It doesn't have to be a death sentence for one to worry about it. SARS-COV-2 is a novel virus that we are yet to fully understand. There are still a lot of unknowns;
is there a risk of reinfection when someone tests negative?
Can the virus regenerate in the body system?
How does it terminally affect body organs?
Would infection make one more susceptible to future respiratory syndromes?

I would advise anyone regardless of age or health background take the pandemic seriously and reduce the spread.
