In the scenarios of high disease risk in the present model, including case importation stabilizes patterns of vaccine coverage, creating greater consistency in predicted behavior for various values of <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0012594.e123.PNG" class= inline-graphic"/>.
Moreover, the imminent introduction of government regulations governing the importation of genetically modified material may affect the country's import pattern: in particular, a dampening effect on soybean imports cannot be excluded.
This study demonstrates how immigration can affect the local epidemiology of tuberculosis through importation of disease patterns from another part of the world.
At present, researchers must look to botanical garden records and both historic and current nursery catalogs to assess importation and introduction patterns of horticultural plants.
We developed a stochastic model of the transmission dynamics of measles, simulating the effects of different levels of migration, vaccination coverage and importation of new genotypes on patterns in the persistence and replacement of indigenous genotypes.
With a high importation rate (3/million/year – see Figure 3b), the distribution of patterns in persistence and replacement changed.
However, global warming and increased dog traveling and importation may potentially change the distribution patterns of European tick populations, potentially leading to spread of infectious agents, such as T. annae, to Scandinavia.
Easy importation has been important to Armon DeMarco as well.
It would be of interest to look at the similarities of viruses from each location and epidemic to establish whether the unusual epidemic patterns in Daadab result from importation of viruses from other epidemiologically distinct regions in Kenya.
We explored the relationship between measles cases over 2007 2011, by importation classification, in Quebec and Ontario in relation to global travel patterns to each province using an ecological approach.
