take risks, remember to avoid very young/old/pregnant/unwell/vulnerable people, test regularly and wear a mask (yes, they work).

Covid is Not Just A Respiratory Illness

COVID-19 routinely affects organs throughout the body, not just the respiratory system, including the brain, heart, liver, GI tract, endocrine system and skin (Gupta et al., 2020)

Covid can be seen as a blood clotting disorder masquerading as a respiratory illness. (Janardhan et al., 2020)

Covid Causes Brain Damage

Mild Covid infection shows significant orbitofrontal cortical atrophy (shrinking of parts of the brain) and cognitive decline (Crunfli et al., 2022)

Mild COVID-19 infection can cause impaired neurogenesis (nervous tissue growth), myelin and oligodendrocyte (nerve insulation) loss and increased neurotoxic molecules around the central nervous system (Fernández-Castañeda et al., 2022 *preprint)

MRIs of 401 patients done before and after Covid infection showed reduction in global brain size, grey matter loss (orbitofrontal cortex and parahippocampal gyrus) and cognitive decline. (Douaud et al., 2022)

COVID increases the risk of neurodegenerative disorders- Alzheimer’s disease risk is 3.5x increased; Parkinson’s disease risk is 2.6x increased; ischaemic stroke risk is 2.7x increased and intracerebral haemorrhage (bleeding in the brain) risk is 4.8x increased. (Zarifkar et al., 2022)

Risks of cognitive deficit, dementia, psychotic disorders, and epilepsy or seizures are increased for at least 2 years following Covid infection. (Taquet et al., 2022)

In 25% of mild Covid cases, visuocontructive cognitive deficits are seen, associated with changes in brain structure and metabolism. (de Paula et al., 2022)

Hospitalised Covid patients cognitive loss is similar on average to that sustained with 20 years ageing, and equivalent to losing 10 IQ points. (Hampshire et al., 2022)

People reportedly recovered from Covid show decreased intelligence and significant cognitive deficits. (Hampshire et al., 2021)

Covid Causes Alzheimer’s-like Pathology and Accelerates Existing Alzheimer’s Disease

Covid invades cognitive centers of the brain and induces Alzheimer’s-like neuropathology (Shen et al., 2022)

Covid is associated with accelerated progression of Alzheimer’s disease (aaic.alz.org) 

Covid produces proteins that form cytotoxic aggregates which damage neuronal cells, which parallels Alzheimer’s disease mechanism (Charnley et al., 2022)

COVID increases the risk of neurodegenerative disorders- Alzheimer’s disease risk is 3.5x increased; Parkinson’s disease risk is 2.6x increased; ischaemic stroke risk is 2.7x increased and intracerebral haemorrhage (bleeding in the brain) risk is 4.8x increased. (Zarifkar et al., 2022)

Risks of cognitive deficit, dementia, psychotic disorders, and epilepsy or seizures are increased for at least 2 years following Covid infection. (Taquet et al., 2022)

Covid Causes Kidney Damage

Mild Covid infection is associated with increased risk of kidney damage (Bowe et al., 2021)

Covid infection triples risk of End Stage Kidney Disease, requiring dialysis or kidney transplant (Bowe et al., 2021)

Covid Causes Diabetes

Covid patients have a 40% increased risk of being diagnosed with diabetes after first infection (Xie et al., 2022)

Covid infection is associated with an 81% increase in Diabetes incidence for 12+ weeks following infection (Rezel-Potts et al., 2022)

Mild Covid infections increase risk of Type 2 Diabetes development (Rathmann et al., 2022)

Covid infection leads to an average of 42% increased risk of Type 1 Diabetes across all ages. Risk increases most in pediatric patients- by 584%. (Quedan et al., 2022)

Covid Causes Cardiovascular Illness

Covid infection, even when mild, substantially increases risk of cardiovascular illness up to at least 1 year later (Xie et al., 2022)

Capillary density (how many small blood vessels are present) is reduced by 41% in sufferers of Long Covid 18 months after Covid infection (Osiaevi et al., 2022)

Acute Covid infection results in 6x increase in cardiovascular diagnosis; 11x increase in pulmonary embolism (blood clot in lung); 6x increase in atrial arrhythmias (abnormal heartbeat); 5x increase in venous thromboses (blood clot in vein). (Rezel-Potts et al., 2022)

