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

## TL;DR

An elderly woman developed long-term neurological issues after being infected with both dengue and chikungunya viruses, suggesting a possible post-viral immune response.

## Contribution

This case report introduces a rare post-viral immune-mediated vasculitis following concurrent dengue and chikungunya infection.

## Key findings

- The patient developed progressive neurological symptoms, including left foot drop, after concurrent dengue and chikungunya infection.
- The case suggests a possible immune-mediated vasculitis as a delayed complication of these viral infections.
- It underscores the need to consider post-viral vasculitis in patients with delayed neurological symptoms after tropical viral infections.

## 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.
