Litter box drama

My little terror (child) has some how found her way into where we’ve gated the litter box, leading to barricading and gating off the litter box but still somehow makes it in there within the 30 seconds she’s out of my site. Should I be concerned? I’m terrified of the litter box, immediately wash her hands and mine and clean everything. I’m so nervous I’m going to get the parasite that causes birth defects 😭 is this common? Or tests?
