I don't think they're the same at all. 一定 more or less translates to "certainly, necessarily, surely", whereas 需要 very strictly means "need".
So in the other example, "一定是感冒了" translates to something like must be (certainly is, surely is, etc) a cold.
Perhaps because it has two "yào" syllables. Chinese has a massiv supply of homophones.
