Bulletin 20 | Joseph Lu
This bulletin explains how COVID-19 kills.
Emerging evidence shows that COVID-19 can damage the lung, leading to low blood-oxygen levels and death. The joint-culprits are the virus and an over-reacting immune system. The virus infects primarily the lung and potentially other organs including the heart and kidney. Our own immune system may over-react, leading to cytokine storm that damages these organs. This damage, combined with oxygen deprivation, kills.
