How do I know that e.Histolatyca reached the bloodstream or the liver? How long does it take for it to travel from the large intestine to other organs

Variable. Most infected people, about 90%, are asymptomatic. In ~10% of invasive cases the amoebae enter the bloodstream and may travel to liver, causing an abscess, and other organs in the body. This can occur as early as 2-4 weeks after infected or months to years later. Symptoms can include fever, nausea, vomiting, and pain in the rt upper abdominal pain. Dx is by blood tests, ct scan, and needle biopsy.
