Can I say "biological threat" instead of "biological hazard"?

Yes, you can! You can use "threat" instead of "hazard" without changing the meaning of the sentence significantly. In fact, "threat" sounds more natural than "hazard" in this context. Ex: The virus is a serious biological threat. Ex: There are various biological hazards in this area, so you have to be careful and wear a hazmat suit.
