Malaria prevalence by gender across age groups

Comparative positive parasite ratios between demographic profiles

Key Findings (Age & Gender)

  • •The highest risk group is Males in the 12-16 Years age bracket, peaking at 10.1%.
  • •Overall, Males generally exhibit a higher average prevalence across all displayed groups.
  • •Discrepancies in gender prevalence point to behavioral risk factors or varying exposure levels.

Prevalence by Net Use

Key Findings (Net Use)

  • •The No Net Last Night group showed a higher prevalence of 9.8%.
  • •The lowest prevalence was 7.1% among the Slept Under Net group.
  • •Differences in net usage strongly correlate with the effectiveness of physical mosquito barriers in preventing infection.

Prevalence by Elevation

Key Findings (Elevation)

  • •The 750-1250m elevation zone peaked at 9.0% prevalence.
  • •The lowest prevalence was recorded in the Above 1750m zone at 1.5%.
  • •Lower elevations typically support more robust mosquito breeding ecosystems, correlating with higher localized transmission.

Distribution of Anemia Severity

By Malaria Test Results

Key Findings

  • •Severe anemia is observed in 1.5% of Malaria-Positive cases, compared to 1.6% in Negative cases.
  • •Among those testing positive for Malaria, the most common anemia state is Non-anemic (63.3%).
  • •This highlights the compounding effect of parasitic infections on hemoglobin depletion, emphasizing the need for concurrent iron or nutritional interventions in positive cohorts.
