Malaria

Malaria is a disease caused by Plasmodium parasites. The parasites are spread to people through the bites of infected female Anopheles mosquitoes, called malaria vectors. There are five parasite species that cause malaria in humans, and two of these species (P. falciparum and P. vivax) pose the greatest threat. Malaria is a major disease burden in tropical low-income countries, especially in Sub-Saharan Africa. People with malaria often experience fever, chills, and flu-like illness. Left untreated, they may develop severe complications and die.

Over 200 of our Swiss TPH staff and students are particularly passionate about malaria in a broad range of fields. We conduct basic research on the biology of Plasmodium spp., including gene regulation and parasite-host interactions. We identify and test new diagnostics, drugs, immunotherapies and vaccines for malaria in collaboration with product development partnerships and the private sector. We study the malaria vector Anopheles spp. to develop new effective vector control tools and strategies. And then, we validate these interventions in large-scale implementation studies with partners in endemic countries.

We apply innovative approaches in computational sciences, statistics, and mathematical modelling to increase our understanding of the biology and transmission of malaria and the impact of interventions. Finally, we use the generated evidence and experience to support decision-makers in malaria endemic countries and globally in developing of novel interventions and implementing effective malaria control and elimination strategies. We provide this support as the designated WHO Collaborating Centre for Modelling, Monitoring and Training for Malaria Control and Elimination.

Key Facts About Malaria

Malaria is a Major Disease Burden

  • Malaria is a disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes.
  • In 2023, nearly half of the world's population was at risk of malaria. While sub-Saharan Africa carries a disproportionately high share of the global malaria burden, the WHO Regions of South-East Asia and Eastern Mediterranean, Western Pacific, and the Americas also report significant numbers of cases .
  • There were an estimated 263 million cases of malaria in 2023, and the estimated number of malaria deaths stood at 597 000. In 2023, the African Region was home to 94% and 95% of malaria cases and deaths, respectively.
  • Children under 5 years of age are most at risk of severe complications from malaria; in 2023, they accounted for nearly 76% of all malaria deaths in the WHO African Region. [WHO]

Achievements in Malaria Control

  • Many countries with a low burden of disease maintained effective malaria responses during the pandemic and continued their drive towards elimination.
  • Five of the 11 High Burden to High Impact countries showed a decline in deaths in 2021 compared to 2020: the Democratic Republic of the Congo, Ghana, India, Niger and the United Republic of Tanzania. However, their contribution to the malaria burden is still substantial.
  • Countries in the Greater Mekong subregion (GMS) continued to successfully battle antimalarial drug resistance through lowering the case burden of P. falciparum.

Next Targets

  • WHO has recently launched a number of strategies to help countries build a more resilient response to malaria:
    • Tackling antimalarial drug resistance in Africa
    • Stopping the spread of Anopheles stephensi in Africa
    • Responding to malaria in urban areas
    • Using data to drive impact
  • WHO increased the transparency, flexibility and access to its malaria recommendations to support malaria-endemic countries.
