Rise in babies are being born with heart defects. This isn’t lockdowns, obviously, they didn’t even exist then! It’s obviously not school closures. And it’s obviously not masks. So can we start tackling the root cause now? COVID. #SARSCoV2 #LongCovidKids www.news-medical.net/news….

Pandemic linked to 16% rise in babies born with heart defects

The proportion of babies born with a congenital heart abnormality increased by 16 per cent after the first year of the pandemic, according to research at City St George's, University of London and pub...

Antihistaminika, insbesondere Histaminrezeptor-H1 (HRH1)-Antagonisten, hemmen wirksam die #SARSCoV2-Infektion In dieser Studie wurde „nachgewiesen, dass HRH1 als alternativer Rezeptor für #SARSCoV2 fungiert, indem er direkt an das virale Spike-Protein bindet.🧵 #COVID19 #Corona

Fig 7 Antihistamine drugs prevented SARS-CoV-2 infection in transgenic hACE2 mice. (A) Acrivastine at serially diluted concentrations was premixed with authentic SARS-CoV-2 D614G viruses, followed by incubation with HEK293T-hACE2 cells. After 48 h, the viral RNA in the supernatants was extracted and quantified via RT-PCR-based detection. The IC50 value was calculated based on the relative number of viral RNA copies within each concentration. (B) The IC50 of triprolidine against the authentic SARS-CoV-2 D614G strain was measured and calculated as described in panel A. (C) Schematic of the animal infection assay. Four transgenic hACE2 mice (C57BL/6) were intravenously administrated with acrivastine at a dosage of 10 mg/kg of body weight. Mice in the control group were administrated with an equal volume of saline. Six hours later, all mice were intranasally challenged with 1 × 105 focus-forming units of the SARS-CoV-2 D614G virus. …

The CDC has been updating #SARSCoV2 genomics every 2 weeks but has failed to do so since their 9 May post. covid.cdc.gov/covid-data-t... This isn't a good idea with 2 new variants emerging (NB.1.8.1 in Asia, and XFG in the US). Graph by @jpweiland.bsky.social

I still remember the first time I saw #SARSCoV2 in the brain in the microscope, back in 2021. I was supposed to be looking at brains with Alzheimer, the neuroinflammation is similar. I knew #NeuroCovid was going to be pretty bad. We are just starting to see how much. #LongCovid

From the New York Times: Can’t Think, Can’t Remember: More Americans Say They’re in a Cognitive Fog
Adults in their 20s, 30s and 40s are driving the trend. Researchers point to long Covid as a major cause.
And younger adults are driving the trend.

Wie #COVID19 Ihr Herz angreift: #SARSCoV2 infiziert direkt die Arterien des Herzens Selbst Patienten mit leichten COVID-Symptomen könnten ein höheres Risiko für Herzerkrankungen und Schlaganfälle haben. Die Studie ergab auch, dass das Virus in den Zellen überleben … #Coronavirus

🧵 Our grandmas were onto something when they told us to have some tea when we were sick. Cool paper showing several Omicron-era #SARSCoV2 variants effectively inactivated by green tea, Matcha, & black tea, mediated by EGCG and TFDG: www.nature.com/articles/s41... #MedSky #IDSky #MedEd #COVID19 /1

This is one of the most impressive studies showing the impact of #NeuroCovid. #SARSCoV2 persists in the body for years after infection, especially in the skull and meninges. Vaccines help but cannot stop it. Which organs are affected by SARS-CoV-2 vs. H1N1 influenza? Check below.

Visualization of viral tropism for Influenza virus H1N1 and for SARS-Cov-2 in mice. Spike protein was found near blood vessels in most organs, including the heart, lung, liver, kidney, intestine, thymus, spleen, pancreas, and brain. By contrast, the influenza H1N1 surface protein hemagglutinin (HA) was primarily detected in the liver and lung only.

Our new study shows that SARS-CoV-2 spike protein accumulates & persists in the body for years after infection, especially in the skull-meninges-brain axis, potentially driving long COVID. mRNA vaccines help but cannot stop it🔬🧠🦠🧵Your weekend read👇 @cellpress.bsky.social cell.com/cell-host-mi...

Irland: „Wir ertrinken in einer Welle von #COVID19, aber die Krankenhäuser bestehen nicht einmal auf Masken Jeder ist anfällig für #SARSCoV2, vor allem unsere Vulnerablen. Die Politiker […] gaben uns die Erlaubnis, uns nicht mehr um sie zu kümmern. Wir haben sie ergriffen.
