Species

Phlebovirus is one of four genera of the family Phenuiviridae in the order Bunyavirales. The genus currently comprises 10 species.[1] It derives its name from Phlebotominae, the vectors of member species Sandfly fever Naples phlebovirus, which is said to be ultimately from the Greek phlebos, meaning "vein".[2] The proper word for "vein" in ancient Greek is however phleps (φλέψ).[3]

Virology[edit]

Phleboviruses are viruses with a negative-sense RNA genome consisting of three segments. The small segment (S) codes for the viral N protein and a non structural protein, NSs via an ambisense coding strategy. The medium-sized segment (M) codes for a precursor of the viral glycoproteins and non-structural components. The product of the largest segment (L) is the viral RNA-dependent RNA polymerase.[4]

Taxonomy[edit]

According to the ICTV,[5] the genus Phlebovirus consists of ten species: Bujaru virus, Candiru virus, Chilibre virus, Frijoles virus, Punta Toro virus, Rift valley fever virus, Salehad virus, Sandfly fever Naples virus, SFTS phlebovirus and Uukuniemi virus.

As of 2015, within the phlebovirus there are three genetic groups of tick-borne phleboviruses : the SFTS group, the Bhanja group, and the Uukuniemi group.[6] A fourth group has been described.[7]

Clinical significance[edit]

The following twelve viruses have been linked to disease in humans: Alenquer virus,[8] Bhanja virus,[9] Candiru virus,[10] Chagres virus, Naples virus, Punta Toro virus, Rift Valley fever, Sicilian virus, Toscana virus, Uukuniemi virus, Heartland virus[11] (the first tick-borne phlebovirus known to cause disease in the Western Hemisphere, discovered in 2009), and the Sandfly Turkey virus (discovered in China in 2011).[12] They cause symptoms ranging from short self-limiting fevers, such as pappataci fever, to encephalitis and fatal haemorrhagic fever.

Serogroups[edit]

There are several recognized serocomplexes

Bhanja serocomplex[edit]

Candiru serocomplex[edit]

Frijoles serocomplex[edit]

Salehabad serocomplex[edit]

Sandfly fever serocomplex[edit]

The sandfly serocomplex is divided into two groups: Naples and Sicilian

Sandfly fever Naples group
Sandfly fever Sicilian group

Punta Toro serocomplex[edit]

Uukuniemi serocomplex[edit]

Kaisodi virus complex[edit]

Other viruses[edit]
