Emergence of Epidemic Neisseria meningitidis Serogroup X Meningitis in Togo and Burkina Faso
Figure 4
District level etiology distribution among PCR-confirmed bacterial meningitis cases from surveillance in Burkina Faso, 2010.
Circle size is proportional to the seasonal cumulative incidence in the districts (January–June). Black spots indicate districts with reported epidemics during 2010. The white colored circles are epidemic districts for which the etiology distribution is not available for this report. Numbers in circles represent the total number of confirmed cases in epidemic districts if the total number was less than 15.
