Among livestock, outbreaks of the disease are\u00a0economically devastating. They are often characterised by large, sweeping abortion storms and\u00a0have significant mortality in adult livestock. The aim of the current study was to investigate\u00a0RVFV infection in the Kigoma region, which is nestled under the hills of the western arm of the\u00a0Great Rift Valley on the edge of Lake Tanganyika, Tanzania. A region-wide serosurvey was\u00a0conducted on non-vaccinated small ruminants (sheep and goats, n = 411). Sera samples were\u00a0tested for the presence of anti-RVFV antibodies and viral antigen, using commercial enzyme-linked immunosorbent assay and reverse transcriptase polymerase chain reaction, respectively.\u00a0The overall past infections were detected in 22 of the 411 animals, 5.4% (Confidence Interval\u00a0(CI) 95%\u00a0= 3.5% \u2013 8.1%). The Kigoma rural area recorded the higher seroprevalence of 12.0%\u00a0(CI 95% = 7.3% \u2013 18.3%; p &lt; 0.0001), followed by Kibondo at 2.3% (CI 95%\u00a0= 0.5% \u2013 6.5%;\u00a0p &gt; 0.05) and the Kasulu district at 0.8% (CI 95%\u00a0= 0.0% \u2013 4.2%; p &gt; 0.05). The prevalence\u00a0was 12.5% and 4.7% for sheep and goats, respectively. Reverse transcriptase polymerase chain\u00a0reaction results indicated that only eight samples were found to be positive (n = 63). This study\u00a0has confirmed, for the first time, the presence of the RVFV in the Kigoma region four years\u00a0after the 2007 epizootic in Tanzania. The study further suggests that the virus activity exists\u00a0during the inter-epizootic period, even in regions with no history of RVFV.<\/jats:p>","DOI":"10.4102\/ojvr.v81i2.717","type":"journal-article","created":{"date-parts":[[2014,4,23]],"date-time":"2014-04-23T11:53:05Z","timestamp":1398253985000},"source":"Crossref","is-referenced-by-count":16,"title":["Epidemiological study of Rift Valley fever virus in Kigoma, Tanzania"],"prefix":"10.4102","volume":"81","author":[{"given":"Emmanuel G.","family":"Kifaro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Japhet","family":"Nkangaga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gradson","family":"Joshua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raphael","family":"Sallu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mmeta","family":"Yongolo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Dautu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher J.","family":"Kasanga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2014,4,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-8579(02)00295-9"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.01519-08"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1603\/0022-2585(2000)037%5b0435:LTORVF%5d2.0.CO;2"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(00)99624-7"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1089\/vbz.2009.0249"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1126\/science.3823909"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2010.09-0318"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.71.5.522"}],"container-title":["Onderstepoort J Vet Res"],"original-title":[],"link":[{"URL":"http:\/\/ojvr.org\/index.php\/ojvr\/article\/viewFile\/717\/975","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,1]],"date-time":"2017-06-01T11:18:20Z","timestamp":1496315900000},"score":1,"resource":{"primary":{"URL":"http:\/\/ojvr.org\/index.php\/ojvr\/article\/view\/717"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,4,23]]},"references-count":8,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2014,4,23]]}},"URL":"https:\/\/doi.org\/10.4102\/ojvr.v81i2.717","relation":{},"ISSN":["2219-0635","0030-2465"],"issn-type":[{"value":"2219-0635","type":"electronic"},{"value":"0030-2465","type":"print"}],"subject":[],"published":{"date-parts":[[2014,4,23]]}}}
