Linking Households with Sanitation Access to Dengue Trends in the Philippines
This plot explores the relationship between the yearly number of households with sanitation facilities and monthly dengue cases from 2019 to 2022, focusing on whether increased sanitation correlates with fewer dengue cases, and whether dengue case peaks shift over time. The blue line represents the number of households with sanitation facilities, showing a steady increase each year that reflects improvements in sanitation. The purple line tracks monthly dengue cases, with distinct peaks, especially in 2019, followed by a notable decline in subsequent years. This drop coincides with COVID-19 mobility restrictions and intensified community cleanup drives. Seasonal peaks emerge in January, July, and August. Despite the difference in time frames—monthly dengue data and yearly sanitation data—the plot suggests an inverse relationship, with higher sanitation levels possibly linked to fewer dengue cases. However, other factors may also influence these trends, and sanitation alone may not be the sole factor in controlling waterborne diseases like dengue.
