FIG 1 — Transmission kinetics of A(H1N1) viruses in ferrets. (A) Normalized viral loads of donors (left bars) and aerosol contact ferrets (right bars) after inoculation or exposure to A(H1N1)pdm09 virus Cal/09. (B) Normalized viral loads of donors (left bars) and aerosol contact ferrets (right bars) after inoculation or exposure to avian H1N1 virus ruddy turnstone/09. Nasal washes (all groups except group F) or throat swabs (group F) were sampled to determine infectious viral loads, which were normalized to log₁₀ TCID₅₀ per milliliter. Each bar represents an individual ferret. The limit of detection is indicated with a dashed line.
