Tzim geziint
"Будь здоров!" (pronounced "bood' zdorov") which means "be healthy" is a common phrase used in Russia or "На здоровье!" (pronounced "na zdorovye") which means "to your health".
Most people say Salud
When someone sneezes the common response is "bless you".
Yes.
It means "Bless you"... Like when someone sneezes, you would say "Gusuntite"
BLESS YOU! (english), SANATATE! (Romanian) ...
I think Americans say 'Gazumptite' (I'm not sure if that's how you spell it).
Germs
It depends on how frequent the sneezes are. If you would like to be courteous (and/or professional) three responses would be appropriate if made within a 5 minute window.
Yia sas means goodbye in Greek. It also means hello, and can be used to say bless you after someone sneezes.
