Abstract
- BackgroundNeurological complications due to chikungunya virus (CHIKV) infection have been described in different parts of the world, with children being disproportionately affected. However, the burden of CHIKV-associated neurological disease in Africa is currently unknown.MethodsWe estimated the incidence of CHIKV infection among children hospitalised with neurological disease in coastal Kenya. We used reverse-transcriptase polymerase chain reaction (RT-PCR) to systematically test for CHIKV in cerebrospinal fluid (CSF) samples from children aged FindingsThere were 18,341 paediatric admissions during the 5-year study period, of which 4,332 (24%) had CSF collected. The most common clinical reasons for CSF collection were impaired consciousness, seizures and coma (47%, 22% and 21% of all collections, respectively). After acute investigations done for immediate clinical care, CSF samples were available for 3,980 admissions, of which 367 (9.2%) were CHIKV RT-PCR positive. The annual incidence of CHIKV-associated neurological disease varied between 13 to 58 episodes per 100,000 person-years among all children InterpretationAlthough not previously recognized, CHIKV-associated neurological disease is common in coastal Kenya and a significant public health burden.
