Seven different 'disease forms' identified in mild COVID-19 Study provides new information for a better understanding of the disease -- and potential biomarkers for vaccine development

2020-11-03

Medical University of Vienna In a study recently published in the journal Allergy, a team of MedUni Vienna scientists led by immunologist Winfried F. Pickl and allergologist Rudolf Valenta (both from the Center for Pathophysiology, Infectiology and Immunology) showed that there are seven "forms of disease" in COVID-19 with mild disease course and that the disease leaves behind significant changes in the immune system, even after 10 weeks. These findings could play a significant role in the treatment of patients and in the development of a potent vaccine.

Focus on COVID-19 deaths in under-65s for better insights into infection rates

Simply comparing the total number of deaths across countries may provide a misleading representation of the underlying level of transmission of SARS-CoV-2, the virus that causes COVID-19, because of large differences in reported COVID-19 death rates in elderly populations in different countries.

A brain chemical called noradrenaline is responsible for our responses to uncertain situations -- helping us to learn quickly and adapt our behaviour, a new study has found.

The COVID-19 pandemic has plunged us all into a state of uncertainty. In a rapidly changing situation where it is hard to know what will happen next, making decisions can be difficult. Researchers at the University of Cambridge and University College London created a simplistic model of this uncertain situation in the lab, to understand how our brain responds. They found that when situations seem stable, we tend to rely on our on previous experiences to help us anticipate what will happen in the future. But when the world is volatile, our brain can let go of these expectations and allow rapid learning. The balance between the two approaches is moderated by the brain chemical noradrenaline. The study is published today in the journal Current Biology.
