COVID-19 Causes Ciliary Dysfunction as Demonstrated by Human Intranasal Micro-Optical Coherence Tomography Imaging
COVID-19 Causes Ciliary Dysfunction as Demonstrated by Human Intranasal Micro-Optical Coherence Tomography Imaging

COVID increases the risk of secondary infections by impairing mucosal clearance.

"Our results demonstrate profound ciliary loss in the nasal epithelium even in subjects with mild disease and shed light on mechanisms that... probably predispose patients to secondary infections."

Obeldesivir for COVID-19 Is Safe, Reduces Time to Symptom Relief in High-Risk Patients
Obeldesivir for COVID-19 Is Safe, Reduces Time to Symptom Relief in High-Risk Patients

My note: Would like to see study on this drug with endpoints like time to recovery, severity of symptoms, long-term follow-up for post-acute symptoms. Not holding my breath. This is, after all, Giliad, the maker of remdesivir. Still, potential early treatment option here:

465 adults received either obeldesivir or a placebo for 5 days. The results showed that those on obeldesivir had a 0% hospitalization rate and lower mortality compared to 0.5% in the placebo group.

Patients taking obeldesivir also experienced quicker symptom relief and greater reductions in the virus levels. Overall, the drug was found to be generally safe and well-tolerated.

‘Don’t worry, send us a head shot and we’ll digitally include it.’

They are literally swapping heads to try to get out of reality.”

Opinion: It's time to clean the germs out of our indoor air
“Over four years later, things are changing. The WHO now finally and fully recognizes COVID-19 is airborne at the institutional level, and has made one of the world’s top aerosol scientists co-chair of their new indoor air advisory group. The WHO also collaborated with particle physicists to develop ARIA, the Airborne Risk Indoor Assessment tool, which models risk of infection for different types of buildings and settings to help us understand how to make indoor air clean.”

A Plea to Maskless Healthcare Workers from Vulnerable Patients

“A Plea to Maskless Healthcare Workers from Vulnerable Patients If you see a mask - wear a mask. Better yet - wear a mask all the time and show us you understand that we're still IN a pandemic. We are depending on you to keep us safe - please don't betray that.”

IMO, the main reason is the cognitive dysfunction caused by SARS-CoV-2.

New Covid XEC symptom 'severely impacts daily functioning' warns doctor

“The most serious symptom is the potential for sudden, acute respiratory failure in individuals who may have previously only experienced mild to moderate symptoms.. Someone can appear to be recovering and suddenly face a rapid decline, often due to microvascular complications in the lungs, leading to severe oxygen deprivation.."

Why Covid waves are still happening throughout the year
Why Covid waves are still happening throughout the year

“Every one of these subvariants is distinct enough that a whole swathe of people are no longer immune to it and it can infect them. That’s why you see this constant undulatory pattern which doesn’t look seasonal at all,” he says. Adding in seasonal factors, such as cooler weather forcing people indoors and children returning to school, and the conditions are frequently conducive to a new wave.”

SARS-CoV-2 can cause lasting damage to cells’ energy production

“SARS-CoV-2, the virus that causes COVID-19, can cause lasting damage to energy production by mitochondria in many organs of the body. Stopping the virus from hijacking mitochondrial energy production may be a novel way to prevent serious complications from SARS-CoV-2 infection.”

“After a year of the pandemic in Arkhangelsk, 59.7% 95% confidence intervals (CI) (56.7; 62.6) of the surveyed population had had COVID-19. Among those who had been infected, symptomatic cases comprised 47.1% 95% CI (43.2; 51.0), with 8.6% 95% CI (6.6; 11.1) of them having been hospitalized. Of the asymptomatic cases, 96.2% were not captured by the healthcare system. Older age was positively associated, while smoking showed a negative association with symptomatic COVID-19. Individuals older than 65 years, and those with poor self-rated health were more likely to be hospitalized. Conclusion More than half of the infected individuals were not captured by the healthcare-based registry, mainly those with asymptomatic infections.”
