On July 7, Dr. Ta Quoc Hung, Department of Dermatology - Cosmetic Dermatology, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, said that the patient had severe contact dermatitis due to the toxin of the three-cavity ant. The patient said that this was the fourth time he had been stung by the three-cavity ant, and also the most severe time, with burns all over his body.
The doctor cleaned the wound, treated the infection, and restored the skin. The patient avoided scratching, scratching, or applying strong pressure to the damaged skin area to avoid infection. After nearly a week of treatment, the wound was less swollen and gradually healed.
The three-cavity ant mainly lives in humid environments, thrives in the rainy season and prefers night lights such as rice fields, gardens, landfills, and construction sites. The toxin of the three-cavity ant is very strong, 12-15 times stronger than that of cobra venom, but the amount of contact is small and only on the skin, so it is not enough to kill people like snake venom.
Doctors recommend distinguishing between skin inflammation caused by ants and herpes zoster, and not treating it at home. Lesions caused by ants are red, patchy, streaky, with a slightly raised base, with tiny blisters or pustules in the middle, and a slightly sunken area that is yellow-brown, round or oval. Initial signs are itching, burning, and sometimes pain. The progression of the infection lasts from one to three weeks, depending on the amount of toxins on the skin.
People with shingles often have a low fever of about 38 degrees, headache, fatigue, back pain, and pain along the nerves in the skin area where the lesions are about to appear. Then, blisters appear on the skin, often linked together (clustered), the older the age, the more painful it is.
To avoid insect bites, you should clean the environment, clear bushes and grass, shake towels and clothes before using. When working in the fields, especially during the rainy season, you need protective gear such as long-sleeved clothes, hats, masks, and boots.
If you encounter a red-banded ant, do not rub it, but wrap it in paper and throw it away. Skin areas that come into contact with the ant should be washed immediately with soap and water. Clothes, masks, and bed sheets that come into contact with the red-banded ant should be washed thoroughly. Windows and doors in offices and bedrooms should be closed at night.
