I am not sure about dry throat, but some complain of sore throat. Keep in mind though you may not have all or any of the common symptoms even if you have been exposed to it.
I thought I've had it twice since the pandemic, thankfully haven't been exposed to it yet, but my symptoms were due to something else. Sometimes just being paranoid can bring about those symptoms. My sister had it earlier this year. For a little while she was left with side affects from it even though she no longer had covid itself.
I don't like to know the most common symptoms because then I start looking for them and end up finding one or more and I get super paranoid so I don't really even do research on it.. however if I start feeling sick I do go get tested for it.
