New Case
Another case from Northern Tanzania, up by the border of Kenya. 32 yo pregnant woman admitted to the hospital, dehydrated, reporting 3+ weeks of diarrhea. Second trimester, second pregnancy, reports stools are sticky and it is hard to get herself clean. She also noticed blood mixed in the stool. No fever, no chills, but she feels weak. While many in the area get their water from boreholes, rivers and rainfall she reports getting hers from a nearby river. She lives with her husband and one child who is 2 years old. She is HIV negative and reports she had been in good health otherwise. She looked tired and worn down when she arrived in the hospital but is already feeling better. Her blood work is notable for a low hemoglobin and elevated creatinine. Stool studies are sent and Ockam would be confused but Dr Hickam would know what to do.
