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 Image
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 Image
3/
Historically, infections were the leading cause of child deaths. The dramatic decline in child mortality is thanks to improved hygiene, vaccination, and antibiotics, not children becoming "stronger" by getting sick. #PublicHealth #VaccinesWork Image

Crucially, infections don't protect against allergies or autoimmune diseases. In fact, some viruses (like RSV & measles) can increase the risk of asthma, allergies, or even damage the immune system's memory, making kids more vulnerable. #InfectionPrevention #HealthFacts Image
5/
Frequent early infections pose unnecessary risks. Research shows each infection before age three can increase the need for antibiotics or risk of more severe illness later in life, particularly respiratory infections. #EarlyChildhood #ProtectKids Image
6/
And remember: clean air is vital! Protecting children from infections also means ensuring they breathe clean air, both indoors and out. Good ventilation & reducing pollution are key defenses for their developing lungs. #CleanAirNow #EnvironmentalHealth Image
7/
Vaccines offer a safe way to build immunity without the child getting sick. Healthcare professionals emphasize: children aren't stronger from illness, but from a safe, varied environment, good hygiene, infection control, and vaccination. #VaccineSafety #ParentingTips Image

Every infection is an unnecessary risk. Children's immune systems are strengthened by growing up in a secure environment with contact with animals, nature, and other children – alongside protection through vaccination.

A new report from Sweden highlights a staggering 62% increase in Type 1 Diabetes diagnoses for children under 5 between 2018-2022. Experts suggest the #COVID19 pandemic may have heavily impacted immune systems.

This stands in stark contrast to earlier Swedish claims that children were unaffected.

During the height of the pandemic, certain Swedish voices, like Prof. Jonas Ludvigsson, claimed "Children do not die" from
Covid-19.

This narrative pushed for open schools and "herd immunity," with Ludvigsson even asking them if he could quote them on "no school outbreaks."

New analysis reveals a stark reality: 1 in 5 COVID-19 survivors still battle symptoms 3 years after severe infection. This meta-analysis of 11 studies highlights the profound, lasting effects on health and quality of life. #LongCovid #PostCovid Image
2/
The most common persistent symptoms include fatigue, sleep disturbances, and shortness of breath. These aren't just minor annoyances; they significantly impact daily living and long-term well-being. #ChronicIllness #HealthCrisis Image

This research, published in the Journal of Medical Virology, evaluated data from over 142,000 patients across Europe, Asia, and Australia, predominantly focusing on those hospitalized in 2020. The numbers are sobering. #MedicalResearch #PublicHealth Image

New research reveals a concerning link: prenatal SARS-CoV-2 exposure might impact a baby's brain development. This isn't just about acute illness; it's about potential long-term effects on cognitive, communication, & motor skills. #COVID19 #ChildDevelopment #PublicHealth Image
2/
The study looked at babies whose mothers had COVID-19 during pregnancy. At 6 months, many showed delays. By 24 months, those delays were even more common: nearly 65% had communication delays, and over 57% had motor delays! This is serious. #PediatricHealth #LongCOVID Image
3/
What's the connection? Researchers found that specific immune markers (cytokines and chemokines) in cord blood at birth were linked to these developmental delays. Things like IFN-γ, TNFα, IL-6, IL-8, IL-17, IL-1β, and CXCL10. These could be early warning signs. #Biomarkers Image

🚨 New research from Karolinska Institutet reveals a stark truth: newborns facing severe health issues in their first weeks (respiratory distress, infections, neurological impact) have a significantly higher risk of mortality throughout childhood & adolescence. #ChildHealth Image
2/
The risk is highest in the first year but persists later in life. Children with neurological problems appear particularly vulnerable. This underscores the critical need for regular medical follow-ups & comprehensive support for these families. #PediatricCare #PublicHealth Image

Separately, new findings highlight another crucial aspect of maternal & infant health: COVID-19 infection during pregnancy can elevate the risk of preterm birth. Preterm birth itself can lead to various health challenges for the newborn. #PregnancyCare #COVID19 Image

5½ years since the first COVID-19 case in Sweden, and the long-term battle continues. Meet Victoria, 21, who was once an athlete training 20 hours a week. Now, almost four years after her infection, she lives with debilitating daily headaches due to #LongCOVID. #Sweden Image
2/Victoria's story is heartbreakingly common. "I don't know what it feels like to have a day without a headache," she says, unable to do the things she loves. She also shares the immense challenge of getting her symptoms recognized and received #InvisibleIllness #HealthcareCrisis Image

adequate care from the healthcare system.
The scale of this crisis is staggering. At least 300'000 Swedes live with severe, long-term symptoms after a COVID-19 infection. Crucially, the Swedish COVID Association estimates

We spend fortunes ensuring our drinking water is pristine – consuming maybe 2-3 liters daily. And rightly so! But what about the 11,000 liters of air we breathe every single day? #CleanAirNow #PublicHealth Image
2/
Think about it: We wouldn't tolerate dirty tap water. Yet, we often overlook the unseen quality of the air in our public spaces. This oversight has real health and economic consequences. #AirQuality #InvisibleThreat Image
3/
Investing in clean indoor air isn't a luxury; it's a fundamental public health necessity. From schools to workplaces, better ventilation & filtration protect us all from airborne pathogens & pollutants. #HealthyBuildings #IndoorAirQuality Image
