its a bit confusing. the terms +/-ve strandedd are used for RNA viruses and linear/circular for DNA viruses, so how can an RNA virus be non linear/linear?

Arenavirus has two circular RNA segments, one negative sense and one ambisense, but it is enveloped.

I thought all negative sense RNA viruses were helical and enveloped.

the only - rna circular virus i know is HDV, but it has the same envelope as HBV. :roll:
