The proportion of houses infested by vector mosquitoes correlated inversely with intensity of anti-mosquito interventions, and the vector population developed independently of rainfall. Local periods of drought promoted vector abundance in two ways: residents stored water in which vector mosquitoes could breed, and cholera outbreaks due to contaminated water diverted local health workers from routine anti-vector activities. One dengue outbreak became apparent to authorities more than two months after it commenced but would have been identified almost immediately had dengue-like disease in indicator hospitals been monitored. Active surveillance, therefore, offers a window of opportunity for promptly executed anti-dengue interventions. Source-reduction measures that suppress vector infestations to less than 1% of houses effectively avert outbreaks of dengue.<\/jats:p>","DOI":"10.4269\/ajtmh.2000.62.378","type":"journal-article","created":{"date-parts":[[2017,5,10]],"date-time":"2017-05-10T17:10:32Z","timestamp":1494436232000},"page":"378-383","source":"Crossref","is-referenced-by-count":120,"title":["Vector densities that potentiate dengue outbreaks in a Brazilian city."],"prefix":"10.4269","volume":"62","author":[{"given":"R J","family":"Pontes","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"Freeman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J W","family":"Oliveira-Lima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J C","family":"Hodgson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Spielman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","container-title":["The American journal of tropical medicine and hygiene"],"original-title":[],"link":[{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/62\/3\/article-p378.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/62\/3\/article-p378.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/62\/3\/article-p378.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,4]],"date-time":"2024-09-04T10:19:08Z","timestamp":1725445148000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/62\/3\/article-p378.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,3]]},"references-count":0,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.4269\/ajtmh.2000.62.378","relation":{},"ISSN":["0002-9637"],"issn-type":[{"value":"0002-9637","type":"print"}],"subject":[],"published":{"date-parts":[[2000,3]]}}}
