[Malaria in 2022: clinical and therapeutic aspects].

In 2022 as in 1884, the clinical presentation of uncomplicated malaria is unspecific: fever of variable intensity, continuous or rhythmic, chills, flu syndrome, headache, respiratory and digestive disorders. At any time, it can evolve into a severe form (ex-pernicious attack or cerebral malaria) or even lethal. By reading again Alphonse Laveran's book on malarial fevers, we realized to what extent the observations made at that time allowed for a methodical and orderly description of the clinical forms of malaria, very close to what we can still observe today. No symptom or sign is pathognomonic of the disease. Only the detection of plasmodia or "malaria microbes" by direct or immuno-chromatographic methods allows for diagnostic confirmation, which is a prerequisite for the implementation of a curative treatment.Serendipity, synthetic chemistry and traditional medicine are the three methods that led to the discovery and large-scale production of antimalarial drugs. Serendipity for quinine, synthetic chemistry for chloroquine, and research conducted around traditional Chinese medicine for artemisinin and its derivatives. The latter have marked a real revolution in the management of malaria, both in its uncomplicated and severe forms. However, as with other antimalarial drugs, its medium- and long-term efficacy is compromised by the emergence and spread of resistance in malaria parasites, particularly P. falciparum. The control and eradication of malaria therefore require continued research in both prevention and therapy.The disease so well described by Alphonse Laveran has not yet said its last word….
