FIG. 1.

Geographic and temporal variation in MicrosatI reveals the stable maintenance of site-specific strains in U.S. military recruit training centers. This figure shows the allele identity distribution of MicrosatI among 68 febrile respiratory illness patients at seven Army, Navy, Air Force, and Marine Corps recruit training centers and three Air Force advanced training centers, collected during the outbreaks of 2006 and 2007, by site and date (the full names of these sites appear in Materials and Methods). The black arrow represents the flow of trainees from recruit training to advanced training centers, the most likely route of adenoviral transmission to those sites.
