So far, we have not yet identified the exact type of insect that causes this disease. Some authors believe that the cause of insect contact dermatitis (VDTXDCT) can be caused by ant colonies (ants, ants, ants, paired ants . depending on the locality) with scientific names. Paedérus - is an insect belonging to the Staphylinidae family, which has nearly 20,000 different varieties but is often found in P. Literlis, P. Fiscipes, P. Caligatus . This is an insect of tropical, hot and humid.
Insects often hide in the fields, under piles of excess materials or waste dumps . when flooded water no longer has a residence, they fly into the house under lights and contact with objects. Indoor use such as towels, washcloths, bedding for blankets, clothes . causes illness for VDTXDCT for users of such items.
Therefore, the disease usually occurs in the rainy season, especially after heavy rains. The patient suddenly felt burning in the skin in the morning after waking up (over 60%), over 70% of patients working under lights like at work, school . Common burns in place Open skin, such as the face, neck, arms, and legs, can also be scattered throughout the body or in folds.
