Myiasis is a medical condition in which fly larvae, commonly called maggots or worms, infest human or animal tissue. It most often affects open wounds, damaged skin, or areas that are not kept clean. Although it may sound rare, myiasis still occurs in many parts of the world, especially in warm and humid climates.
Causes
Myiasis happens when certain species of flies lay their eggs on:
-
Open or untreated wounds
-
Moist skin
-
Soiled bandages or clothing
When the eggs hatch, the larvae survive by feeding on tissue or fluids in the wound. Poor hygiene, lack of proper wound care, and limited access to medical treatment increase the risk.
Types of Myiasis
-
Wound (traumatic) myiasis – larvae grow in open injuries
-
Cutaneous myiasis – larvae infest unbroken skin
-
Cavitary myiasis – affects body openings such as the nose or ears
Wound myiasis is the most common type.
Symptoms
Signs of myiasis may include:
-
Slow or non-healing wounds
-
Increased pain or swelling
-
Redness and inflammation
-
Foul-smelling discharge
-
Visible movement in the wound
-
Fever in severe cases
Health Risks
If left untreated, myiasis can cause:
-
Secondary bacterial infections
-
Tissue damage
-
Serious illness
However, with proper medical care, most cases can be treated effectively.
Treatment
Treatment should always be done by a healthcare professional and may include:
-
Careful removal of larvae
-
Cleaning and disinfecting the wound
-
Antibiotics if infection is present
-
Proper wound dressing and follow-up care
Self-treatment or home remedies are not recommended.
Prevention
Myiasis can usually be prevented by:
-
Cleaning all cuts and wounds immediately
-
Keeping wounds covered with clean bandages
-
Changing dressings regularly
-
Maintaining good personal hygiene
-
Protecting wounds from flies
Conclusion
Worms in wounds, or myiasis, is a preventable and treatable condition. Early medical attention and proper wound care are essential to avoid complications. Awareness and hygiene play a key role in reducing the risk.
