Can i get polio if i do a manicure on someone who is 67 and has had it most of her life?

No: Polio is a long term problem, but is only contageous long before it develops. The problem occurs weeks/months after a viral illness, that produces contageous particles in the poo. That illness and the contageous period stops within weeks, often before the first signs of paralysis occur.Neither you or anybody around you are at risk providing a service to this lady.
