==Early life and education==
Widal's most notable contribution to medicine was his development of the [[Widal test]], a diagnostic test for typhoid fever. This test, which detects the presence of antibodies against the causative agents of typhoid fever, Salmonella typhi, and Salmonella paratyphi, represented a breakthrough in the diagnosis of the disease. Prior to the development of the Widal test, diagnosing typhoid fever was challenging and often inaccurate.
