some lucky people have no symptoms at all
The Covid-19 strain of Coronavirus has taken many forms among the patient population. Some individuals have very severe symptoms, ending up on a ventilator in the ICU with long-lasting effects. Some have a few days of cold-like symptoms, and some lucky people have no symptoms at all! Therefore, we are presented with the very real possibility that many people may have already had the disease and recovered from it. If so, they probably have some immunity built up.
It is easy to see why the public would want to know if they were one of the lucky ones who had already built immunity. As this pandemic wears on, we all crave a return to normalcy – immunity would be great news!
