The Haitian government has temporarily banned the import of live pigs from the Dominican Republic and other countries due to the presence of Viral Porcine Diarrhea, which affects pigs but not humans.
In a press release, the Haitian Agriculture Minister said that the disease was caused by a virus which is present in the Dominican Republic, the United States, Canada, Brazil and Mexico and that they did not want it to come to Haiti as they had over a million pigs and a new disease would have a significant effect on the national economy. In Santo Domingo, the Dominican Livestock Commission confirmed that there had been cases of Porcine Diarrhea in some areas of the country but that it was now under control.
