Dr. Christina Mack, an epidemiologist with IQVIA Real World Solutions, talks with Dr. Josh Sharfstein about how the team continues to monitor the health and safety of players and staff, and some of the findings with real-world implications such as how long people can shed COVID-19 virus, if people with asymptomatic infections are less likely to transmit COVID, and whether boosters really work.

But much less is known about Type 1, long mislabeled “childhood diabetes.” Johns Hopkins epidemiologists Elizabeth Selvin and Michael Fang talk with Stephanie Desmon about new research debunking a lot of previously held assumptions about Type 1 diabetes, the prevalence of adult onset and correlation with obesity, and why different approaches to diagnosis and management are necessary. They also discuss the cost of insulin and why more research is needed around medications like Ozempic for Type 1 diabetes.
