My son came down with acaseof the measles a couple years ago. I had heard the measles was going around, so I figured Johnny had it too. He wasn't itching and scratching, he didn't have a fever, didn't have any blotches on his skin, was running around like a kid does, but he definitely had acaseof the measles, so I had him stay home from school for a week till he got over it.
A doctor reports: a patient came in for a regular physical, and in the course of the exam, I determined he had acaseof strep throat. He presented no symptoms, his glands weren't swollen, had no cough or dry throat, had no fever, but a culture of his throat swab, amplified 20 times, convinced me this was definitely acaseof strep throat. I didn't prescribe anything, as there were no symptoms, but I alerted the Health Department of anothercaseof strep throat.
Really, anons, we have to put thiscasememe to bed and bury it. For hundreds of years, when someone had acaseof something, they were sick, had symptoms. Now all of a sudden,casemeans a bug was detected in or on someone's body, and constituted a palpable threat to everyone around him.
