Traumatic Myiasis: A Neglected Disease in a Changing World

Area of Science:

• Parasitology
• Veterinary Medicine
• Medical Entomology

Background:

• Traumatic myiasis involves fly larvae infesting wounds in vertebrates, posing health risks to humans and economic/welfare issues in animals.
• Despite underreporting, especially in tropics, myiasis is a significant concern, with global spread exacerbated by climate change and transport.
• The New World screwworm fly's (Cochliomyia hominivorax) introduction to Libya highlights the risks and costs associated with invasive myiasis agents.

Purpose of the Study:

• To explore the evolution and epidemiology of traumatic myiasis using molecular techniques.
• To highlight the underreported incidence in humans and challenges in managing myiasis in domestic animals.
• To discuss the global spread of myiasis agents and their dual role in causing disease and aiding medical treatments.

Main Methods:

• Review of current literature on traumatic myiasis.
• Analysis of molecular studies on myiasis evolution and epidemiology.
• Case study of Cochliomyia hominivorax incursion in Libya.

Main Results:

• Molecular studies offer new insights into myiasis evolution and epidemiology.
• Human incidence is underreported, particularly in tropical/subtropical regions.
• Global spread of myiasis agents is a growing concern, exemplified by Cochliomyia hominivorax.

Conclusions:

• Myiasis presents a significant global health and economic challenge, requiring continuous management and surveillance.
• The potential for invasive species spread necessitates robust biosecurity measures.
• Despite its detrimental effects, insect larvae have beneficial applications in forensic science and medicine (larval therapy).
