Yes I think I understand that but when it comes to the aspects of health impacts eg malnutrition and on epidemiology eg infection estimates the content for the page on STH is going to be very very similar to the page on helminthiasis Is it OK to just do a copy  paste job in that case My tendency would be to have more information on the one page about certain aspects and less on the other rather than the same on both  About the wildlife question thats for someone else to do not my area of expertiseprofessional interest sorry
