Background: Recently Chikungunya virus (CHIKV) outbreaks have been reported in the Carribean. There is no data regarding the outbreak in Curacao. In addition, to date there is no biomarker that could be used to predict chronic infection.Objectives: To characterize the first CHIKV outbreak in Curacao and to identify potential biomarkers for chronic infection.Study design: A serological test and quantitative polymerase chain reaction (qPCR) were used on samples collected in Curacao to confirm infection. Subsequently, six samples with high viral load were selected for phylogenetic analysis. Furthermore we investigated the association of macrophage-related biomarkers during CHIKV infection with chronic arthralgia/arthritis.Results: 116 patients in Curacao were diagnosed with CHIKV infection based on ELISA and 77% were tested positive for CHIKV by qPCR. Phylogenetic analysis showed that an Asian genotype was the cause of the outbreak. Elevated levels of ferritin and CRP were significantly associated with viraemia. In addition, elevated ferritin levels were significantly associated with chronic arthralgia.Conclusions: The results showed that the presence of an Asian genotype of CHIKV in Curacao for the first time. Moreover, we found an association between ferritin levels with chronic arthralgia. (C) 2016 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license.
