Horizontal transmission of the H5N6 viruses between guinea pigs. Groups of three guinea pigs were inoculated with the indicated viruses. The next day, the inoculated animals were paired by co-housing with direct-contact guinea pigs; aerosol-transmission animals were also housed in a wire-frame cage adjacent to the infected guinea pigs. Nasal washes were collected from all the animals for virus shedding detection every other day beginning on day 2 after the initial infection. Each color bar represents the virus titer in an individual animal. Dashed lines indicate the lower limit of virus detection.
