[Myiasis: wound infection caused by fly larvae in a nursing home]

Area of Science:

• Medical Entomology
• Infectious Diseases
• Podiatric Medicine

Background:

• Nursing home residents are susceptible to opportunistic infections.
• Wet gangrene presents a risk for secondary infestations.
• Environmental factors in healthcare settings can influence pathogen and vector entry.

Observation:

• A 66-year-old male nursing home resident presented with wet gangrene of the foot.
• The patient was undergoing conservative treatment during the summer months.
• Larval fly infestation (wound myiasis) was identified within the necrotic wound.

Findings:

• Wound myiasis was diagnosed in the patient with wet gangrene.
• The infestation likely occurred due to flies entering the room through open doors.
• Below-the-knee amputation was necessitated by the myiasis and gangrene.

Implications:

• Highlights the importance of environmental control in preventing vector-borne complications in healthcare facilities.
• Underscores the need for vigilant wound assessment in vulnerable populations.
• Emphasizes prompt and appropriate management of necrotic tissue to prevent myiasis.
