Abstract
Introduction. Dengue Fever, Malaria, and Chikungunya persist as alarming global health threats. This paper aims to examines Dengue Fever, Malaria, and Chikungunya before and during the COVID-19 Pandemic in Indonesia for understanding epidemiological trends and developing evidence-based strategies of climate change impact.
Materials and methods. Data were collected since 2017-2022 from various sources, including national health surveys and meteorological agencies in Indonesia. Statistical analyses and correlations were conducted to understand the relationships between disease incidence, temperature, rainfall, and pandemic-related measures
Results. In Indonesia, Dengue fever incidence rose significantly from 26.1% in 2017 before the COVID-19 pandemic to 52.1% in 2022, malaria’s annual parasite incidence (API) increase by 0.6, from 1.0 per 1,000 population in 2017 to 1.6 in 2022 during the pandemic. Chikungunya cases surged by 23,6 times, increasing from 126 cases in 2017 to 2974 cases in 2022 From 2017 to 2019, temperature and rainfall showed a decreasing trend. However, between 2020 and 2022, both indicators fluctuated, with a notable spike in 2022 where rainfall reached 550 mm and temperatures increased by 1°C compared to previous years. An anomaly occurred in 2019 when both temperature and rainfall decreased, yet Dengue Fever Malaria, and Chikungunya cases increased.
Limitations. One limitation of this study is the potential for incomplete or inconsistent data reporting during the COVID-19 pandemic due to total lockdowns in Indonesia, which may affect the accuracy of the observed epidemiological trends.
Conclusion. Dengue Fever cases rose, possibly due to increased exposure at home. Malaria displayed a fluctuating trend, initially decreasing due to travel restrictions and possibly reduced testing coverage, then experiencing a rebound post-pandemic. Chikungunya’s surge during the pandemic and subsequent fluctuations underlines the need for ongoing disease surveillance. The correlation with environmental factors like temperature and rainfall underscores climate’s role in disease prevalence.
