Danemia is an acute infection that is mostly prone to recurrence. The prodromal symptoms include sudden onset of fever, chills, malaise and nausea. Erythema appears a few hours to a day later and is progressively enlarged and well-defined. The affected area has red, swollen skin, high skin temperature, and hard nodules and non-depressed edema. The affected area is painful to the touch, burning, and commonly associated with enlarged lymph nodes or with lymphangitis. Blisters, pustules, or small areas of hemorrhagic necrosis may also occur, most commonly on the lower legs and face. Recurrent episodes of dansitis can cause persistent local lymphedema, with the final result being permanent hypertrophic fibrosis called chronic streptococcal lymphedema. The treatment of dermatophytosis is mostly penicillin-based, with a course of 10-14 days. For those who are allergic to penicillin, quinolones and aminoglycosides antibacterial drugs can be used. High-dose antimicrobial therapy is effective during the active period of lymphangitis in patients with recurrent dancunculosis, but requires continued medication for a longer period of time to achieve full effect. Patients because of the long duration of the disease, the use of long-term clinical antibiotics more resistant, recurrent patients its effect is poor.
