Background: Malaria remains a substantial concern in the realm of public health on a worldwide level. Using information from the global burden of disease (GBD) 2019 for 204 countries and territories between 1990 and 2019, we assessed the burden of malaria.
Methods: Data on malaria were derived from the GBD 2019 study between 1990 and 2019. We evaluated the number of incidence, deaths, disability-adjusted life years (DALYs), age-standardized incidence rates (ASIR), age-standardized mortality rates (ASMR), and age-standardized DALY rates (ASDR), examining them across variables such as age, year, gender, country, region, and socio-demographic index (SDI).
Results: The burden of malaria decreased globally between 1990 and 2019. There were 2313.57× 10⁵ incident cases and 6.43× 10⁵ deaths in 2019, contributing to 464.38× 10⁵ DALYs. Largest incident cases were observed in Western Sub-Saharan Africa [1151.72 (95% UI: 890.01– 1527.17)] × 10⁵ in 2019. The only region where deaths increased between 1990 and 2019 was Western Sub-Saharan Africa. ASRs of malaria are distributed heterogeneously in different regions. The highest ASIR was observed in Central Sub-Saharan Africa [21,557.65 (95% UI: 16,639.4– 27,491.48)] in 2019. From 1990 to 2019, the ASMR of malaria declined. Compared to other age cohorts, the ASIR, ASMR, and ASDR for children aged between 1 to 4 years were found to be higher. Worst-affected regions by malaria infection were the low-middle SDI region and low SDI region.
Conclusion: Malaria threatens global public health, especially in Central Sub-Saharan Africa and Western Sub-Saharan Africa. Children 1– 4 years old continue to bear the most significant burden of malaria. The study’s results will guide efforts to reduce malaria’s impact on the global population.
