Estimates of the basic reproductive number, R 0, of clade 2.3.4.4 highly pathogenic hemagglutinin (H5) segment 2014–2015 in North America. Probability density distributions represent the Bayesian posterior estimates of R 0 for all poultry and domestic bird hosts sampled 2 December 2014 – 1 June 2015 and wild bird hosts by highly pathogenic avian influenza virus (HPAIV) subtype sampled 2 December 2014 – 1 February 2015 to estimate dynamics when there was epidemiological evidence of wild bird transmission (Lee et al., 2015)
