In 2014 an outbreak of the Ebola virus occurred in Guinea. In response, the health ministry banned the sale and consumption of bats, thought to be carriers of the disease. Despite this measure, the virus eventually spread from rural areas to Conakry, and by late June 2014 had spread to neighboring countries - Sierra Leone and Liberia. In early August 2014 Guinea closed its borders to Sierra Leone and Liberia to help contain the spread of the virus, as more new cases of the disease were being reported in those countries than in Guinea.