A spike protein found on Covid-19 virus particles uses the body’s immune response to damage and inflame heart muscle cells. (heart.org)

People with Covid exhibited increased risks and 12-month burdens of incident cardiovascular diseases, including cerebrovascular disorders, dysrhythmias, inflammatory heart disease, ischemic heart disease, heart failure, thromboembolic disease and other cardiac disorders. Risk were evident even in those without prior cardiovascular disease. (Xie et al., 2022)

Risk of stroke more than doubles even with mild or asymptomatic Covid infection. Median time of stroke is 2 months after Covid diagnosis. (Tu et al., 2021)

Covid infection increases heart attack risk by 3-8x and stroke risk by 3-6x (Katsoularis et al., 2021)

Covid infection increases risk of deep vein thrombosis, pulmonary embolism and bleeding in the months following acute illness (Katsoularis et al., 2022)

Long Covid is associated with presence of microclots throughout the body. (Pretorius et al., 2021)

Long Covid patients may face an increased risk of abnormal blood clotting. (uclh.nhs.uk)

Covid Accelerates Biological Ageing

Accelerated biological ageing is seen in Covid infection (Cao et al., 2022)

Covid Damages the Immune System

Covid causes T-cell exhaustion, meaning the immune system is less able to fight off pathogens (Loretelli et al., 2021)

Previous infection with earlier SARS2 strains can lead to impaired immune responses to Omicron (Reynolds et al., 2022)

Covid infects and kills T-lymphocytes (key cells of the immune system), causing low T-lymphocyte counts 1(Guan et al., 2020), 2(Shen et al., 2022)

Long Covid patients show reactivation of latent Epstein-Barr (can cause MS) and Varicella Zoster (can cause shingles and Ramsey Hunt syndrome) viruses (Klein et al., 2022 *preprint)

2.8% of Long Covid patients reported Varicella Zoster Virus reactivation, leading to shingles, following Covid infection. Primary risk factors for VZV reactivation are age and immunodeficiency. (Davis et al., 2021)

Covid infection causes immunodefiency in recovered patients by downregulating a specific protein on B Cells (a type of immune cell). (Jing et al., 2021)

Covid Causes the Body to Attack Itself (Autoimmunity)

Covid causes production of autoantibodies which target the immune system, vascular cells, coagulation factors and platelets, connective tissue, and organ systems, including lung, the central nervous system compartment, skin, gastrointestinal tract and other tissues. (Wang et al., 2021)

Asymptomatic Covid infection can lead to severe Ulcerative Colitis (an inflammatory bowel disease). (Mora et al., 2022)

Mild Covid infection can produce significant levels of autoantibodies for 7+ months. (Bhadelia et al., 2021)

Covid infection precedes new appearance of autoimmune and inflammatory diseases. (Galleoti and Bayry, 2020)

Covid infection linked to development of vasculitis, arthritis, lupus and sarcoidosis. (Gracia-Ramos et al., 2021)

Autoantibodies linked to Lupus, Rheumatoid Arthritis, Guillain-Barré syndrome, immune thrombocytopaenia and autoimmune haemolytic anaemia found in patients following Covid infection. (Moody et al., 2021)

In a group of non-hospitalised healthcare workers with Covid, 54% tested positive for autoantibodies- these targeted skin, smooth muscle, neutrophils (a type of white blood cell of the immune system) and gastric parietal cells (cells in the gut). (Richter et al., 2021)

Covid May Affect Both Male and Female Fertility

COVID-19 virus can be found and continues to replicate in the testes even after death (Costa et al., 2022 *preprint)

COVID-19 infects the testes and damages spermatogenesis (sperm production) (Ma et al., 2020)

Covid virus particles found in penis tissue of men infected 6-8 months earlier, who later experienced erectile dysfunction (Kresch et al., 2021)

Study shows total sperm number lower in men infected with Covid at 3 month follow up (Best et al., 2021)

Testes of Covid patients show significant seminiferous tubular injury and reduced Leydig cells- cells that produce testosterone. (Yang et al., 2020)

11 of 26 (42%) men with mild/moderate Covid infection showed incidental (asymptomatic) epididymitis on Doppler ultrasound - a condition that can cause infertility (Carneiro et al., 2021)

A case of premature ovarian failure due to Covid infection (Madaan et al., 2021)

