If it gets bad ->
It is not only the previous drugs (that you took to help cure you when you were infected the first time) that kill you when or if you are reinfected, its the weakened heart from the first infection. A symptom of this virus is a beating heart rate at a very rapid pace for many days. This damages the heart. This is why a US doctor working with a coronavirus patient, administered medication to help the heart (slow it down) though it in theory this prolonged the recovery period. Better to be sick longer than get well quicker and destroy your heart in the process. This second infection, if common, means a much higher fatality rate.
