“…Of the 388 eligible articles, 183 were excluded for multiple reasons described in Figure 1. Finally, a total of 205 articles (629 data on prevalence and/or CFR) met the inclusion criteria for this systematic review (Abakar et al., 2014; Abdallah et al., 2016; Adamu, 2020; Adamu et al., 2021; Adesiyun et al., 2020; Ahmed et al., 2018, 2020; Alhaji, 2020; Andayi et al., 2014; Andriamandimby et al., 2010; Andriamandimby et al., 2018; Aradaib et al., 2013; Archer et al., 2011, 2013; Atuman et al., 2022; Ayari‐Fakhfakh et al., 2011; Ba et al., 2012; Baudin et al., 2016; Beechler et al., 2015; van den Bergh et al., 2022; Bett et al., 2019; Bird et al., 2008; Bisimwa et al., 2016; Bloland et al., 2010; Blomstrom et al., 2016; Bob et al., 2017, 2022; Bonney et al., 2013; Bosworth et al., 2016; Boushab et al., 2015, 2016; Boussini et al., 2013, 2014; Breiman et al., 2010; Budasha et al., 2018; Budodo et al., 2020; Bukbuk et al., 2014; Centers for Disease Control and Prevention 2007; Chambaro et al., 2022; Chengula et al., 2014; Chevalier et al., 2005, 2011; Cichon et al., 2021; Clements et al., 2019; Cook et al., 2017; Cosseddu et al., 2021; Di Nardo et al., 2014; Diallo et al., 2005; Dione et al., 2022; Dondona et al., 2016; Durand et al., 2003, 2020; Dutuze et al., 2020; Ebogo‐Belobo et al., 2022; Eckstein et al., 2022; El Bahgy et al., 2018; El Mamy et al., …”

“…The pooled RVF prevalence in humans was estimated to be 7.8% [95% CI = 6.2–9.6] based on a sample of 102,427 participants. RVF prevalence data displayed presented substantial heterogeneity among the studies ( I 2 = 99.0% [95% CI = 98.9–99.0], p < 0.0001) (Adamu et al., 2021; Ahmed et al., 2018, 2020; Andayi et al., 2014; Andriamandimby et al., 2010; Aradaib et al., 2013; Archer et al., 2011, 2013; Atuman et al., 2022; Baudin et al., 2016; van den Bergh et al., 2022; Bett et al., 2019; Bloland et al., 2010; Bob et al., 2017, 2022; Bonney et al., 2013; Bosworth et al., 2016; Boushab et al., 2015; Breiman et al., 2010; Budodo et al., 2020; Bukbuk et al., 2014; Chambaro et al., 2022; Cichon et al., 2021; Clements et al., 2019; Cook et al., 2017; Cosseddu et al., 2021; Dione et al., 2022; Durand et al., 2003; Eckstein et al., 2022; Enem et al., 2020; Faye et al., 2007; Fokam et al., 2010; Gray et al., 2015; Grolla et al., 2012; Grossi‐Soyster et al., 2017; Gudo, Lesko, et al., 2016; Gudo, Pinto, et al., 2016; Guillebaud et al., 2018; Hassan et al., 2020; Hassanain et al., 2010; Heinrich et al., 2012; Ibrahim et al., 2021; Labeaud et al., 2008; Labeaud, Muiruri, et al., 2011; Labeaud et al., 2015; Muiruri et al., 2015; Lagare et al., 2019; Lysholm et al., 2022; Macharia et al., 2010; Mahmoud & Ali, 2021; Makiala‐Mandanda et al., 2018; Marrama et al., 2005; Mease et al., 2011; Mohamed et al., 2019; Msimang et...…”

“…However, in some studies reporting RVF CFR, many people who died had at least one complication that appeared to be the mains causes of human mortality. These complications include particularly haemorrhagic syndrome (Adam et al., 2010 ; Al‐Hazmi et al., 2005 , 2003 ; Boushab et al., 2016 , 2015 ; Madani et al., 2003 ; Rakotoarivelo et al., 2011 ) but also acute hepatic or renal failure (Anywaine et al., 2022 ).…”

Epidemiology and serological detection of Rift Valley Fever disease in farm animals in southern Egypt

“…Rift Valley Fever (RVF) is a vector-borne viral disease caused by Rift Valley Fever virus (RVFV), a member of the Bunyaviridae family and Phlebovirus genus that primarily affects domestic ruminants, causing large epizootics with high mortality rates in young animals and abortions in affected dams (Mansfield et al 2015;Shabani et al 2015). The virus was discovered in 1930 during an outbreak that affected livestock in East Africa (Daubney & Hudson 1931;Boushab et al 2015). Six years later, RVFV antibodies were found in human sera from southern Sudan (Findlay et al 1936).…”

“…The primary major human epidemic occurred in 1951 in South Africa (Tolou et al 2009). Since then, multiple outbreaks were reported in several parts of Africa and the Middle East, notably in Egypt (1977Egypt ( , 2003 (Faye et al 2007;Sissoko et al 2009), Kenya (1997)(1998)(2006)(2007) (Faye et al 2010), Saudi Arabia and Yemen (2000-2001 (Al-Hazmi et al 2003;Nabeth et al 2001), Sudan (2007 (Hassan et al 2011;Nabeth et al 2001), Mayotte (2008) (Sissoko et al 2009) and Mauritania (1987, 1993-1994, 1998, 2003, 2010, 2012) (Boushab et al 2015;Faye et al 2007;Nabeth et al 2001).…”
