A man aged 28 years was admitted to hospital with fever and headache in April, 2020. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) PCR testing from an oropharyngeal swab was negative, and he was discharged from hospital and sent home the next day. 8 days later, he presented again with dry cough and severe respiratory distress. Oxygen saturation was 72% with 15 L/min of oxygen via a non-rebreather mask. He was immediately intubated ...

Despite the direct neuronal path between the nose and the brain's olfactory bulb, airborne diseases rarely cause fatal encephalitis. Findings from a study in mice suggest that viruses can reach the olfactory bulb but a frontline immune reaction prevents any damage or further spread. Using a fluorescent vesicular stomatitis virus, researchers showed how scavenger immune cells in the brain called microglia acquire viral material from neurons and pr...

Background: To accurately interpret COVID-19 seroprevalence surveys, knowledge of serum-IgG responses to SARS-CoV-2 with a better understanding of patients who do not seroconvert, is imperative. This study aimed to describe serum-IgG responses to SARS-CoV-2 in a cohort of patients with both severe and mild COVID-19, including extended studies of patients who remained seronegative more than 90 days post symptom onset. Results: Forty-seven patient...

Background. Currently it is unknown whether a positive serology results correlates with protective immunity against SARS-CoV-2. There are also concerns regarding the low positive predictive value of SARS-CoV-2 serology tests, especially when testing populations with low disease prevalence. Methods. A neutralization assay was validated in a set of PCR confirmed positive specimens and in a negative cohort. 9,530 specimens were screened using the D...

Objectives: Determine indications and clinical utility of SARS-CoV-2 serology testing in adults and children. Design: Prospective evaluation of initial three weeks of a daily Monday to Friday pilot SARS-CoV-2 serology service for patients. Setting: Early post 'first-wave' SARS-CoV-2 transmission period at single centre London teaching hospital that provides care to the local community, as well as regional and national referral pathways for speci...
