It's a general greeting that can be used in most situations.
Here are some other ways to say hello in Swahili, depending on the context:
* "Habari" - This is a more formal greeting, similar to "How are you?" in English.
* "Shikamoo" - This is a respectful greeting used when meeting someone older or of higher status.
* "Mambo" - This is a more casual greeting, often used among friends and family.
* "Hujambo" - This is a more literal translation of "How are you?"
You can also add "sana" after any of these greetings to make it more emphatic, for example: "Jambo sana!" (Hello very much!).
