Nipah virus, which can rapidly infect and kill members of a community, is carried by bats. Exactly how does it cross over into humans? Researchers in Bangladesh are trying to find out.
A few weeks later, the Centers for Disease Control and Prevention in Atlanta sent an email to Gurley and her colleagues confirming the deadly virus to be Nipah. So they wondered: Just how was the virus spilling over from bats into humans? This was the puzzle that needed solving for two reasons. First, to prevent more people from getting sick. And second, to rein the virus in.
Finally, a link emerged, but the researchers needed more evidence. In 2007, they got their chance with yet another outbreak, this time in Thakurgaon in northwest Bangladesh. Of the seven people who contracted Nipah, three were dead. People were again in a panic., an anthropologist with the icddr,b, remembers a call to join the investigation team."Our colleague called me and asked, 'Rebeca, would you like to go? Are you ready?' I said, 'Yes, I am ready to go there.
Using sticks in the dirt, the residents roughed out houses, roads, bat roosts. The shape of the outbreak gradually emerged. Soon, the villagers began sketching in date palm trees. "They said 'we all used to drink raw sap in the morning,'" she says. This was Sultana's aha moment — that patient zero had drunk raw sap before falling ill. She says this helped the researchers trace a line between the bats, the sap and the outbreaks."It's a long journey," she admits.
Early December marks the beginning of what's notoriously known as Nipah season: the four months when the virus is most likely to show up in people. This is when the date palm sap is flowing.
