    In this update, we cover summaries of our two latest videos in the ongoing COVID-19 Pandemic Updates Explained Clearly lecture series. Dr. Seheult reviews recent information on antibodies and immunity, as well as how to discern reliable research from earlier-stage, lower quality studies and information. Check out these videos and more at!


    Antibodies, Immunity, & Prevalence of COVID-19 – New Data from Spain

    In our 93rd COVID-19 video update, Dr. Seheult talks about rising case numbers and daily deaths, as the U.S. reemerges as a global hotspot for the coronavirus. In addition, he talks about antibody response and its importance in terms of immunity (e.g., “immunity passports” which may  enable previously infected people to return to pre-pandemic activities) and the future of this novel coronavirus. To explain, he references this study published in Nature that compares antibodies in 37 confirmed symptomatic and asymptomatic COVID-19 patients. This research found that asymptomatic patients may be less likely to have neutralizing antibodies, highlighting the risk and insufficiency of COVID-19 “immunity passports” and supporting the continuation of social distancing measures. 

    Another seroepidemiological study from Spain looked at a much larger population of patients — nearly 36,000 households. Using two different IgG antibody tests, researchers found that nearly one-third of infections were asymptomatic and a large portion of symptomatic patients remained untested. Thus, this research yields similar support for continued public health and social distancing practices in Spain and elsewhere. 


    COVID-19 Treatment with Inhaled Steroids; New Pneumonia in Kazakhstan?

    In our 94th COVID-19 video update, Dr. Seheult talks about the massive amounts of articles and data available in the research and treatment of COVID-19. In doing so, he reminds us of the importance of how particular studies are designed, and how large randomized controlled trials (RCT) should typically be the  minimum standard for interventions that change public policy or clinical practice. That said, it’s valuable to have awareness of other potentially promising treatments from observational studies — such as inhaled corticosteroids and this review on its current research — because these studies can point the way to the design and approval of large RCTs. Dr. Seheult discusses this information and summaries of additional research on asthma and COVID-19, n-acetylcysteine, as well as information from Kazakhstan regarding controversial news of a “new” type of pneumonia that may be unrecognized COVID-19.
