Molluscum contagiosum is a viral skin disorder. It spreads mostly among humans by close skin-to-skin contact or through common shared bedsheets, towels, handkerchieves, etc. If your mother and your daughter don t share such articles of clothing, there is no need to wash the sheets every day. Secondly, although shingles and molluscum are both caused by the same general kind of viruses, they cannot influence the course of each other s illnesses in any way. Hence, the shingles in your mother has not caused the illness in your daughter. Finally, having a lot of medical problems and being actually immunocompromised are two different things; only a documented case of immunodeficiency with low CD4 (a type of white cells in the blood) counts are vulnerable to catching the infection from another patient. Not an immunocompetent person. Hope this helps.
