viral persistence

Abstract Introduction: The relationship between SARS-CoV-2 viral dynamics during acute infection and the development of long COVID is largely unknown. Methods: A total of 7361 asymptomatic community-dwelling people enrolled in the Test Us at Home parent study between October 2021 and February...

Hi I wanted to create a thread on the organisation long covid action project to keep up with what they are doing. (A lot of which worries me.) This organisation says and claims as fact that long covid is a single disease caused by viral persistance. From their front page: Long Covid is a...

The neurobiology of SARS-CoV-2 infection Meinhardt, Jenny; Streit, Simon; Dittmayer, Carsten; Manitius, Regina v.; Radbruch, Helena; Heppner, Frank L. Worldwide, over 694 million people have been infected with SARS-CoV-2, with an estimated 55–60% of those infected developing COVID-19. Since the...

SARS-CoV-2 viral persistence in lung alveolar macrophages is controlled by IFN-γ and NK cells Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA generally becomes undetectable in upper airways after a few days or weeks postinfection. Here we used a model of viral...

SARS-CoV-2 infection triggers pro-atherogenic inflammatory responses in human coronary vessels Abstract Patients with coronavirus disease 2019 (COVID-19) present increased risk for ischemic cardiovascular complications up to 1 year after infection. Although the systemic inflammatory response to...

Tonsils are major sites of persistence of SARS-CoV-2 in children ABSTRACT In the present study, we show that SARS-CoV-2 can infect palatine tonsils, adenoids, and secretions in children without symptoms of COVID-19, with no history of recent upper airway infection. We studied 48 children...

Abstract Two coronaviruses were isolated from brain material obtained at autopsy from two multiple sclerosis patients. The viruses were neutralized by serum and spinal fluid from these patients. Although most of the population have antibody to these virus isolates, multiple sclerosis patients...

SARS-CoV-2 reservoir in post-acute sequelae of COVID-19 (PASC) Abstract Millions of people are suffering from Long COVID or post-acute sequelae of COVID-19 (PASC). Several biological factors have emerged as potential drivers of PASC pathology. Some individuals with PASC may not fully clear the...
