Generalized additive mixed models (GAMMs) were used to explore the relationship between malaria cases and temperature and precipitation, with Poisson, zero-inflated Poisson and negative binomial distribution\u00a0and a logarithmic link function. The cross-correlation function assessed the time lags with peak correlations between malaria incidence, precipitation and temperature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The data showed 673 positive malaria incident cases amongst children in Kisumu compared to 1209 cases in Ukunda. The results indicate a positive correlation of malaria incidence with rainfall and temperature in Kisumu and a positive correlation between malaria incidence and rainfall and a negative correlation between malaria incidence and temperature in Ukunda. The lags between malaria incidence and rainfall were similar for Kisumu and Ukunda and estimated between 7 and 15\u00a0weeks.\u00a0With a time lag of 15\u00a0weeks in Ukunda, GAMM depicted a steady relationship between rainfall and malaria cases until rainfall reaches 150\u00a0mm and the relationship between malaria cases and temperature peaks at 26\u201327\u00a0\u00b0C. In Kisumu using a time lag of 15\u00a0weeks in the GAMM, a steady relationship between rainfall and malaria cases was observed until almost 120\u00a0mm of rainfall, peaking at 160\u00a0mm of rainfall and the relationship between malaria cases and temperature remained steady between 22 and 30\u00a0\u00b0C.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Assessing the changes in malaria case incidence due to changing seasonality and weather patterns provides policymakers with updated information to strategize malaria control policies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12936-025-05428-0","type":"journal-article","created":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T09:36:13Z","timestamp":1751362573000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Modelling the effects of precipitation and temperature on malaria incidence in coastal and western Kenya"],"prefix":"10.1186","volume":"24","author":[{"given":"Amna","family":"Tariq","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donal","family":"Bisanzio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis","family":"Mutuku","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryson","family":"Ndenga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zainab","family":"Jembe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priscilla","family":"Maina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip","family":"Chebii","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Ronga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria","family":"Okuta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
