My mom and I had some cold recently, she had to get tested and was tested positive, I didn't need to get tested so I don't know what I had. My dad also got ill and had a raised temperature for a day, but got better soon. Although it doesn't seem like a big deal, like any other cold that lasts it gives a lot of emotions like apathy, irritation, aggression, depression, etc. So having an extra rest seems like a good idea.
