“…Likewise, our chosen SARIMA model correlates with a model in the study area (25). While previous studies have assessed the relationship between rainfall and malaria cases within specific localities and communities, employing survey and hospital data (28,29), the present findings using data from the DHIS2 presents a distinct contribution, offering valuable insights.…”

Background In order to combat malaria, numerous strategic initiatives have been deployed over the years, with the goal of eliminating the disease in Nigeria. Despite these efforts, malaria morbidity still persists across the nation, and is presently under control measures. Various factors, encompassing both climatic and non-climatic elements, significantly impact the dynamics of malaria transmission across the country. This study applied time series analysis methods to understand the relationship between climatic factors, particularly temperature and rainfall, and the occurrence of malaria in the Southwest area of Nigeria. Methods This study analysed monthly data on documented cases of uncomplicated malaria obtained from the District Health Information System version 2, overseen by the Federal Ministry of Health. Additionally, monthly rainfall and temperature data spanning from 2013 to 2021, acquired from the Nigeria Meteorological Agency, were analysed. The datasets used for analysis were accessed on June 7, 2022, for research purposes. We applied univariate time series models to analyse monthly data on average temperature, rainfall, and malaria cases. Subsequently, cross-correlation analyses were conducted to investigate the relationships between malaria case data and the corresponding rainfall and temperature patterns, following a pre-whitening process. Results The patterns of malaria transmission exhibit variability among the various states within the Southwest region of Nigeria from 2013 to 2021. On average, Oyo State consistently recorded relatively higher temperatures compared to its neighbouring states. Conversely, Ondo State receives a higher average monthly rainfall. This state, similar to others in the region, experiences two distinct wet seasons, each characterised by different peak periods. In terms of temporal relationships, it is predicted that rainfall precedes malaria cases by one month across all the states. However, with regard to temperature, the five other states (excluding Osun state) lead by two months. Conclusion The results of this study underscore the varied characteristics of malaria transmission patterns and climate change, even across the individual states within the Southwest region of the country. This recognition of variations in malaria transmission and climatic factors is valuable for policymakers as it enables them to strategically allocate and optimise the implementation of interventions at state-specific level, rather than at zonal level. These interventions might involve distributing and advocating for the use of insecticide-treated bed nets, indoor residual spraying, and seasonal malaria chemoprevention tailored to the unique requirements and circumstances at the state level.

The climate-health nexus is well documented in the field of biometeorology. Since its inception, Biometeorology has in many ways become the umbrella under which much of this collaborative research has been conducted. Whilst a range of review papers have considered the development of biometeorological research and its coverage in this journal, and a few have reviewed the literature on specific diseases, none have focused on the sub-field of climate and health as a whole. Since its first issue in 1957, the International Journal of Biometeorology has published a total of 2183 papers that broadly consider human health and its relationship with climate. In this review, we identify a total of 180 (8.3%, n = 2183) of these papers that specifically focus on the intersection between meteorological variables and specific, named diagnosable diseases, and explore the publication trends thereof. The number of publications on climate and health in the journal increases considerably since 2011. The largest number of publications on the topic was in 2017 (18) followed by 2021 (17). Of the 180 studies conducted, respiratory diseases accounted for 37.2% of the publications, cardiovascular disease 17%, and cerebrovascular disease 11.1%. The literature on climate and health in the journal is dominated by studies from the global North, with a particular focus on Asia and Europe. Only 2.2% and 8.3% of these studies explore empirical evidence from the African continent and South America respectively. These findings highlight the importance of continued research on climate and human health, especially in low- and lower-middle-income countries, the populations of which are more vulnerable to climate-sensitive illnesses.
