Outline of Final Research Achievements

The aim of this study was to determine the etiology of non-Ebola virus disease (EVD) cases, which showed EVD-like clinical signs, but were excluded viral infection by a laboratory testing, in the recent endemic of the disease in West Africa. In the collaboration with the National Donka Hospital in Guinea, we conducted screening detection of viruses which causes systematic febrile illness and malaria on the 71 samples from non-EVD cases. We detected dengue virus, enteroviruses, measles virus, and malaria positive cases in these samples, and determined the genotype of the detected viruses using partial or whole genome sequences by Sanger or next generation sequencing. These results suggested that these viruses and malaria caused clinical symptoms similar to EVD, and should be differentiated from EVD in clinical and laboratory diagnosis. Furthermore, these results suggested that these viral diseases have been endemic in Guinea.
