I had a coworker of mine get exposed via the spouse of his wife's ex, who they share custody with. He was pretty sure he had a mild case, starting last Wednesday with fevers and not much else. It quickly progressed to him having horrible aches, sore throat and spitting up blood. His breathing became strained that night, and he was on the verge of going in to the hospital. They turned him away on the phone because he was still able to breath without assistance. Luckily, as of this morning he's turned the corner, but as a healthy guy in his early 40's he has said he has never been so scared in his life, and was convinced his life was in danger at the worst stages.
