(a) Virus titres in nasal wash samples from individual donor ferrets (black), direct-contact (DC) ferrets (blue) and respiratory-droplet (RD) ferrets (red). Arrows indicate the day (day 1 p.i for donors) when recipient ferrets were housed with donor ferrets. (b) Virus titres in DC ferret nasal wash samples at day 1 post contact. Each dot represents an individual ferret. *P<0.05, two-tailed t-test, versus MEM/13. (c) Virus titres in RD ferret nasal wash samples on the first day of detection (the day post contact), which is indicated above each column.
