Fever isn’t a defining symptom of Covid. Initially, it was believed that anyone with an active infection would have a fever. That turned out to be wrong, and it led to a lot of people being denied tests and treatment in the early phase of the pandemic because they had Covid byt (I was one of them). People would go out in public with other symptoms because they assumed the absence of a fever meant it definitely wasn’t Covid. So that might be the change in understanding you’ve heard about.

Fever is still a common symptom of Covid. If you have a fever, cough, shortness of breath, fatigue, loss of smell or taste, and/or gastrointestinal symptoms, you may have Covid and you should act as though you are infectious.

Tests are widely available and inexpensive. It doesn’t hurt to give yourself a test, or see a doctor if you think you might have Covid.

Physical exhaustion is the only thing I feel confident is probably highly common.

There was a clarification that people were still contagious even without a fever and that not everyone who gets covid also has a fever or even any symptoms at all. That would be to address the people who were going to public events because they didn’t have a fever or other symptoms.

Dunno. The answer to your actual question is probably just “get an antigen test” though.

I don’t think I had a fever either time I had COVID (Septembers 2023 and '24), though to be fair I also never took my temp at the time so it could’ve just been low enough to not really notice. The telltale sign for me each time was a sore throat.

I ha no symptoms apart from dizziness and weird throbbing feeling in my skull and neck.

I have these right now.for.the first time in a long time, but so far test is neg.
