CDC data show the most common symptoms are cough, fatigue, congestion and a runny nose.

Mickelson might be on to something with his question.
Researchers at Oregon Health & Science University, in findings published online in The Journal of the American Medical Association, have found that breakthrough infections of the delta variant created “a robust immune response.”
Those researchers said the findings indicate that “the immune response is likely to be highly effective against other variants as the SARS-CoV-2 virus continues to mutate.
These findings suggest to the researchers that the omicron variant could create “super immunity” while presenting a far smaller percentage of very sick or dying individuals than seen in the delta or earlier variants. More research needs to be done into how this immunity would occur.
