It really depends. My grandfather just passed from it. He was in his ninetys but healthy. He was in a rehab home recovering from an injury and was getting ready to be released. They had an outbreak and tested everybody. He developed mild symptoms a few days after testing positive, but it was clearing. We actually thought he was going to beat it. Then he took a turn for the worse with fluid around (not in) his lung. No heart attack, no stroke, his body just wasnt strong enough to fight off the symptoms. I also think there were some small mistakes in his care due to the home being overwhelmed with cases in both patients and staff. Such as when he should have been placed in the critical care ward. That actually came from his nurse but at his age it may not have mattered.
