evolving epidemiology of nipah virus infection in bangladesh: evidence from outbreaks during 2010-2011.drinking raw date palm sap is the primary route of nipah virus (niv) transmission from bats to people in bangladesh; subsequent person-to-person transmission is common. during december 2010 to march 2011, we investigated niv epidemiology by interviewing cases using structured questionnaires, in-depth interviews, and group discussions to collect clinical and exposure histories. we conducted a case-control study to identify risk factors for transmission. we identified 43 cases; 23 were laboratory- ...201626122675
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 variet ...201525925087
piloting the promotion of bamboo skirt barriers to prevent nipah virus transmission through date palm sap in bangladesh.drinking raw date palm sap contaminated with infected fruit bat saliva or urine is an important mode of nipah virus transmission to humans in bangladesh. bamboo skirts are an effective way to interrupt bat access to the sap. we conducted a study from november 2008 to march 2009 to explore the effectiveness of higher- and lower-intensity interventions by promoting bamboo skirt preparation and use among sap harvesters (gachhis). we spent 280 person-hours in two villages for the higher-intensity in ...201424755262
foodborne transmission of nipah virus in syrian hamsters.since 2001, outbreaks of nipah virus have occurred almost every year in bangladesh with high case-fatality rates. epidemiological data suggest that in bangladesh, nipah virus is transmitted from the natural reservoir, fruit bats, to humans via consumption of date palm sap contaminated by bats, with subsequent human-to-human transmission. to experimentally investigate this epidemiological association between drinking of date palm sap and human cases of nipah virus infection, we determined the via ...201424626480

a randomized controlled trial of interventions to impede date palm sap contamination by bats to prevent nipah virus transmission in bangladesh.drinking raw date palm sap is a risk factor for human nipah virus (niv) infection. fruit bats, the natural reservoir of niv, commonly contaminate raw sap with saliva by licking date palm's sap producing surface. we evaluated four types of physical barriers that may prevent bats from contacting sap.201222905160
epidemiology of henipavirus disease in humans.all seven recognized human cases of hendra virus (hev) infection have occurred in queensland, australia. recognized human infections have all resulted from a hev infected horse that was unusually efficient in transmitting the virus and a person with a high exposure to infectious secretions. in the large outbreak in malaysia where nipah virus (niv) was first identified, most human infections resulted from close contact with niv infected pigs. outbreak investigations in bangladesh have identified ...201222752412
piloting the use of indigenous methods to prevent nipah virus infection by interrupting bats' access to date palm sap in bangladesh.people in bangladesh frequently drink fresh date palm sap. fruit bats (pteropus giganteus) also drink raw sap and may contaminate the sap by shedding nipah virus through saliva and urine. in a previous study we identified two indigenous methods to prevent bats accessing the sap, bamboo skirts and lime (calcium carbonate). we conducted a pilot study to assess the acceptability of these two methods among sap harvesters. we used interactive community meetings and group discussions to encourage all ...201322669914
