Introduction CCHFV (Crimean-Congo hemorrhagic fever virus) is one of the most widespread arthropod-borne viruses present in western parts of China, southern Asia, the Middle East, southwestern and southeastern Europe as well as throughout most parts of the African continent (Bente et al., 2013). CCHFV is primarily transmitted by ticks of the genus Hyalomma. Other possible transmission pathways are contacts to infectious blood, body fluids, or tissue. Hyalomma ticks serve as vectors as well as main reservoir (Gargili et al., 2017), as infected vertebrate hosts develop only a short viremias (Spengler et al., 2016). Currently, there are 27 different Hyalomma species described (Horak et al., 2002; Sands et al., 2017).

Abstract Background Despite several studies on the seroprevalence of antibodies against Crimean-Congo Haemorrhagic Fever virus (CCHFV) from humans and cattle in Nigeria, detailed investigation looking at IgG and IgM have not been reported.
Additionally, there have been no confirmed cases of human CCHFV infection reported from Nigeria. Principal Findings Samples from sera (n = 1189) collected from four Local Government Areas in Borno State (Askira/Uba, Damboa, Jere and Maiduguri) were assessed for the presence of IgG and IgM antibodies. Conclusions This article provides evidence for the continued exposure of the human population of Nigeria to CCHFV.

Crimean-Congo Haemorrhagic Fever Virus (CCHFV) is a member of the Nairovirus genus of the family Bunyaviridae that can be transmitted to humans.
This arbovirus is transmitted by Ixodid ticks and causes a highly pathogenic disease called Crimean Congo hemorrhagic fever (CCHF) with up to 50 % mortality rate in humans [1, 2]. At least 28 species of the Ixodid ticks distributed among 7 genera, (Hyalomma, Rhipicephalus, Boophilus, Dermacentor, Ambylomma, Haemaphysalis, and Ixodes) have been found to be naturally infected with CCHF virus worldwide [3, 4]. Crimean Congo hemorrhagic fever (CCHF) is endemic to Africa, the Balkans, the Middle East, and parts of Asia. Although the hard ticks (Ixodids) serve as reservoirs and vectors for CCHFV, a variety of animals, such as cattle, sheep, goat and camels, are considered amplifying hosts for the virus. Several factors influence CCHF morbidity and mortality. Crimean-Congo Hemorrhagic Fever with Acute Subdural Hematoma, Mauritania, 2012 - Volume 22, Number 7—July 2016.
Suggested citation for this article To the Editor: Crimean-Congo hemorrhagic fever (CCHF) was first described in Crimea in 1944 and in the Congo in 1969.
Since then, many cases in humans have been reported from different regions (1–3). The disease is transmitted to humans through the bite of an infected tick or by direct contact with blood or tissue from infected humans and livestock. We report an unusual case of acute subdural hematoma secondary to CCHF. A 58-year-old man, a shepherd, was admitted to Centre Hospitalier National (Nouakchott, Mauritania) on July 2, 2012, with fever and epistaxis.
Treatment with platelet transfusions and supportive therapy was initiated. Our care team considered a conservative management approach. The main vector for CCHF virus transmission appears to be ticks from the genus Hyalomma (2). Brain hemorrhage in persons with CCHF is rare. Death from CCHF usually occurs after 5–14 days of illness (1,8,9). References Figure Figure. CDC EID - Volume 22, Number 2—February 2016. Au sommaire notamment: AP92-like Crimean-Congo Hemorrhagic Fever Virus in Hyalomma aegyptium Ticks, Algeria. Suggested citation for this article To the Editor: Crimean-Congo hemorrhagic fever virus (CCHFV) (Nairovirus, Bunyaviridae), the causative agent of Crimean-Congo hemorrhagic fever, has been detected in sub-Saharan Africa, southeastern Europe, the Middle East, and central Asia.
The virus has been detected in >31 species of ticks and is transmitted to humans by bite of infected ticks (mainly of the genus Hyalomma) or by contact with body fluids or tissue of viremic patients or livestock. The disease is characterized by fever, myalgia, headache, vomiting, and sometimes hemorrhage; reported mortality rate is 10%–50% (1). CCHFV strains currently constitute 7 evolutionary lineages, 1 of which (Europe 2) contains the prototype strain AP92, which was isolated in 1975 from Rhipicephalus bursa ticks collected from goats in Greece (2). This strain seems to have low or no pathogenicity for humans; only a few mild cases have been reported (3).
In total, 16 (28.6%) ticks were positive for CCHFV. CDC EID - MAI 2014 - Au sommaire: Unique Strain of Crimean–Congo Hemorrhagic Fever Virus, Mali. Suggested citation for this article To the Editor: Crimean-Congo hemorrhagic fever (CCHF) is an acute viral infection that causes mild to severe hemorrhagic fever characterized by petechiae, ecchymosis, disseminated intravascular coagulation, and multi-organ failure (1).
The etiologic agent, CCHF virus (CCHFV; family Bunyaviridae, genus Nairovirus), is maintained in enzootic cycles involving agricultural and wild animals and the vector, Hyalomma ticks. (2). CCHF predominantly affects persons who have 1) substantial contact with ticks and/or agricultural animals in areas where CCHF is endemic or 2) close contact with infected persons, predominantly close relatives and health care workers. The case-fatality rate for CCHF is generally accepted as 30% (1). CCHF has a wide geographic distribution; cases have been reported in >30 countries across Africa, southeastern Europe, the Middle East, and western Asia.

Highlights. UNIVERSITY OF THE FREE STATE 20/05/15 Researchers receive study grant for research into Congo Fever (Afrique du Sud) UFS researchers will be contributing significantly to the search for a vaccine against the deadly tick-borne disease known as Congo Fever.
Prof Felicity Burt from the Department of Medical Microbiology and Virology was recently awarded a research grant by the National Health Laboratory Service (NHLS) to study candidate vaccines for Crimean-Congo haemorrhagic fever (CCHF) virus and other arboviruses. Arboviruses are viruses transmitted by mosquitoes, ticks, or other arthropods. Prof Burt is an internationally recognised expert on the CCHF. The CCHF virus is a tick-borne virus that is associated with severe haemorrhagic disease, found in South Africa and other parts of Africa, Asia, and eastern Europe. Prof Burt's interests focus on medically significant viruses that are transmitted by ticks and mosquitoes. CCHF virus causes severe viral haemorrhagic fever outbreaks.

Abstract Background Crimean-Congo hemorrhagic fever (CCHF) activity has recently been detected in the Kordufan region of Sudan. Since 2008, several sporadic cases and nosocomial outbreaks associated with high case-fatality have been reported in villages and rural hospitals in the region. Principal Findings In the present study, we describe a cluster of cases occurring in June 2009 in Dunkop village, Abyei District, South Kordufan, Sudan. Conclusions The present investigation illustrates that multiple CCHF virus lineages are circulating in the Kordufan region of Sudan and are associated with recent outbreaks of the disease occurring during 2008–2009.
