COVID-19 is caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Following infection, detectable IgM and IgG antibodies develop within days to weeks of symptom onset in most infected individuals.1-3Why some patients seem not to develop a humoral immune response,...
leading to more severe infections and deaths even in places with high vaccination coverage. This study aims to assess the spatiotemporal variability of the COVID-19 pandemic and estimate the infection fatality rate (IFR), infection attack rate...
Data on effectiveness and protection duration of Covid-19 vaccines and previous infection against general SARS-CoV-2 infection in general populations are limited. Here we evaluate protection from Covid-19 vaccination (primary series) and previous infection in 21,261 university students undergoing repeat...
仅凭胸部CT很难区分COVID-19肺炎和非COVID-19疾病,临床医生应谨慎评估,利用逆转录聚合酶链反应检测来确认是否存在COVID-19感染。 参考文献 (上下滑动可查看) 1.Liang W, Guan W, Chen R, et al. Cancer patients in SARS-CoV-2 infection: a nationwide analysis in China. Lancet Oncol. 2020;21(3):3...
The protection against emerging SARS-CoV-2 variants by pre-existing antibodies elicited due to the current vaccination or natural infection is a global concern. We aimed to investigate the rate of SARS-CoV-2 infection and its clinical features among infe
It underscore the prevalence of respiratory, cognitive, and fatigue symptoms among affected workers, revealing a notable difference between the two infection duration groups.Internal Medicine Journal
While the study was conducted prior to vaccine roll-out, the potentially short duration of protection following natural infection has implications for nursing homes that are now many months out of initial vaccination efforts. Together with the more transmissible Delta variant, gaps in staff vaccination...
19 infection are still largely underrepresented. In this review, we summarized current knowledge about COVID-19-related kidney manifestations, their pathologic mechanisms as well as various pharmacotherapies used to treat patients with COVID-19. We also shed light on the effect of these medications...
