Tl;dr
After SARS-COV2 infection, immune cells can't detect other viruses, and their ability to respond to bacteria is also hampered by a defective metabolism and surface receptor dysfunction. In addition, they promote spontaneous clotting that could lead to stroke, thrombosis or heart attack.
@doctor_zapp huh, that explains why my immune system seems to lag a little after covid exposure. it eventually gets back to normal though.
