Knowing the factors in the urban environment underlying high <jats:italic>Ae<\/jats:italic>. <jats:italic>aegypti<\/jats:italic> abundance could guide intervention efforts to reduce <jats:italic>Ae<\/jats:italic>. <jats:italic>aegypti<\/jats:italic> breeding and the incidence of dengue. In this study, objective data on <jats:italic>Ae<\/jats:italic>. <jats:italic>aegypti<\/jats:italic> abundance in public apartment blocks estimated by Singapore\u2019s nationally representative Gravitrap surveillance system was obtained from the National Environmental Agency. Low and high abundance status public apartment blocks were classified based on the Gravitrap <jats:italic>Aegypti<\/jats:italic> Index, corresponding to the lowest and highest quartiles respectively. An environmental case-control study was conducted, wherein a blinded assessment of urban features hypothesised to form breeding habitats was conducted in 50 randomly sampled public apartment blocks with low and high abundance statuses each. Logistic regression was performed to identify features that correlated with abundance status. A multivariable logistic model was created to determine key urban features found in corridors and void decks which were predictive of the <jats:italic>Ae<\/jats:italic>. <jats:italic>aegypti<\/jats:italic> abundance status of the public apartment block. At a statistical level of significance of 0.20, the presence of gully traps [Odds Ratio (OR): 1.34, 95% Confidence Interval (CI): 1.10, 1.66], age of the public apartment block [OR: 2.23, 95% CI: 1.48, 3.60], housing price [OR: 0.33, 95% CI: 0.16, 0.61] and corridor cleanliness [OR: 0.67, 95% CI: 0.40, 1.07] were identified as important predictors of abundance status. To reduce <jats:italic>Ae<\/jats:italic>. <jats:italic>aegypti<\/jats:italic> abundance around public apartment blocks and potential onward dengue transmission, gully traps could be remodelled or replaced by other drainage types. Routine inspections of <jats:italic>Ae<\/jats:italic>. <jats:italic>aegypti<\/jats:italic> breeding should be targeted at older and low-income neighbourhoods. Campaigns for cleaner corridors should be promoted.<\/jats:p>","DOI":"10.1371\/journal.pntd.0011075","type":"journal-article","created":{"date-parts":[[2023,2,2]],"date-time":"2023-02-02T19:40:31Z","timestamp":1675366831000},"page":"e0011075","update-policy":"https:\/\/doi.org\/10.1371\/journal.pntd.corrections_policy","source":"Crossref","is-referenced-by-count":19,"title":["Features of the urban environment associated with Aedes aegypti abundance in high-rise public apartments in Singapore: An environmental case-control study"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1878-9946","authenticated-orcid":true,"given":"Stephanie A.","family":"Fernandez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyang","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Borame L.","family":"Dickens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lee Ching","family":"Ng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alex R.","family":"Cook","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jue Tao","family":"Lim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,2,2]]},"reference":[{"issue":"1","key":"pntd.0011075.ref001","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1093\/jme\/tjy154","article-title":"Mosquitoes (Diptera: Culicidae) of Singapore: Updated Checklist and New Records.","volume":"56","author":"SG Lam-Phua","year":"2019","journal-title":"J Med Entomol"},{"key":"pntd.0011075.ref002","unstructured":"Ministry of Health Singapore.
