If through the history, clinical manifestations, patch test, etc. clearly diagnosed herpes sweat is not need to carry out fungal examination; however, due to herpes sweat clinical manifestations and fungal infection caused by tinea pedis is extremely similar, so in the case of can not be clearly diagnosed, need to carry out fungal examination.

Experienced physicians can accurately diagnose herpes sweat blisters through history, clinical presentation, and patch test, at which point a fungal test is no longer necessary. However, as mentioned earlier, the clinical manifestations of the two diseases are extremely similar, and sometimes even experienced doctors are unable to make a completely clear diagnosis, at which time a fungal examination is required. It is recommended that patients with blisters and flakes on hands and feet go to regular hospitals in a timely manner, and under the guidance of the doctor to carry out the relevant examinations and standardized treatment after a clear diagnosis.