Another case of premature ovarian insufficiency in a 34-year-old following Covid infection (Wilkins and Al-Inizi, 2021)

Ovarian injury, including declined ovarian reserve and reproductive endocrine disorder, can be observed in a study of women in China infected with Covid. (Ding et al., 2021)

Study finds men who had seemingly fully recovered from Covid infection developed decreased sperm count and motility and abnormally shaped sperm. (Ghosh et al., 2022)

Covid Causes Erectile Dysfunction

Covid virus particles found in penis tissue of men infected 6-8 months earlier, who later experienced erectile dysfunction (Kresch et al., 2021)

A Long Covid survey found 15% of men reported sexual dysfunction and 3% reported a decrease in genital size. (Davis et al., 2021)

Prevalence of erectile dysfunction 3x as common in men after Covid infection (28% vs 9% in controls) (Sansone et al., 2021)

Prevalence of erectile dysfunction in Thai men reported as 65% following Covid infection (Harirugsa et al., 2021)

Another study showing risk of erectile dysfunction triples following Covid infection. (Katz et al., 2021)

Study finds that Covid infection leads to 6-fold increased risk of erectile dysfunction, which worsens men’s mental health. (Hsieh et al., 2022)

Covid Causes Autonomic Nervous System Dysfunction

30% of 4000 Long Covid patients met the criteria for a diagnosis of Postural Orthostatic Tachycardia Syndrome, a type of dysautonomia (Davis et al., 2021)

Dysautonomia (autonomic nervous system dysfunction) may be responsible for fatigue and hypoxia in Long Covid patients. (Barizien et al., 2021)

Covid infection frequently causes abnormalities in autonomic nervous system tests, as well as worsening pre-existing dysfunction. Abnormalities included orthostatic intolerance, fainting, heachaches, burning pains, excessive sweating and lightheadedness. (Shouman et al., 2021)

67% of Long Covid patients have moderate-to-severe autonomic dysfunction, regardless of severity of initial Covid infection. (Larsen et al., 2022 *preprint)

Covid infection could result in gastric dysmotility and paralysis (stomach and intestines become unable to move food through). (Coles et al., 2022)

Covid Can Seriously Harm Children

SARS2 causes increased hospital admissions, mortality rate and absolute numbers of deaths in children, compared to Influenza (Shein et al., 2022)

Asymptomatic infection in children can lead to a serious, multiorgan hyperinflammatory syndrome (Riphagen et al., 2020)

An epidemic of hepatitis in healthy children could be linked to previous COVID-19 infection (science.org)

Pulmonary dysfunction persists even in children considered to be recovered from Covid (Heiss et al., 2022 *preprint)

Covid leads to a 3x increased risk of psychotic disorders in children (Taquet et al., 2022)

Children are twice as likely to develop epilepsy or seizures following Covid infection, compared to following other respiratory infections (Taquet et al., 2022)

Children are at an increased risk of epilepsy, encephalitis, nerve, nerve root and plexus disorders up to at least 2 years after Covid infection (Taquet et al., 2022)

Intracranial (brain) bacterial infections have increased during the Covid pandemic, occuring during or just after Covid infection. One Michigan children’s hospital reports a 236% increase. (Khuon et al., 2022)

235,000 children in England have Long Covid symptoms lasting 12+ weeks that affect their daily life (ONS.gov.uk)

21% of Year 13 pupils missed 4+ weeks of school due to Covid for the 21/22 academic year in England (suttontrust.com)

Children and teens who’ve had Covid are at greater risk for blood clots, heart problems, kidney failure, and Type 1 diabetes (Kompaniyets et al., 2022)

5.2 million children have lost a parent or caregiver to Covid infection. (Unwin et al., 2022)

Covid infection leads to an average of 42% increased risk of Type 1 Diabetes across all ages. Risk increases most in pediatric patients- by 584%. (Quedan et al., 2022)

Covid Can Endanger Pregnancy and the Growing Baby

Covid infection during pregnancy increases risk of preterm delivery (Edlow et al., 2022)

Covid infection at delivery increases risk of stillbirth (DeSisto et al., 2021)

Covid infection during pregnancy increases risk of neurodevelopmental disorder diagnosis in babies by 2.17x during first year of life (Edlow et al., 2022)

Risk of severe Covid infection is higher in pregnant women. (Rad et al., 2021)

