“…This rate is similar to those reported in the Tunisian studies conducted between 1995 and 2008 by the national RV surveillance group (17.3-26.2 %) (Ben Hadj Fredj et al, 2012;Chouikha et al, 2009Chouikha et al, , 2011aTrabelsi et al, 2000Trabelsi et al, , 2010. Moreover, it is comparable to the detection rates reported for African countries where RV vaccine is not yet included in the free national childhood programme: 25.2 % in Egypt (Matson et al, 2010), 18 % in Tanzania (Moyo et al, 2007) and 18 % in Nigeria (Aminu et al, 2010). However, the prevalence of RVA infection in the present study is lower than those found in Morocco (42 %) (Benhafid et al, 2013), Cameroon (42.8 %) (Ndze et al, 2012), southern Ghana (48.2 %) (Enweronu-Laryea et al, 2013), south-eastern Nigeria (56 %) (Tagbo et al, 2014) (Sowmyanarayanan et al, 2012).…”
