The infection agent The reservoir host The portal of exit The route of transmission The portal of entry The susceptible host. The structure of the pig production chain in high technology pig husbandry enables pathogens to spread during animal trading, with an increasing prevalence in herds further down the chain. This is called the chain of infec-tion (CDC, 2016), which is shown in Fig 1. One framework for understanding this complex relationship is the chain of infection, which can have six links (as shown in Figure 1a): the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry and susceptible host. a decrease in MRSA transmission as well as a decrease in other HAIs. The specific preventative measures used will depend on the pathogen and its mode of transmission, however the following list offers some suggested . The chain of infection, if we think of it as an actual chain, is made up of six different links: pathogen (infectious agent), reservoir, portal of exit, means of transmission, portal of entry, and the new host.