Newborns born to mothers who had recovered from Covid 10+ weeks prior to birth show viral mRNA and proteins in their stool and signs of intestinal inflammation. (Jin et al., 2022)

Covid infection destroys the placenta, starving the baby of oxygen, resulting in increased risks of stillbirth and neonatal deaths. (Schwartz et al., 2022)

Covid Can Lead to Development of New Allergies

Mast cell activation syndrome (MCAS) may be triggered by Covid infection, resulting in new allergies and risk of anaphylaxis. (Afrin et al., 2020)

Mast cell activation symptoms are increased in Long Covid (Weinstock et al., 2021)

Covid Worsens Mental and Psychological Health

Covid diagnosis associated with increased risk of mental health diagnosis and neurocognitive decline (Xie et al., 2022)

Risks of cognitive deficit, dementia, psychotic disorders, and epilepsy or seizures are increased for at least 2 years following Covid infection. (Taquet et al., 2022)

Covid Reinfection is Common and Increasingly Detrimental to Health

Reinfection with Covid increases risk of hospitalization, death and long covid by more each time 1(Al-Aly et al., 2022 *preprint), 2(World Health Organisation)

Covid reinfections are common. Mean time between 1st and 2nd infection is 79 days, and between 2nd and 3rd infection is 65 days. (Al-Aly et al., 2022 *preprint)

Covid reinfection is possible as soon as 19 days after initial infection. (Ren et al., 2022)

Long Covid is Common, Serious and Potentially Disabling

1 in 5 (20-30%) develop a new health condition following Covid infection (Bull-Otterson et al. 2022)

Just below 1 in 10 (9.3%) triple vaccinated people are not recovered 4-8 weeks after Omicron infection in the UK (ONS.gov.uk)

1 in 7 (14%) of 11-18 year olds have symptoms 15 weeks after COVID-19 infection (Stephenson et al., 2021)

Long Covid causes disability and unemployment (theguardian.com)

On average, healthcare staff absent with Long Covid are off for more than 80 days in England (theguardian.com)

A US Long Covid group reports that 44% of those affected are out of work (longhauler-advocacy.org)

235,000 children in England have Long Covid symptoms lasting 12+ weeks that affect their daily life (ONS.gov.uk)

21% of Year 13 pupils missed 4+ weeks of school due to Covid for the 21/22 academic year in England (suttontrust.com)

Vaccination Does Not Fully Prevent Long Covid

16% of Covid infections lead to Long Covid after 3 vaccinations (Azzolini et al., 2022)

Just below 1 in 10 (9.3%) triple vaccinated people are not recovered 4-8 weeks after Omicron infection in the UK (ONS.gov.uk)

Vaccination only reduces risk of Long Covid by 15%. (Al-Aly et al., 2022)

Covid Persists in the Body after Initial Infection

Covid can persist throughout the body and brain even following mild/asymptomatic infections, for at least 230 days (Chertow et al., 2021 *preprint)

COVID-19 can persist within the gut for at least 7 months after infection 1(Gaebler et al., 2021), 2(Natarajan et al., 2022)

Covid virus particles found in penis tissue of men infected 6-8 months earlier, who later experienced erectile dysfunction (Kresch et al., 2021)

Viral Persistence Can Cause Serious Illness Many Years Later

We do not know the long term effects of Covid Infection and Persistence.

Persistent Hepatitis C infection increases risk of Hepatocellular carcinoma (liver cancer) (Mitchell et al., 2015)

Persistent Human Papillomavirus (HPV) infection causes cervical cancer (Sudenga et al., 2013)

Persistent HIV infection leads to immunodeficiency and AIDS (Pauza, 1988)

Persistence of Epstein Barr Virus (EBV) can cause development of multiple sclerosis (Ruprecht, 2020)

Persistence of varicella zoster virus (VZV), which causes chickenpox, can result in shingles and Ramsey Hunt Syndrome (Gershon et al., 2015)

These effects of Covid are not easy to learn about, but it is essential that people know the risks. This is not fearmongering- it is not “what if”s and “maybe”s- these are events that are happening right now, around the world.

Weekly COVID-19 Update for 2023-12-24

COVID is still airborne, and COVID still very much isn't over.

