| Abstract | Chikungunya virus (CHIKV) entered Brazil in 2014, causing a large outbreak in Feira de Santana, state of Bahia. Although cases have been recorded in Salvador, the capital of Bahia, located ~100 km of Feira de Santana, CHIKV transmission has not been perceived to occur epidemically, largely contrasting with the Zika virus (ZIKV) outbreak and ensuing complications reaching the city in 2015. Methodology/Principal Findings
This study aimed to determine the intensity of CHIKV transmission in Salvador between
November 2014 and April 2016. Results of all the CHIKV laboratory tests performed in the
public sector were obtained and the frequency of positivity was analyzed by epidemiological
week. Of the 2,736 tests analyzed, 456 (16.7%) were positive. An increasing in the positivity
rate was observed, starting in January/2015, and peaking at 68% in August, shortly after the
exanthematous illness outbreak attributed to ZIKV.
Conclusions/Significance
Public health authorities and health professionals did not immediately detect the increase in
CHIKV cases, likely because all the attention was directed to the ZIKV outbreak and ensuing
complications. It is important that regions in the world that harbor arbovirus vectors and did
not experience intense ZIKV and CHIKV transmission be prepared for the potential coemergence
of these two viruses. | pt_BR |
