Babesiosis was originally reported by the Romanian scientist, Victor Babes, in 1888.^[1] The disease was investigated for its renown infection in domesticated animals and cattle. In 1957, the first human babesiosis infection was documented in a splenectomized, Yugoslavian patient. All patients observed with babesiosis had also undergone a splenectomy, it wasn’t until 1969 that the infection was observed within a normal patient.^[1]

• Babesiosis was first discovered as a hemolytic infection in 1888 by the Romanian scientist, Victor Babes.^[1]
• Two Americans, Fred Kilborne and Theobald Smith discovered Babesia as the parasitic infection responsible for Texas Cattle Fever.^[1]

• In 1957, a splenectomized human patient is reported to suffer from a hemolytic illness likened to that of babesiosis. Babesia is identified as the parasite responsible for infection. All other reported patients suffering from the illness had also undergone a splenectomy until 1969.^[1]
• In 1969, the first babesiosis infection within a normal human patient, without a splenectomy, was documented.
• In 2011, the Center for Disease Control and Prevention, listed babesiosis as a nationally notifiable condition.^[2]
