Hypotheses for Iberian hare susceptibility to MYXV and MYXV‐related viruses. (a) Hares are not susceptible to infection by MYXV strains. (b) Hares are susceptible to MYXV if exposed to high infectious doses or if immunodepressed. (c) Hares are infected by MYXV, but develop subclinical disease. (d) ha‐MYXV emerged in hares infected with rabbit strains, by a recombination event that increased virulence of the virus towards hares. (e) ha‐MYXV emerged in hares after a species jump event, involving or not, an intermediate host. (f) ha‐MYXV emerged in hares from a low virulent strain that has circulated unnoticed in the population
