Corvid 19 and self employment

muddypixie

I'm a self-employed in a couple of schools and very small businesses. If they close due to corvid 19 are there any benefits I can apply for (universal credit?) until they reopen and U can return to work? I read somewhere that the government can give small businesses £3k grants but I don't know if I'd be eligible as a sole trader and can't find any further information about it or how I'd apply if the schools/businesses I work for do close
