Hypothesis
How does urbanization affect malaria prevalence in Dar es Salaam?
Conclusion
The number of clinical malaria cases was much lower than routine reporting suggested.
Supporting Evidence
- Only 5.2% of fever cases were positive for malaria.
- Malaria prevalence was low in school surveys, ranging from 0.8% to 3.7%.
- High coverage of insecticide-treated nets was associated with reduced malaria risk.
Takeaway
This study looked at how many people in Dar es Salaam have malaria. It found that fewer people have it than doctors thought.
Methodology
A rapid assessment of urban malaria was conducted using a standard RUMA methodology, including school parasitaemia surveys and health facility fever surveys.
Potential Biases
Potential over-reporting of malaria cases due to reliance on health facility data.
Limitations
The study was conducted during a dry season, which may not represent malaria prevalence during wetter periods.
Participant Demographics
Participants included schoolchildren aged 6-12 years and patients presenting with fever at health facilities.
