Abstract | Chikungunya is an emerging arbovirus that is characterized into four lineages. One of these, the
Asian genotype, has spread rapidly in the Americas after its introduction in the Saint Martin island in
October 2013. Unexpectedly, a new lineage, the East-Central-South African genotype, was
introduced from Angola in the end of May 2014 in Feira de Santana (FSA), the second largest city
in Bahia state, Brazil, where over 5,500 cases have now been reported. Number weekly cases of
clinically confirmed CHIKV in FSA were analysed alongside with urban district of residence of
CHIKV cases reported between June 2014 and October collected from the municipality’s
surveillance network. The number of cases per week from June 2014 until September 2015 reveals
two distinct transmission waves. The first wave ignited in June and transmission ceased by December 2014. However, a second transmission wave started in January and peaked in May
2015, 8 months after the first wave peak, and this time in phase with Dengue virus and Zika virus
transmission, which ceased when minimum temperature dropped to approximately 15°C. We find
that shorter travelling times from the district where the outbreak first emerged to other urban
districts of FSA were strongly associated with incidence in each district in 2014 (R ). | pt_BR |
