What are the methods for preventing and treating snake mold spot disease?

It is mostly seen during the plum rain season, or snakes are prone to this disease in low-humidity environments. Symptoms: some block-shaped or dot-shaped black mold spots appear on the ventral scales of the sick snake. If not treated in time, it will ulcerate and cause death. Treatment method: apply 1%-2% iodine tincture topically to the affected area, wiping it 2 times per day; generally it heals in about 7 days.
