Researchers from Helmholtz Munich and Ludwig-Maximilians-Universität (LMU) have identified a mechanism that may explain the neurological symptoms of Long COVID. The study shows that the SARS-CoV-2 spike protein remains in the brain’s protective layers, the meninges, and the skull’s bone marrow for up to four years after infection. This persistent presence of the spike protein could trigger chronic inflammation in affected individuals and increase the risk of neurodegenerative diseases. The team, led by Prof. Ali Ertürk, Director at the Institute for Intelligent Biotechnologies at Helmholtz Munich, also found that mRNA COVID-19 vaccines significantly reduce the accumulation of the spike protein in the brain. However, the persistence of spike protein after infection in the skull and meninges offers a target for new therapeutic strategies.

Cognitive behavioural therapy (CBT) and a programme of physical and mental rehabilitation probably improve symptoms of long covid, but the effects are modest, finds a review of the latest evidence published by The BMJ today.

In this study, stopping universal masking and SARS-CoV-2 testing was associated with a significant increase in hospital-onset respiratory viral infections relative to community infections. Restarting the masking of health care workers was associated with a significant decrease.

Announcing a new article publication for Zoonoses journal. Zoonotic transmission of severe acute respiratory coronavirus 2 (SARS-CoV-2) has been found to result in infections in more than 30 mammalian species.

Exposure to air pollutants (PM_2.5 and PM₁₀) is associated with an increased risk of persistent long-COVID symptoms, partly due to its impact on the severity of the acute infection. This is the main conclusion of a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by “la Caixa” Foundation, in collaboration with the Germans Trias i Pujol Research Institute (IGTP), and published in Environmental Health Perspectives. 

Despite a heavy infusion of public and private support during the COVID-19 pandemic, Medicaid and Medicare beneficiaries in Oregon reported that housing and food insecurity shot up during the onset of the pandemic in March of 2020 — and their basic needs remained in doubt through at least the end of the following year. The survey data were reported in a study led by Oregon Health & Science University and published today in the Annals of Family Medicine.

About The Study: No unexpected reactions were identified in this analysis of reactions to COVID-19 vaccines among children. Similar to this study, data from clinical trials and V-safe found that irritability was the most common systemic reaction among children ages 6 months to younger than 2 years, followed by fever and fatigue or sleepiness. In contrast to other studies observing a higher prevalence of reactions after the second COVID-19 vaccine dose, this study observed a higher prevalence after the first dose. This difference may reflect maternal vaccination; the first COVID-19 vaccination in this cohort may be some children’s second immunological encounter with a COVID-19 vaccine.
