Survival rates for juvenile cotton rats (A), mature cotton rats (B), and house sparrows (C) after subcutaneous inoculation with ≈3–4 log10 PFU of North American eastern equine encephalitis virus (EEEV) strain FL93 (red lines), South American (SA) EEEV strain PE70 (blue lines), or SA EEEV strain CO92 (green lines). Survival rates beyond day 22 postinfection did not differ. Experimental infection of juvenile cotton rats with SA EEEV strain CO92 was not conducted.
