Science Numerous viruses use specialized surface molecules called fusogens to enter host cells. Many of these viruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can infect the brain and are associated with severe neurological symptoms through poorly understood mechanisms. We show that SARS-CoV-2 infection induces fusion between neurons and between neurons and glia […]

Natural history of long-COVID in a nationwide, population cohort study
Nature Previous studies on the natural history of long-COVID have been few and selective. Without comparison groups, disease progression cannot be differentiated from symptoms originating from other causes. The Long-COVID in Scotland Study (Long-CISS) is a Scotland-wide, general population cohort of adults who had laboratory-confirmed SARS-CoV-2 infection matched to PCR-negative adults. Serial, self-completed, online questionnaires […]

The SPIN framework to control and prevent the Marburg virus disease outbreak in Equatorial Guinea
NIH Abstract A full grasp of the epidemiological factors promoting transmission is necessary for responding to highly infectious diseases, which involves their control and prevention. With the recent outbreak of Marburg Virus Disease (MVD) in Equatorial Guinea, we saw the need to re-shed some technical light based on our field experiences and published literature. We […]

BMJ Objective To evaluate longer term symptoms and health outcomes associated with post-covid-19 condition within a cohort of individuals with a SARS-CoV-2 infection. Design Population based, longitudinal cohort. Setting General population of canton of Zurich, Switzerland. Participants 1106 adults with a confirmed SARS-CoV-2 infection who were not vaccinated before infection and 628 adults who did not have an infection. […]

Cross-reactive EBNA1 immunity targets alpha-crystallin B and is associated with multiple sclerosis
Science Multiple sclerosis (MS) is an inflammatory disease of the central nervous system, for which and Epstein-Barr virus (EBV) infection is a likely prerequisite. Due to the homology between Epstein-Barr nuclear antigen 1 (EBNA1) and alpha-crystallin B (CRYAB), we examined antibody reactivity to EBNA1 and CRYAB peptide libraries in 713 persons with MS (pwMS) and […]

The Lancet Self-reported symptom studies rapidly increased understanding of SARS-CoV-2 during the COVID-19 pandemic and enabled monitoring of long-term effects of COVID-19 outside hospital settings. Post-COVID-19 condition presents as heterogeneous profiles, which need characterisation to enable personalised patient care. We aimed to describe post-COVID-19 condition profiles by viral variant and vaccination status. In this prospective […]

Frontiers in Cardiovascular Medicine Coronavirus disease 2019 (COVID-19) is a viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 may have a mild presentation, with few symptoms, or progress to a severe condition, characterized by generalized inflammation, systemic microvascular involvement, coagulopathy, and pulmonary and cardiovascular complications. Men present with more severe symptoms […]

European Respiratory Journal Background COVID-19 is associated with a dysregulated immune response but it is unclear how immune dysfunction contributes to the chronic morbidity persisting in many COVID-19 patients during convalescence (long COVID). Methods We assessed phenotypical and functional changes of monocytes in COVID-19 patients during hospitalization and up to 9 months of convalescence following COVID-19, respiratory syncytial […]

Science Some people infected with SARS-CoV-2, the virus that causes COVID-19, experience a range of symptoms after the resolution of infection, such as neurological issues that include generalized pain, neuropathy, and myalgia. Serafini et al. found that non-infectious viral RNA was detectable in the dorsal root ganglia of hamsters after intranasal infection with SARS-CoV-2. This phenomenon […]

COVID’s future: mini-waves rather than seasonal surges
Nature Whether you call it a surge, a spike, a wave or perhaps just a wavelet, there are signs of a rise in SARS-CoV-2 infections — again. A growing proportion of tests in some countries are coming back positive, and new variants, most notably a lineage called XBB.1.16, are pushing aside older strains, fuelling some […]
