It’s not just about pollution; it's about what the air carries.
A new study (April 2026) in BMC Infectious Diseases highlights the ongoing risk of SARS-CoV-2 reinfections. #SafeSchools 7/
Every wave we ignore adds to the cumulative neurological damage. 📉⚠️
To break this cycle, we need more than just filters. We need Far-UVC (222nm).

Part 1: The Invisible Thief How Air Quality Shapes Our Brains We often think of air quality as a future problem. New research shows it’s an ongoing crisis for our brains from the womb to old age. 2/
The evidence is stacking up: clean air isn't just about breathing; it's about thinking.
A heartbreaking study in @Guardian reveals that babies exposed to air pollution during pregnancy take longer to learn to speak.

We often hear the claim that children aren't affected by Long COVID or that it's extremely rare.
A new study published in @Nature (Scientific Reports) following children and adolescents through 2023 tells a different story. 🧵⬇️ #ChildHealth #SafeSchools #CleanAir 2/
The study found a Long COVID incidence rate of 8,5%.
That nearly 1 in 10 children suffering from persistent symptoms. This is not "pandemic stress"—it is a physiological consequence of the virus. 📉⚠️

New evidence confirms that SARS-CoV-2 can reach the fetus through the amniotic fluid. This isn't just about maternal health; researchers have now detected the virus directly within fetal organs, including the lungs and intestines.
Here’s why this changes the conversation. ⬇️ 2/
How does it happen? The study highlights "amniotic infection." When a pregnant person is infected, the virus can enter the amniotic fluid. As the fetus naturally swallows this fluid, the virus gains a direct pathway into the fetal digestive and respiratory systems. 💧🦠

The long term heart risks of C-19 💔 A massive new study in the European Heart Journal confirms what many feared: SARS-CoV-2 is not just a respiratory virus. It’s a long-term cardiovascular threat. The risk of major heart events remains elevated for years after infection. 2/
Here is what the data shows ⬇️
Researchers tracked over 10,000 individuals and found that a COVID-19 infection is associated with a significantly higher risk of MACE (Major Adverse Cardiovascular Events), including heart attack and stroke, for up to three years post-infection.

New science from bioRxiv (10.64898/2025.12.31.697156) shows that asthma isn't just a "reaction"—it's a fundamental destruction of our airway's molecular program. Our lungs are being physically rewritten by chronic exposure. 🧵👇 The #LeonardiEffect is very real! 2/
Crucially, the study highlights how T-cells become dysfunctional and drive permanent scarring (remodeling). But there's more: research from MedUni Wien confirms that SARS-CoV-2 infections cause long-term damage to our entire immune system. 🫁⚠️

Is SARS-CoV-2 more than just a respiratory virus? Emerging research is raising a chilling question: Could COVID-19 be an oncovirus? Recent studies suggest the virus may interfere with our body’s ability to prevent and fight cancer. Let’s dive into the science. 🧬👇 #Cancer 2/
A key study in Nature shows that the SARS-CoV-2 spike protein can inhibit DNA damage repair. It blocks the recruitment of critical proteins like BRCA1 and 53BP1 to repair sites. If our DNA can’t fix itself, mutations accumulate: the first step toward cancer.

Following the thread on the cumulative risk of Long COVID in children after reinfection, let's look at a new study on vaccination and adults. The evidence is overwhelmingly clear: vaccination is protective. #VaccinesWork #PublicHealth 2/
A massive Swedish nationwide study (Sahlgrenska Academy, European Heart Journal) of over 8 million adults confirms that full COVID-19 vaccination significantly reduces the risk of severe cardiovascular conditions linked to the infection.

🚨 The Double-Edged Sword: New research suggests #SARSCoV2 might be an unseen accelerant for #LungCancer. Beyond acute illness, the virus's long-term effects could fuel cancer development and progression. This is a critical public health warning. 👇 #COVID19 #Oncology 2/
The study highlights several terrifying potential mechanisms:
Chronic Inflammation: The cytokine storm and persistent, dysregulated inflammation after COVID are well-known cancer promoters.

Marie Ewerz is 49. She got COVID in 2021 and has not been well since. Her symptoms are getting worse. 💔 Thousands in Sweden still suffer from a condition—Long COVID—that remains largely misunderstood, years after the first cases. Marie says: "You feel so alone."
@SwedishPM 2/
The illness has fundamentally changed her family life. At 9, her son first found her passed out on the kitchen floor. "He's been terrified and barely dared to leave me," Marie shares. Now 13, his worry meant he’s had to grow up too fast.

