Controlling Nipah virus encephalitis in Bangladesh: Policy options

Nipah virus (NiV) encephalitis is endemic in Bangladesh, with yearly seasonal outbreaks occurring since 2003. NiV has a notable case fatality rate, 75-100 per cent depending on the strain. In Bangladesh, primary transmission to humans is believed to be because of consumption of bat-contaminated date palm sap (DPS). Both the disease and the virus have been investigated extensively, however efforts to implement preventive strategies have met social and cultural challenges. Here we present a variety of community approaches to control the spread of Nipah encephalitis, along with advantages and disadvantages of each. This information may be useful to health workers and policymakers in potential NiV outbreak areas in Southeast Asia.
