This report describes four cases of RVF in farm workers associated with an isolated outbreak on a sheep farm in the Free State Province of South Africa, in 2018. In contrast to the last major RVF epidemic in South Africa in 2010\u20132011, where detection of human cases served as an alert for an ongoing outbreak in livestock, the current isolated outbreak was first detected in livestock, and human cases recognized following subsequent epidemiological investigation. This highlights the importance of early recognition of livestock cases in reducing risk and impact of a subsequent RVF epidemic in humans. People working with animals should be aware of transmission routes and take precautions to minimize risk of infection.<\/jats:p>","DOI":"10.1089\/vbz.2018.2357","type":"journal-article","created":{"date-parts":[[2018,9,5]],"date-time":"2018-09-05T15:08:29Z","timestamp":1536160109000},"page":"713-715","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":30,"title":["Human Cases of Rift Valley Fever in South Africa, 2018"],"prefix":"10.1177","volume":"18","author":[{"given":"Petrus","family":"Jansen van Vuren","sequence":"first","affiliation":[{"name":"National Institute for Communicable Diseases","place":["South Africa"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joe","family":"Kgaladi","sequence":"additional","affiliation":[{"name":"National Institute for Communicable Diseases","place":["South Africa"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venessa","family":"Patharoo","sequence":"additional","affiliation":[{"name":"National Institute for Communicable Diseases","place":["South Africa"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phumza","family":"Ohaebosim","sequence":"additional","affiliation":[{"name":"National Institute for Communicable Diseases","place":["South Africa"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Veerle","family":"Msimang","sequence":"additional","affiliation":[{"name":"National Institute for Communicable Diseases","place":["South Africa"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Babsy","family":"Nyokong","sequence":"additional","affiliation":[{"name":"Free State Department of Health, Bloemfontein, South Africa."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janusz T.","family":"Paweska","sequence":"additional","affiliation":[{"name":"National Institute for Communicable Diseases","place":["South Africa"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,11,28]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid1912.121527"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.7196\/SAMJ.4544"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.40.7.2323-2330.2002"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00705-018-3843-5"},{"key":"e_1_3_3_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jviromet.2005.02.008"},{"key":"e_1_3_3_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jviromet.2004.11.020"},{"key":"e_1_3_3_8_1","doi-asserted-by":"publisher","DOI":"10.1051\/vetres\/2010033"},{"key":"e_1_3_3_9_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022172400065426"},{"key":"e_1_3_3_10_1","unstructured":"World Organization for Animal Health (OIE).
