I understand about infections and WBC being low from being in certain environments, pets, children, etc. But, a relative told my sister who had chemotherapy after a mastectomy over 6 months ago that she cannot be around her for more than a day. She did not explain why, nor did she say what her illness is which we suspect has something to do with her telling her that in a letter.
What other illnesses would affect her unless she is on chemotherapy herself and is concerned about infections, etc.?