A new study on #LongCovid in children shows worrying results. Researchers found a strong link between persistent neuropsychiatric symptoms (like headaches, dizziness, and memory issues) and changes in brain volume, specifically in the temporal and subcortical regions. 2/
The study published in Pediatric Neurology found that children with more severe symptoms during the acute phase of COVID-19 were more likely to have significant brain volume changes months later. This suggests that the initial severity of symptoms can predict long-term effects

A new Swedish study from the Public Health Agency suggests that for healthy, low-risk seniors and young adults in risk groups, the cost-effectiveness of COVID-19 vaccination is low. According to the study, the benefit is limited from a socioeconomic perspective.
@SwedishPM 2/
The study states that the most significant benefits are for seniors in high-risk groups, those with home care, or living in nursing homes. For these groups, the vaccine is even cost-saving for society.

A disturbing study from late 2020 revealed something we should all be paying attention to: virtually all children infected with COVID-19 showed signs of blood vessel damage. #COVID19 #PublicHealth 2/
This was seen even in asymptomatic kids. The study from Children's Hospital of Philadelphia found a "high proportion" showed elevated levels of a biomarker tied to blood vessel damage.

Long COVID and returning to work: A difficult and frustrating path. Many who got sick on the job are still unemployed, with their workers' compensation claims in limbo. New studies suggest the problem affects more workers than previously thought. #LongCovid #WorkersRights 2/
Around 16 million workers nationwide have been affected by Long COVID. Many face the extra burden of proving they were infected at work to qualify for workers' comp, which covers employees injured or sickened on the job.

Myths and misinformation about #COVID19 and children have been rampant since the start of the pandemic. It’s time to debunk the dangerous idea that kids are immune to severe illness, long-term health problems, and can't spread the virus. #PublicHealth #BackToSchool 2/
While children are often more resilient than adults, that doesn't mean they're immune to serious health issues from a COVID-19 infection. Emerging data shows risks are growing as reinfections increase, especially in the least-vaccinated age groups. #KidsHealth #Vaccines

New research from Rutgers Health highlights the critical need for vigilance when observing #LongCovid symptoms in young children. The study, part of the NIH RECOVER initiative, shows that infants, toddlers, and preschoolers can get long COVID, #COVID19 #Pediatrics 2/
but their symptoms often differ from older children.
Symptoms like fussiness, poor appetite, difficulty sleeping, and coughing were more common in the youngest group, making it easy for clinicians & caregivers to miss the diagnosis. #PublicHealth

Clean air should be as fundamental a right as clean water. It's a basic necessity for health, yet often overlooked. We need to prioritize respiratory health for everyone, especially our most vulnerable. The long-term effects of airborne viruses like #CleanAir #HealthyFutures 2/
SARS-CoV-2 are still emerging, especially concerning our children. Data indicates 10-20% of children who get COVID-19 may develop Long COVID (PASC), potentially affecting up to 5.8 million children in the US alone. #LongCOVIDKids #KidsHealth

Universities, schools and daycares are failing their students on #LongCOVID. It's time they step up, protect students, and reduce #COVID19 cases. The situation at Stanford is a harsh example. 🧵 #UniversitiesFailStudents #LongCOVIDAction 2/
Toward the end of a student’s final year at Stanford (2023), they developed chronic neurological symptoms after a mild Covid infection - muscle twitches, numbness & cognitive dysfunction – all signs of Long Covid. Naturally this affected their academic performance.

It's clear: Long COVID is significantly impacting children. A new study from the University of Otago reveals over a fifth of kids and teens suffer persistent symptoms after COVID-19. This isn't just a cough; it's headaches, fatigue, and new anxieties. #LongCovidKids 2/
The study, published in the International Journal of Paediatrics and Child Health, surveyed 4200+ children aged 3-20. More than 70% had confirmed COVID-19. A quarter reported more frequent coughs, colds, and stomach aches post-infection. #COVID19 #PublicHealth

The history of medicine is filled with brilliant minds whose groundbreaking discoveries were met with fierce resistance. Why do established beliefs so often trump new, life-saving facts? Let's talk about it. #MedicalHistory #ScienceDenial #PublicHealth 2/
Think of Ignaz Semmelweis. In the 1840s, he figured out that doctors washing their hands drastically reduced childbed fever deaths. His simple solution saved lives, but was ridiculed and rejected by the medical establishment of his time. #Semmelweis #HandHygiene

A common misconception: children need infections to build strong immune systems. Prof. Jörn Klein explains this is false. It's exposure to harmless microbes in nature – not illnesses like measles or flu – that truly strengthens immunity. #ChildHealth #ImmuneSystem 2/
The "hygiene hypothesis" is often misinterpreted. It's not about being "too clean," but a lack of diverse microbial exposure. Children thrive with a rich microbial life around them, from soil, animals & nature, which doesn't cause illness. #Microbiome #HealthyKids
