By the next morning, the patient's fever and sore throat had subsided and he was feeling better. Despite the very low, but nevertheless real risk of having 'swine flu', the patient had to make some important difficult decisions regarding his state of health and his work deadlines. His work place was a university campus and as he had no lectures that day, he had no need to be in contact with any students. All scheduled appointments on his calendar for the day were cancelled, but he decided to proceed with a ten-minute scheduled presentation to six of his peers regarding a large research grant proposal. A mask was not worn during the presentation, and he returned home immediately after the event. The patient was alone at home but one of his relatives came to visit him unannounced, accompanied by his wife and a ten year old child from a neighboring town. They stayed at his home for that night, as the distance for return travel was considerable.
