Covid-19 may cause the brain to age by 10 years

Only 12% of the study's participants who tested positive for Covid-19 antibodies already knew that they'd had the illness.

King Soopers' parent company, will be the first US retailer to sell rapid antibody testing. Staff who had direct contact with Covid-19 patients showed a positivity rate of 20%.

The question of whether or not having COVID will protect you from getting it in the future, similar to chickenpox, is ongoing.

If a person tests positive for antibodies, it means they were once infected.

I am not a scientist and id like to keep it that way because this medical jargon is a doozy to de-code.

The FDA-authorized rapid antibody tests - conducted using a finger-prick blood sample -are now available at Kroger pharmacies in California (Ralphs) and MI, and will be available at all Kroger pharmacies and clinics by the end of November.

The study highlights that, although all ages are affected by this reduction, the elderly accuse it more: between June and September, the percentage of people over 75 with antibodies fell by 39%, while the reduction was 14, 9% in the age group between 18 and 24 years.

Asked about herd immunity, Helen Ward, professor of public health at Imperial College London, said: "Even at best, (in the first round of the study) 94% of the population remained not likely protected, and now that has declined to over 95% of the population who don't have evidence of antibodies".

Eleanor Riley, professor of immunology and infectious disease at the University of Edinburgh, said the study suggested that home antibody testing kits were not useful for people trying to assess their own previous exposure.

The study was published online in the journal Brain, Behavior and Immunity.

The researchers found that COVID-19-associated strokes often followed a characteristic pattern, with stroke caused by blockage of a large cerebral artery, and brain imaging showing strokes in more than one cerebral arterial territory.

"Indeed, decreasing levels of antibodies is not ideal - with waning protection from natural infection also suggesting that vaccines against this pathogen might not confer long-lasting protection and require seasonal vaccination for control - our understanding of the natural course of this disease is still nascent".

According to the researchers, the virus may not be directly causing the brain damage, but alterations in oxygen intake, heart problems related to COVID-19, or other side effects may be involved.

REACT has been commissioned by the Department of Health and Social Care, and is being carried out in partnership with Imperial College London, Imperial College Healthcare NHS Trust and Ipsos MORI.

Another separate arm of the REACT study is now monitoring levels of current infection in the United Kingdom using at-home swab tests, involving over 150,000 people every month. Declining prevalence of antibody positivity to SARS-CoV-2: a community study of 365,000 adults MEDRXIV-2020-219725v1-Elliott.pdf. An earlier cross-sectional study conducted by Finzi et al found that the ability of plasma to neutralize the virus decreased between 3 and 6 weeks after symptom onset.
