The number of\n                    <jats:italic>Ae. vexans<\/jats:italic>\n                    females (the predominant species during the 2002 rainy season) trapped per trap\u2010night was the dependent variable in statistical analyses. The trapping periods were divided into six series of two to five consecutive days, from July to November 2002. Three temporary ponds were selected according to their ecological features: depth, bank slope, size and vegetation cover. Traps were laid on the pond bank and in the nearest available compound, close to the sheep night pen. Data were analysed using mixed\u2010effects Poisson models. The explanatory variables were the trapping period, the pond, and the capture site.\n                  <\/jats:p>\n                  <jats:p>The exposure to mosquito bites varied according to the pond type, suggesting that the risk of transmission was spatially heterogeneous. However, there was no obvious trend in transmission risk due to the effect of the distance from the compound to the pond. The period with the highest exposure was in October, i.e. when transhumant herds left the Ferlo to relocate to their dry\u2010season settlement. It is thus hypothesized that transhumance, the seasonal movements of herds, plays a significant role in the dissemination of RVF virus in the region.<\/jats:p>","DOI":"10.1111\/j.0269-283x.2004.00511.x","type":"journal-article","created":{"date-parts":[[2004,9,2]],"date-time":"2004-09-02T16:06:25Z","timestamp":1094141185000},"page":"247-255","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Exposure of sheep to mosquito bites: possible consequences for the transmission risk of Rift Valley Fever in Senegal"],"prefix":"10.1111","volume":"18","author":[{"given":"V.","family":"Chevalier","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Mondet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Diaite","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Lancelot","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
