In Bangladesh, “We found that in the areas where most of the cases were happening [the forest] was really fragmented,” Hahn says. Although there are date palms all over the country and drinking palm sap is as common as having a beer in the evening, she says, areas with Nipah issues had people and bats living in closer proximity, the result of deforestation for farming, timber, or to make way for human settlement. “These bats are roosting in people’s backyards, essentially,” Hahn says. Areas with more space saw less of the disease. Hahn’s team is working to help farmers figure out how to keep bats out of their palms so the virus doesn’t spread.
