Le paludisme aujourd'hui

Malaria, a parasitic disease the pathogen of which was discovered by Alphonse Laveran in 1880 in the blood of febrile patients, remains in 2022 the most frequent endemic disease in tropical and subtropical countries. In its latest “World Malaria Report” available in November 2021, the WHO deals in great detail with the data collected in the field in 2019-2020, their progression over the last 20 years, and the measures to be taken to try to better control this life-threatening endemic. The number of malaria cases is estimated at 232 million in 2019 in 87 endemic countries, down from 245 million in 2000. The WHO African Region alone accounts for 94% of cases and the most frequent and severe infections due to Plasmodium falciparum species. If children under the age of 5 are not treated promptly, they can die. Globally, the number of malaria deaths declined steadily over the period 2000-2019, from 897,000 in 2000 to 568,000 in 2019, with nearly 95% of deaths occurring in 31 countries, primarily in sub-Saharan Africa. In other WHO regions, including Southeast Asia, malaria deaths decreased by 74%, with 35,000 deaths in 2000 compared to 9,000 in 2019. Malaria can be controlled worldwide, and possibly eradicated, if public information campaigns are strengthened and sufficient funds are made available.
