Figure 1. Sites at which Mastomys natalensis rodents were captured in Nigeria during January 2011–March 2013. Red circles represent sites within the Lassa fever–endemic zone; black circles represent sites outside the Lassa fever–endemic zone. Within the circles, gray indicates M. natalensis phylogroup A-I rodents; white indicates M. natalensis phylogroup A-II rodents; both colors within 1 circle indicate that rodents of both phylogroups were present at that site. Numbers under each site indicate number of arenavirus-positive M. natalensis rodents/number of M. natalensis captured. L indicates sites with Lassa virus–positive M. natalensis rodents; M indicates sites with Mobala-like virus–positive M. natalensis rodents.
