  Some effects of host movement in vector-borne disease systems
  Chris Cosner

  Host movements can have a profound impact on the transmission of vector-borne diseases because they can increase or reduce he rate of contact between hosts and vectors. It is clear that host movement can introduce pathogens to new environments, but models suggest that it can also increase or decrease the basic reproduction number (R0) within an environment by influencing the contact rates between hosts and infected vectors or between vectors and infected hosts. There are two distinct types of movement that are relevant in this context. They can be characterized as commuting and migration. The distinction is that migration envisions hosts changing the location of their primary residence, while commuting envisions that each host maintains a particular location of residence but visits other locations in the course of routine activities. These two types of movement require different models and may have different effects. This talk will review some models and results for the effects of host movement in vector-borne disease systems.
