Enterovirus D68 Subclade B3 Circulation in Senegal, 2016: Detection from Influenza-like Illness and Acute Flaccid Paralysis Surveillance

Figures

• 

  Figure 1. Distribution of EV-D68 in Senegal, from June to September 2016. The unbroken line represents the number of specimens collected per weeks. The shaded bars show EV-D68-positive specimens from patients with ILI (in blue) and AFP (in red).

• 

  Figure 2. Geographical distribution of EV-D68 in Senegal with red dots representing strains from AFP patients, blues dots strains from ILI patients, the number of EV-D68 positive sample are written in dots.

  Figure 3. The partial sequences of VP1 region of EV-D68 were analyzed and used for a maximum likelihood phylogram. The phylogenetic tree was constructed by maximum likelihood estimation method with 1,000 bootstrap replicates using MEGA 7.0 software. The evolutionary distances were derived using the Tamura 3 parameter model. Numbers at nodes, which indicate bootstrap support values (≥70%), are given. Sequences in GenBank were also included in the analysis. Strain name, country of origin, year of detection and accession numbers are shown for each strain. Sequences of EVD68 strains from Senegal are depicted in blue with the red dots symbolizing strains from AFP patients and the blue ones strains from ILI patients.
