Can old PDO threads get infected?

Can you get an infection in PDO threads 2 years after having them put in or are they fully dissolved? I had Covid in December which obviously left my immune system compromised, and straight afterwards my face, chin, throat, ears etc (and afterwards further down my body too) broke out in acne and bumps filled with liquid. I think it’s a combination of hormonal acne and perhaps an infection from the threads - the sores/cysts seem to be concentrated at the entry points of the threads
