Overview
Causes
- RVF is caused by the Rift Valley fever virus or RVFV, which belongs to the Bunyaviridae family.
- The genetic composition of the virus is a single-stranded RNA consisting of three segments (L, M and S) out of which L and M possess a negative charge while the S segment has both sense and antisense orientation.[1]
- The virus’ RNA polymerase is coded by the L component which is responsible for replication and transcription of messenger RNA (mRNA) while glycoproteins and protein are encoded via the M segment. [2]
- Nucleoproteins and non-structural proteins are coded by the S segment in its antisense and sense orientation respectively.
