Moreover, “[a]ccording to this model, the agent, host, and environment can coexist” (Anderson & Mcfarlane, 2011, p. 44). It is when there is no balance among them that disease can take place. The following are the agent and hosts. The infectious agent in case of swine flu is virus H1N1, which is a subtype of influenza A virus, the latter being a common and much less harmful cause of flu among humans. Hosts are individuals that have contact to animal hosts of the H1N1 virus, such as pigs. Similarly, in case of avian flu, another strain of influenza A hosts were birds, as infections took place, “in or near known wintering sites for migratory birds” (Gilbert et al., 2006, p.1650). Moreover, individuals with low immune system levels can easily become hosts. Environment is crucial in transmission of the virus and incidence levels. According to Tellier (2006), “influenza viruses can be transmitted by 3 routes: aerosols, large droplets, and direct contact with secretions (or with fomites)” (p.1659). ...
