Has anyone's child caught herpes or other viral illness from nursery?

[Peridotty]

I was wondering what the chances are of my baby catching a disease at nursery. I am scared she might catch the coronavirus, hand foot and mouth disease, herpes, etc from other children. I know that at that age the babies are putting things in their mouths so it's an easy way to transmit disease. Do the teachers allow sick children to go into school? Do they clean the toys after the baby's put it into their mouths?
I know that herpes is pretty common and 50-60% of people have it, but I don't have it and neither does my husband and we would prefer that she doesn't get it either.
Has anyone's baby/child caught something from other kids at nursery? Or is it pretty rare for babies and toddlers to have those kinds of diseases?
Should I wait until she is past the age where kids put things into their mouths before contemplating nursery? The alternative is a nanny.
Thanks.

My DC is 2.5 and has been in nursery since she was 9mo. She was ill about once a month from about 9-18m tbh and she had HFM three times within about 4 months at one point. Also had roseola once. The rest were mainly viral cold infections and a couple of DnV bouts, oh and she had conjunctivitis a couple of times too. I can't track every single infection to nursery as we were active at things outside of nursery too, but I imagine the majority did come from nursery.

As she's gotten colder, and with covid meaning there have been less kids in nursery/nursery more strict about unwell children not attending/stricter cleaning protocols etc she is becoming ill much less often and much less severely too.

As an aside, me and DH both have HSV1, DH's is symptomatic a lot (once a month?) and DD hasn't had a coldsore before.
