Abstract

Low pathogenic influenza A virus (LPIAV) prevalence and subtype distribution differs between and across bird taxa. A crucial factor in the epidemiology of these viruses and virus subtypes is the ability to transmit between and within different host taxa and individuals. Successful viral transmission depends on availability of susceptible hosts and exposure of host to virus. Exposure to viruses and susceptibility to virus infection and/or disease are shaped by both host and virus traits. In this review we have identified key host and virus traits that can affect LPIAV transmission, both in terms of exposure and susceptibility. Furthermore we highlight current challenges in assessment of these traits and identify methodological considerations for future studies.
