Berne in humans, also called furuncular or furunculous myiasis, is an infectious disease caused by the species fly Dermatobium hominis, which has gray color, black bands on the chest and metallic blue belly. The larvae of this fly are able to penetrate the person's skin, even if there are no injuries, and remain in the tissue, leading to the appearance of a pus wound that causes a lot of pain.
These flies are usually found in humid places and with mountains, being uncommon in Northeast Brazil, being important to control them in these places. As soon as any indicative sign of berne appears, it is important that the larva is removed as soon as possible, otherwise it may favor the occurrence of more infections, complicating the person's health status. Here are some natural ways to get the fly off its skin.

Main signs and symptoms
After the eggs are deposited by the female fly, the larvae leave the eggs after about 6 days and are able to quickly penetrate the skin, even if it is intact, leading to the appearance of some signs and symptoms, the main ones being:
- Formation of skin wounds, with redness and slight swelling at the site;
- Release of a yellowish or bloody liquid from skin wounds;
- Sensation of something moving under the skin;
- Pain and severe itching at the wound site.
The diagnosis of berne in humans is made by the dermatologist or infectious disease by observing the signs and symptoms presented by the person.
How to treat berne
It is important before removing the larva that it is killed, otherwise the thorns found in its body may remain attached to the skin, which prevents its removal. One of the strategies to kill and remove the larva is by means of asphyxiation, where you must put a plaster on the place where the larva is and leave for about 1 hour. Then, remove the tape and check that the larva is glued, otherwise apply small pressure on the site so that the larva leaves. It is important that afterwards the region is treated with antibiotic ointments, which should be recommended by the doctor, to avoid the occurrence of infections.
The use of tweezers should only be done when even with slight compression the larva does not come out, it is recommended that this be done by the doctor to avoid infections. In more severe cases, the doctor may recommend performing minor surgery to make a cut on the skin and widen the orifice, allowing the larva to be removed, or the use of antiparasitic remedies to kill the fly larva.
