Over the weekend Joanna presented a review poster entitled SARS-CoV-2 on the Clock. The Interplays Between Circadian Rhytmicity and Viral Infections on the Aspects of Neuroscience conference in Warsaw. She explained how circadian clock proteins may vary the susceptibility to SARS-CoV-2 infection throughout the day, and how rhythms in activity of immune cells might become perturbed upon getting infected. She summarised chronobiology-related clinical measures such as timing of the vaccinations, and time-dependent administration of antiviral medications.
