Short report: Case reports of neuro-chikungunya in Southern Thailand

Abstract

There has been a recent increase in reports of neurologic complications as major causes of morbidity and mortality in chikungunya virus infection. As a part of 2004-2009 global outbreaks, an unprecedented large chikungunya epidemic occurred in Southern Thailand during 2008-2009 in which 49,069 cases were reported. During this period, we encountered two patients with meningoencephalitis and another patient with myeloneuropathy among 1,018 cases diagnosed as chikungunya in our hospital. The clinical pictures are presented and the key points are used to recognize and differentiate chikungunya from Japanese encephalitis virus, dengue virus, and herpesvirus infections, which are more common causes of meningoencephalitis and myelitis in this region.
