A case of imported dengue fever from Burkina Faso to Japan in October 2016

抄録

Dengue fever remains underreported in Africa due to lack of awareness among healthcare providers, the presence of other febrile illnesses, and insufficient laboratory testing. We present a case of imported dengue fever from Burkina Faso to Japan, where an outbreak of dengue was reported on October 18, 2016. The phylogenetic analysis revealed that the isolate from our patient belonged to a distinct of sylvatic dengue viruses, suggesting that dengue viruses have been maintained in the mosquitoes and human cycles in Burkina Faso for more than 30 years.
