I think that the upcoming Diabetes Technology Society meeting in August will be free.
They are scheduling a summit specifically to talk about Covid.
VIRTUAL INTERNATIONAL COVID-19 AND DIABETES SUMMIT
The evidence from China, Europe, and the United States shows that people with diabetes are at very high risk of serious complications and death from COVID-19. To reduce these risks, it is important for the diabetes community to develop an international consensus to identify strategies to protect diabetes patients. In preparation for a potential second wave, the Virtual International COVID-19 and Diabetes Summit will discuss risk reduction by harnessing the potential of digital health, telemedicine, sensors, and pharmacology. Join Diabetes Technology Society as we feature frontline clinicians, scientists, engineers, and social scientists to address the question: How can we protect patients with diabetes from COVID-19?
