Phlebovirus is one of five genera of the family Bunyaviridae. The Phlebovirus genus currently comprises over 70 antigenically distinct serotypes, only a few of which have been studied. 68 of the known serotypes are divided into two groups: the Phlebotomus fever viruses (the sandfly group, transmitted by Phlebotominae sandflies) comprises 55 members and the Uukuniemi group (transmitted by ticks) comprises the remaining 13 members.

Virology

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.[1]

Taxonomy

According to the ICTV,[2] the genus Phlebovirus consists of nine species: Bujaru virus, Candiru virus, Chilibre virus, Frijoles virus, Punta Toro virus, Rift valley fever virus (the type species), Salehad virus, Sandfly fever Naples virus 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.[3]

Clinical Significance

The following twelve viruses have been linked to disease in humans: Alenquer virus,[4] Bhanja virus,[5] Candiru virus,[6] Chagres virus, Naples virus, Punta Toro virus, Rift Valley fever, Sicilian virus, Toscana virus, Uukuniemi virus, Heartland virus[7] (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).[8] They cause symptoms ranging from short self-limiting fevers, such as pappataci fever, to encephalitis and fatal haemorrhagic fever.

Serogroups

There are ten recognised serocomplexes

Aguacate serocomplex

Bhanja virus serocomplex

Candiru serocomplex

Frijoles serocomplex

Icoaraci serocomplex

Salehabad serocomplex

Sandfly fever serocomplex

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

Sandfly fever Naples group
Sandfly fever Sicilian group

Simbu serocomplex

Punta Toro serocomplex

Uukuniemi serocomplex

Unclassified viruses
