Post-viral Immune-Mediated Vasculitis Following Concurrent Dengue and Chikungunya Infection: A Case Report

Cureus. 2025 May 7;17(5):e83677. doi: 10.7759/cureus.83677. eCollection 2025 May.

Abstract

We present a case of a 78-year-old female who developed persistent neurological complications following a concurrent dengue and chikungunya viral infection. The patient experienced progressive weakness and ambulatory difficulties, culminating in left foot drop. This case highlights the potential long-term neurological sequelae of these tropical viral infections and emphasizes the importance of considering a post-viral vasculitis-like presentation in patients with delayed neurological symptoms.
