It's like a worse version of the flu. The way that you'll die from the flu is getting a secondary pneumonia infection from Staph aureus or Steptococcus pneumonia, the virus just makes you more susceptible and weaker.

The major lethal consequence for this virus in the Coronavirus family is Acute Respiratory Distress Syndrome (ARDS). A strong outcome for this is we knock you out, put a tube down your throat, and have you breath via mechanical ventilator. It's intense to say the least.
