“…It especially in exotic and crossbred animals, and has been responsible for several outbreaks of disease in East Africa (Baron and Holzer, 2015). The virus has also been identified in South Asia (India and Sri Lanka), where it is known as Ganjam virus (Marczinke and Nichol, 2002;Perera et al, 1996). NSDV infection of humans can cause a mild disease with symptoms such as fever, headache, nausea and vomiting, and therefore classifies as a zoonotic pathogen (Dandawate et al, 1969b).…”

Genomes and seroprevalence of severe fever with thrombocytopenia syndrome virus and Nairobi sheep disease virus in Haemaphysalis longicornis ticks and goats in Hubei, China

A B S T R A C TTicks are medically-important arthropods that maintain and transmit numerous emerging viruses. China suffers severely from tick-borne viral diseases such as tick-borne encephalitis and severe fever with thrombocytopenia syndrome (SFTS), but the background of tick-borne viruses is very limited. Here we report the virome profiling of ticks and goat sera from SFTS-epidemic areas, and serological investigation of SFTS virus (SFTSV) and Nairobi sheep disease virus (NSDV). Results revealed divergent viruses in ticks and goat sera, including SFTSV and NSDV. Sequence and phylogenetic analyses showed that the SFTSV identified here was most closely related to human SFTSV in sampling and surrounding areas, and the NSDV to the previously identified NSDV from northeast China. Serological investigation of SFTSV infection in goats revealed intensive activity in those areas. Surprisingly, two different methods of NSDV serological investigation showed no sera positive for this virus.

“…Outbreaks are often related to movements of non-immune herds in endemic areas. The vims belongs to the genus Nairovirus and is now recognised to be indistinguishable from Ganjam, a vims isolated from Haemaphysalis intermedia ticks in India and Sri Lanka, which causes a similar disease in sheep and goats (34). Occasional cases of human disease, with pyrexia, headache and abdominal pains, have been described in laboratory workers.…”

Rift Valley fever is the most important bunyaviral disease of animals in Africa. The virus, transmitted by mosquitoes, causes abortions and mortality in young animals in addition to haemorrhagic fevers in humans. Although vaccines against this virus are available, the uses of these vaccines are limited because of deleterious effects or incomplete protection, justifying further studies to improve the existing vaccines or to develop others. Nairobi sheep disease is transmitted by ticks. The disease is endemic in East Africa and sporadic cases are reported in India and Sri Lanka. Other viruses transmitted by mosquitoes or midges are teratogenic in cattle or sheep, these include Akabane and related viruses in Asia, Australia and the Middle East, and Cache Valley in North America. The Marburg and Ebola viruses of the genus Filovirus are associated with epidemics in Central Africa with high fatality rates in humans; some outbreaks were related to contact with monkeys. Another subtype of Ebola virus was first described in a quarantine facility in the United States of America among cynomolgus monkeys (Macaca fascicularis) from the Philippines. The reservoir of these viruses remains unknown.

“…Although the occurrence of NSDv has been reported in numerous countries (16,26–32), there has been limited understanding of the biogeographic factors shaping its distribution and the potential areas at risk for future epidemics. The available literature on NSDv ranges from 1910 to 2019, with host serology and virus isolation found in 14 of these studies (Table S1 in Supplementary Material).…”

“…The first human infection was recorded in a young boy (41) and some laboratory acquired infections occurred in following years (42,43). Human sera has been shown to contain antibodies against NSDv in India (41,44), Uganda (29), Kenya (45), and Sri Lanka (32). Other isolates have also been obtained from different vector species such as Culex vishnui mosquitoes, where the virus was unable to replicate without a tick host (46), Haemaphysalis wellingtoni ticks feeding on red spurfowl ( Galloperdix spadicea ) (47), and from a pool of Culicoides 23 midges (48) and Culicoides tororensis, although this could be due to blood meal residues in the midges (49).…”

“…Similarities between NSDv and Ganjam virus were highly debated due to their occurrence on different continents and association with different vectors, but genetic and serologic analyses demonstrated that Ganjam virus is an Asian variant of NSDv, instead of a different virus as previously described (23,52–54). NSDv was first isolated on the Asian continent in 1954 from H. intermedia in India (26) and Sri Lanka in 1996 (32). More recently, Gong et al (16) were the first to discover NSDv present in H. longicornis ticks in China.…”

16Nairobi Sheep Disease virus (NSDv) is a zoonotic and tick-borne disease that can cause over 90% mortality in small ruminants. NSDv has 17 historically circulated in East Africa and has recently emerged in the Asian continent. Despite efforts to control the disease, some regions, mostly 18 in warmer climates, persistently report disease outbreaks. Consequently, it is necessary to understand how environmental tolerances and factors
