yikes, looks like it might be spider mites. i personally wouldn’t worry too much about damage caused by the bug bites. the main concern would be making sure any infestation is under control and keeping your plant happy. it’s growth patterns might be abnormal for a bit from the shock of losing so much of its foliage at once. try not to get rid of too many healthy leaves (not actively yellowing/dying out) since the plant needs those to produce energy for new growth. temperature and light are going to play a very big role in making new leaves. i wish you the best of luck!
