Biology question about Covid

Module 2: In this module, you will discuss signs & symptoms of mild, moderate, and critical covid-19 patients.  Use of a Table format is encouraged, followed by a discussion on each sign and symptom (at least 6-8 signs and symptoms such as cytokine storm). For example, many patients complain that they lose their olfactory sense or blood coagulation can lead to stroke in some patients or critical Covid patients exhibit what is known as ground-glass opacities in their lungs (you might want to show side by side CT-scan or X-rays images of normal lungs and covid19-infected glass lungs). This module is aimed at understanding the signs and symptoms of the disease in human. You may want to discuss a mysterious phenomenon observed in a small portion of recovered COVID patients known as Long COVID.
