The severity of<unk>  is subject to great variability from one person to another and in the same person from one<unk> casion to the next. The prognosis of such infection is usually excellent after the application of topical or systemic treatments. However,<unk>  can be recurrent. Individuals continue to be at risk of the condition if underlying factors such as reduced salivary flow rate or immunosuppression are not rectifiable.<unk>  can be a marker for underlying disease, so the overall prognosis may also be dependent upon this. For example, a transient erythematous<unk>  that developed after antibiotic therapy usually resolves after antibiotics are stopped (but not always immediately), and therefore carries an excellent prognosis—but<unk>  may<unk> casionally be a sign of more sinister undiagnosed pathology, such as HIV/AIDS or leukemia. It is possible for<unk>  to spread to/from the mouth, from sites such as the pharynx, esophagus, lungs, liver, anogenital region, skin or the nails. The spread of<unk>  to other sites usually<unk> curs in debilitated individuals. It is also possible that<unk>  is spread by sexual contact. Rarely, a superficial candidal infection such as<unk>  can cause invasive<unk> , and even prove fatal. The observation that Candida species are normally harmless commensals on the one hand, but are also<unk> casionally capable of causing fatal invasive<unk>  has led to the description "Dr Jekyll and Mr Hyde". The role of thrush in the hospital and ventilated patients is not entirely clear, however, there is a theoretical risk of positive interaction of candida with topical bacteria.
