Shoklo Malaria Research Unit – Mawker Thei Clinic on the banks of the Moi River. Zo Zo is 26 years old and was brought in my his father from a village across the river. The plasmodium parasites have impaired his liver function. His urine is full of blood. Margos, the young volunteer doctor from Holland who attends the man is relieved to find that the “blockage” was in the line and not in the patient, who needs to be transferred to the Mae Tao clinic for a blood transfusion. Zo Zo is unconscious. Without a blood transfusion he will probably die. Malaria is both preventable and treatable. Most of the people who make it across the river to the clinics, survive.
