Hi Thanks for posting your query on HCM. I appreciate your concern for the old lady bitten by an insect. Apparently she is suffering from maggots infestation caused by a botfly this is referred to as Myiasis. It is an infestation of the skin by developing larvae (maggots) of a variety of fly species the most common being human botfly. She needs to be examined by a doctor for the following possible treatments: Debridement of the wound with irrigation to eliminate the larvae from the wound with application of chloroform, chloroform in light vegetable oil, or ether, with removal of the larvae under local anesthesia, has been found to be effective for wound myiasis. Other treatment option is by occluding or suffocating the larvae by placing petroleum jelly, liquid paraffin, beeswax or heavy oil, or bacon strips over the central punctum and has been used to coax the larvae to emerge spontaneously and they can be caught with forceps. Hope the suggestions given above could be of great help in getting her treated early. Regards. A feed back is appreciated.
