How to distinguish - COVID-19 symptoms from a cold?

[AriaH]

Is this a new - COVID-19 symptoms or just a cold? || I started feeling really tired with a scratchy throat two days ago, but no fever. Now I have this weird pressure in my ears and a slight cough. It feels different from my usual colds. I took a home test and it was negative, but I've heard the new variants can be tricky to catch on those. I'm just not sure if I should isolate or what.

Is this vaccine information, testing guidelines, long COVID symptoms? || I woke up with fatigue, a scratchy throat, ear pressure, and a light cough that started two days ago. No fever yet, a home test came back negative, but I know those can miss early infections. I’m wondering if I should isolate or just ride it out, especially with concerns about new variants. I’m trying to figure out vaccine information, testing guidelines, long COVID symptoms to decide what to do next. Appreciate any guidance.
