This study evaluated the impact of climate and seasonal trends on malaria incidence in Dar es Salaam, Tanzania (2014\u20132024). Monthly cases and meteorological data were analyzed using seasonal-trend decomposition (STL) and generalized additive models (GAMs) to quantify nonlinear and lagged climatic associations. Over the decade, malaria incidence declined sharply from &gt;130 cases per 10,000 in 2014 to &lt;30 by 2023. However, strong seasonal peaks persisted, with STL revealing consistent annual surges during April\u2013June following the rainy season. GAM analysis identified rainfall as the dominant climatic driver, demonstrating significant 1- and 2-month lagged effects (p &lt; 0.001). Daytime (1-month lag) and night-time (2-month lag) temperatures showed non-linear associations, peaking in incidence at optimal mosquito-development temperatures (~30\u201331\u00b0C). Despite substantial incidence declines, transmission remains highly climate-sensitive. Driven primarily by lagged rainfall and temperature effects rather than current-month conditions, these dynamics underscore the urgent need for climate-informed early warning systems and targeted seasonal interventions in coastal urban environments.<\/jats:p>","DOI":"10.1017\/s095026882610185x","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T07:13:47Z","timestamp":1782198827000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Influence of climate variability and seasonal trends on malaria incidence in Dar es Salaam, Tanzania using generalized additive models"],"prefix":"10.1017","volume":"154","author":[{"given":"Iddi","family":"Mapande","sequence":"first","affiliation":[{"name":"Muhimbili University of Health and Allied Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-6743-8479","authenticated-orcid":false,"given":"January G.","family":"Msemakweli","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00za53h95","id-type":"ROR","asserted-by":"publisher"}],"name":"Johns Hopkins Bloomberg School of Public Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine C.","family":"Lan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00za53h95","id-type":"ROR","asserted-by":"publisher"}],"name":"Johns Hopkins Bloomberg School of Public Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor","family":"Okpanachi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03m2x1q45","id-type":"ROR","asserted-by":"publisher"}],"name":"The University of Arizona Mel and Enid Zuckerman College of Public Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hussein","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Muhimbili University of Health and Allied Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajendra P.","family":"Shrestha","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0403qcr87","id-type":"ROR","asserted-by":"publisher"}],"name":"Asian Institute of Technology School of Environment Resources and Development"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,6,23]]},"container-title":["Epidemiology and Infection"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S095026882610185X","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T05:44:06Z","timestamp":1783575846000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S095026882610185X\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"alternative-id":["S095026882610185X"],"URL":"https:\/\/doi.org\/10.1017\/s095026882610185x","relation":{},"ISSN":["0950-2688","1469-4409"],"issn-type":[{"value":"0950-2688","type":"print"},{"value":"1469-4409","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]},"assertion":[{"value":"\u00a9 The Author(s), 2026.
