Background With some 134,073,166 people living in endemic communities at risk of infection[1],Nigeria is the most endemic country in Africa and requires preventive chemotherapy(PC)for a total of 26.3 million persons[2].The National Schistosomiasis Elimination Programme(NSCHEP),with the support of international partners,has been implementing PC in Nigeria since 2009 and most recently will need to revise its current strategy(Additional file 1).For example,the new World Health Organization(WHO)guideline has six key recommendations that will dramatically change the implementation of schistosomiasis elimination in endemic countries[3].However,its impact and programmatic implications will vary from country to country,hence the need for a country-specific analysis.

We show by molecular dynamics simulations that configuration-sensitive molecular spectroscopy can be realized on optimally doped graphene sheets vibrated by an oscillatory electric *** selectivity of the spectroscopy is achieved by maximizing Coulombic binding between the detected molecule and a specific nest,formed for this molecule on the graphene sheet by substituting selected carbon atoms with boron and nitrogen *** can detect binding of different isomers to the nest from the frequency shifts of selected vibrational modes of the combined *** an illustrative example,we simulate detection of hexanitrostilbene enantiomers in chiral nests formed on graphene.
