It sounds like you’re describing a botfly (Dermatobia hominis) infestation in a human host—something that can indeed happen to people working or traveling in parts of Central and South America.
Here’s some clear, detailed information about this scenario:
About Human Botfly (Dermatobia hominis) Larvae:
- The human botfly lays its eggs on a vector (usually a mosquito or other biting fly).
- When the mosquito bites a human, the warmth causes the eggs to hatch, and the larvae enter the skin.
- The larvae develop in subcutaneous tissue, forming boils or warble-like swellings.
Clinical Presentation:
- Painful, raised nodules with a central punctum (small opening for the larva to breathe).
- Serous (clear) or sometimes bloody discharge.
- Sensation of movement inside the lesion.
Removal Procedure:
- Occlusive method: Covering the breathing hole with petroleum jelly, nail polish, or bacon fat to asphyxiate the larva, causing it to emerge for air.
- Mechanical extraction: Using forceps to pull the larva out through the breathing hole (care is needed to avoid rupture, which can cause inflammation or secondary infection).
- Surgical removal: A small incision under local anesthesia for complete extraction, especially for larger or stubborn larvae.
Aftercare:
- Thorough cleaning of the wound.
- Antibiotic ointment to prevent secondary infection.
- Tetanus vaccination status should be up to date.
Real-World Context for Ecologists or Fieldworkers:
- Working in humid, forested regions in Central/South America is a known risk.
- Prevention includes insect repellents, protective clothing, and avoiding mosquito bites.
If you’re describing or seeking to script or narrate a video of such a removal (as your phrase suggests), a possible clinical-style caption might be:
