1969, 110 fever, emergency room trips, almost died. Haven’t been sick since!!!
I also had that flu. I was a senior in high school and attended a Saturday evening event at the school. Later into the evening I felt like I was hit with a 2 x 4. I remained sick in my bed through the following Friday. There were sky high temperatures, sweats, vomiting and even hallucinations. Finally after 5 plus days it broke. I don’t recall if anyone else in my family got this. Like others here I really haven’t been sick since.
