The association of dengue infection (DI) with atypical neurological manifestations was first reported in 1976. DENV-2 and DENV-3 serotypes are mostly related to neurological problems. DI has shown an overall risk of 21 autoimmune diseases, and 4% may develop neuromuscular complications. The pathogenetic mechanisms behind myasthenia gravis (MG) occurring during DI is thought to be linked to the neurotrophic effect of the infection. We report a unique case of DENV-1 infection presenting with bilateral ptosis and dysphagia in a previously healthy adult.
