In the USA, we have a few organizations that try to keep track of the flu. I think they are mostly private companies pushing drug ads though. Before covid hospitals, and doctors, didn't test for the flu viruses. Maybe in severe cases? I know for certain private practice doctors didn't. All you saw was a chart on the wall differentiating a cold, from the flu. In the USA, the government tries to target the upcoming flu vaccine, but is usually wrong on the strain. Personally, I think Americans have been dying for years of SAR viruses, and the government has been blaming the flu virus? We had a family Thanksgiving in my grandmother's house in '98. My sister brought her two very sick kids to the holliday. By the next morning (12-16 hrs after exposure) we were all sick, with the exception of my brother. 5 people who never felt so sick in their lives. I could't even muster the energy to take my slacks off before dropping into bed. 7 days later my grandmother died. I was always under the impression the incubation period was longer than a half day? Whatever that virus was, I will never forget it for a lot of reasons. And of course, my grandmothers cause of death was "complications of the flu", and probally should have been on a respirator, and not sent home so soon?
