Abstract
Background: Epidemiological surveys in malaria-endemic regions with permanent transmission require a simple, rapid, and cost-effective method to evaluate parasitemia.
Objective: To develop and validate a method for measuring parasite density using micro-hematocrit red blood cell counts on smears.
Methods: Procedure: The parasite density was measured by counting the number of red blood cells in micro-hematocrit smears.
Microscopy: Parasitemia was assessed by reading 75 to 100 microscopic fields at 100x magnification.
Statistical Analysis: The formula for determining parasitemia was statistically justified and explained.
Results: Participants: 1,163 healthy individuals and 534 consultants were included.
Age Groups: Analysis was conducted across different age groups.
Thresholds for Harmful Parasitemia:
Children: Harmful parasitemia threshold ranged between 3,000 and 6,000 trophozoites per milliliter of blood.
Adults: Threshold was lower than 1,000 trophozoites per milliliter of blood.
Conclusion: The method developed for evaluating parasitemia is effective for epidemiological surveys in malaria-endemic regions. Maintaining the diagnosis of malaria at the established parasitemia thresholds is crucial to prevent morbidity.
