Malaria remains a significant global public health burden, with an estimated 263 million cases and 597,000 deaths worldwide in 2023. The majority of this burden, approximately 94% of cases and 95% of deaths, occurred in Africa, where children under five and pregnant women are particularly vulnerable.

Tuberculosis killed 1.25 million people last year, making it the world’s leading cause of death from an infectious disease. But it receives only $5.7 billion of the $22 billion of funding needed.
