Are Squamous Cells HPV?

I had my first PAP smear done in Dec and I got a call today saying they found squamous cells but they said it’s nothing I need to worry about and they usually clear up on their own I just need to have a PAP smear done every year instead of every three years. I asked the nurse if that’s a sign of cancer and she said no but she did mention something about HPV… I was wondering if anyone could explain the correlation to me… I’m confused because I thought HPV was an STD but the nurse told me not to worry about it and didn’t say I needed to inform my sexual partner…

I’m so confused are squamous cells indicative of HPV?
