All of these are symptoms of Dracunculiasis infection except

The correct option is Facial redness.

Dracunculiasis, also commonly known as guinea worm disease, is a parasitic infection caused by the nematode roundworm Dracunculus medinensis. The infection is transmitted when individuals consume water contaminated with water fleas (copepods) hosting the infective larvae.

Let us analyze the systemic and localized symptoms typically associated with this infection to understand why "Facial redness" is the correct exception:
1. Abscess: As the female adult worm matures inside the host, it migrates to the subcutaneous tissues, typically in the lower extremities (legs and feet). To emerge from the host, the worm secretes a chemical irritant that causes a painful blister to form. If this blister becomes ruptured or contaminated, secondary bacterial infections can readily lead to the formation of localized abscesses.
2. Septic arthritis: If the guinea worm fails to emerge properly or dies within tissue adjacent to a joint, it can provoke severe inflammatory reactions. Additionally, secondary bacterial contamination entering through the ulcer site can spread to nearby joints, resulting in debilitating septic arthritis.
3. Tetanus: Because the emerging worm creates an open skin ulcer (often exposed to dirt and contaminated water during relief-seeking behaviors like bathing the wound in water), it presents a prime entry point for Clostridium tetani spores. Consequently, tetanus is a well-documented and life-threatening complication of untreated guinea worm ulcers.
4. Facial redness: Unlike the symptoms above, localized facial redness (or facial erythema) is not a characteristic, diagnostic, or common symptom of a Dracunculiasis infection, which primarily affects the lower limbs where the worm emerges.

Therefore, all the listed conditions are potential complications or symptoms of Dracunculiasis infection except Facial redness.
