"We document facts about the COVID-19 pandemic worldwide relevant for those studying the impact of non-pharmaceutical interventions (NPIs) on COVID-19 transmission. When interpreted through a range of epidemiological models, Facts 1-3 imply that both the elective reproduction numbers and transmission rates of COVID-19 fell rapidly from widely dispersed initial levels during the 30 days after cumulative deaths reached 25. After this initial period of rapid decline, the elective reproduction number has hovered around one everywhere in the world."
"A growing body of evidence indicates sex differences in the clinical outcomes of coronavirus disease 2019 (COVID-19)1–5. However, whether immune responses against SARS-CoV-2 differ between sexes, and whether such differences explain male susceptibility to COVID-19, is currently unknown. In this study, we examined sex differences in viral loads, SARS-CoV-2-specific antibody titers, plasma cytokines, as well as blood cell phenotyping in COVID-19 patients.”
