Fig. 3.

Six ferrets were inoculated i.n. with 6.0 log10 PFU of Hunan/42443 virus. The following day, a naïve ferret was placed in each of the three cages housing an inoculated ferret for the direct contact transmission model (A) and in an adjacent cage to each of the 3 remaining animals for the respiratory droplet transmission model (B). Nasal wash specimens were collected from both the inoculated (left side of each panel) and contact ferrets (right side of each panel) every other day post inoculation or post contact for titration by plaque assay. Titers of individual ferrets are expressed as log10 PFU/ml. The limit of detection is 10 PFU (dashed line).
