Since January 2020, Elsevier has established a COVID-19 resource center on Elsevier Connect, providing free information in English and Mandarin about the novel coronavirus. The company has granted permission to make all COVID-19-related research available in PubMed Central and other public repositories, with unrestricted reuse and analysis rights, as long as the resource center remains active. In a separate study, the South Thames Retrieval Service in London observed an unusual cluster of eight children with hyperinflammatory shock during mid-April 2020. These children, most of whom were Afro-Caribbean and male, presented with persistent fever, rash, conjunctivitis, peripheral edema, and gastrointestinal symptoms. They progressed to warm, vasoplegic shock, requiring advanced medical interventions. Despite negative SARS-CoV-2 tests, they exhibited elevated inflammatory markers and some developed coronary aneurysms. The authors suggest that this syndrome, similar to Kawasaki disease shock syndrome, may represent a new phenomenon affecting previously asymptomatic children with SARS-CoV-2 infection. Additionally, a study on asymptomatic healthcare workers at Barts Health NHS Trust in London aimed to understand the determinants of asymptomatic or minimally symptomatic infection. The COVIDsortium bioresource collected data through weekly assessments, including health questionnaires, nasal swabs, and blood samples, to identify protective immunity and risk factors for asymptomatic infection.Since January 2020, Elsevier has established a COVID-19 resource center on Elsevier Connect, providing free information in English and Mandarin about the novel coronavirus.
