hospice foster kitten had panleuk now i’m freaking out.

i took home a very malnourished sick kitten yesterday. he had an awful URI that was improving but wouldn’t eat or gain weight. he stayed in his crate or in my lap all night. he had to be euthanized this morning, and we tested a stool sample after to which we found out he had panleuk. i’m freaking out. he was in my bedroom and in my lap. i didn’t let him interact with my adult cats but they went in my room this morning after i had taken him back to the shelter. they’re both vaccinated but the risk is eating me alive right now. i don’t even know why im posting this i don’t know if anyone has advice or reassurance or anything but oh my god
