'Para asegurar el cumplimiento de las metas del proyecto se hará una coordinación efectiva con las unidades de salud de las comunidades y subsedes.'

'...11 comunidades de más alta prevalencia de malaria ubicada en 4 sub sedes.'

'Sub sedes de atención para comisiones municipales' - this is a heading in a table.

Nicaraguan Spanish to UK English. This is a recurring term in an application form to request funding. It seems to refer to a level of administration within the country, but I can't quite work out what level (although I think it is rather local) or how I would best render it in English. I know that Nicaragua is divided into departments and regions and that these are sub-divided into municipalities. The text also refers to 'comunidades' and 'territorios indígenas'. Are there any Nicaraguans out there who might be able to explain exactly what a 'sub sede' is?

Thank you!
