Natural History

Progression of a babesiosis infection may present itself in a variety of clinical manifestations. The severity of these clinical manifestations are potentially a direct reflection of blood parasitemia levels in the blood.

Asymptomatic

Early Stage

  • Chronic infection within asymptomatic populations remain within the incubation stage.

Late Stage

  • There are no further clinical manifestations

Further development if left untreated

  • Clinical manifestations may occur as an asymptomatic patient becomes immuno-compromised or naturally ages.

Symptomatic

Early Stage

  • Incubation period of 1-6 weeks, however may incubate as long as 3 months.
  • Clinical manifestations will present themselves as non-specific flu like symptoms.
  • Common symptoms will include fever, headache, muscle aches, and pain.
  • Severe illness may occur in older and immuno compromised populations. Severe illness will present itself as malaria-like.
  • Symptoms associated with a severe infection include nausea, emesis, night sweats, and anorexia.

Late Stage

  • Severe hemolysis may lead to jaundice.
  • Other complications include a Shock-like state, renal failure, and pulmonary edema.

Further development if left untreated

  • Heightened levels of parasitemia in blood.
  • Severe anemia, hemolysis, thrombocytopenia, leukopenia, and eventually death.

Complications

Babesiosis can be a very severe illness with complications including:[1]

  • Jaundice
  • Hemoglobinuria