Northeastern and Midwestern USA SARS2 virus levels in wastewater are *soaring*, Northeast is currently at 1500 copies/mL (~750 copies indicates a strong surge), and Midwest is at 1300 copies/mL. Southeastern and Western USA are maintaining relatively lower levels between 600 and 700 overall, but both are still climbing. See https://biobot.io/data for county-specific data as results can vary widely between locales.

How to reduce your risk of infection? The SARS2 virus is airborne and can spread like smoke, so #MaskUp with an #N95 or better, avoid superspreader events and locations, and stay up-to-date on your boosters. Do it for yourself, so you don't catch SARS-CoV-2, and for others, so you don't spread SARS-CoV-2. Even if you're fully vaccinated, your risk of developing #LongCOVID following an infection is lower but not zero, and multiple reinfections increase your odds of negative health outcomes. Plan A always should be to prevent an infection from developing by wearing a respirator with a good seal around your mouth and nose (FFP2, FFP3, KN95, N95, N99, P100, etc.).

Holiday tips:

-If someone tells you that COVID is over, you might ask them why, if we didn't consider COVID to be over in 2020 or 2021, when the COVID wastewater levels were lower, why should we consider it over now, when the virus is circulating in even higher amounts?

-"Fewer cases" doesn't mean much when most of the at-home rapid tests don't get counted in official records, and the most accurate PCR tests are neither freely available nor given to everyone getting on a plane or attending classes.

-"Fewer deaths" also means less when you remember that about 1,200,000 of the most vulnerable people already have died from it, COVID-19 remains the #3 cause of death in 2023 (behind heart disease and cancer, the risk of both of which may be increased by COVID), and the risk of a Long COVID/post-acute COVID syndrome (PACS) disability or other potentially life-shortening organ damage (brain, kidney, lung, immune, etc.) isn't measured just by the death count. Also, the USA's life expectancy still hasn't recovered from the drop it experienced following the start of the pandemic.

Researchers find deer carry SARS-CoV-2 variants that are extinct in humans

Cornell University researchers have found that white-tailed deer—the most abundant large mammal in North America—are harboring SARS-CoV-2 variants that were once widely circulated, but no longer found in humans.

Whether or not deer could act as long-term reservoirs for these obsolete variants is still unknown, as scientists continue to collect and analyze new data.

The study, published January 31 in the journal Proceedings of the National Academy of Sciences, represents one of the most comprehensive studies to date to assess the prevalence, genetic diversity and evolution of SARS-CoV-2 in white-tailed deer.

"One of the most striking findings of this study was the detection of co-circulation of three variants of concern—alpha, gamma and delta—in this wild animal population," said Diego Diel, associate professor of population medicine and diagnostic sciences at Cornell.

Over the course of the pandemic, deer have become infected with SARS-CoV-2 through ongoing contact with humans, possibly from hunting, wildlife rehabilitations, feeding of wild animals or through wastewater or water sources.

The Role of Bacterial Pneumonia in the Severity of the 1918 Influenza Pandemic - TheRadicalScholar.com

The 1918 influenza pandemic stands as one of the most devastating outbreaks in human history. With millions of lives lost, understanding the

🌡️⚖️ Bacterial Pneumonia: Lessons from the Past, Relevance to COVID-19 🦠🔍

The 1918 influenza pandemic taught us about the significant role of bacterial pneumonia, overshadowing the primary viral infection. This knowledge remains relevant to COVID-19.

🧪 Unveiling the Evidence: Autopsy findings showed that secondary bacterial infections were the primary cause of death during the 1918 pandemic.

⚙️ Viral-Bacterial Interplay: Combining influenza viruses with bacteria led to severe disease, highlighting their synergistic effects.

💡 Pandemic Preparedness: Recognizing the importance of bacterial pneumonia is vital in preparing for future outbreaks. Preventing, diagnosing, and treating bacterial pneumonia should be prioritized.

😷 Finding Balance: While masks are essential in curbing the spread of COVID-19, excessive and indiscriminate usage may have drawbacks. Research has raised concerns about certain mask types potentially increasing respiratory infections.

💪 Navigating Complexity: We need a comprehensive approach that balances mask usage with overall health considerations to create a resilient society.

🌍🤝 Building a Healthier Future: By learning from history, we can prioritize public health, prepare for future pandemics, and minimize unintended consequences. Let's stay vigilant and #StopTheSpread.
