Given that the drop in malaria prevalence in Nigeria has been very modest in the last 5 years, it would be wise to take another look at the methods being used - which unfortunately are ephemeral (indoor sprays, bednets and drugs) and must be repeated every year. The lack of emphasis on permanent measures, such as Larval Source Management, is a key to the problem. With the ephemeral methods, because the national budget for malaria control can only increase slowly, thus the program will only increase slowly.
Larval Source Management
I am pleased to send you this brief summary of our most recent and interesting African Malaria Dialogue, held during a luncheon meeting on Wednesday 9 October at the Harvard School of Public Health in Boston.
I am a civil engineer with experience in drainage and flood control. Drainage and flood control infrastructure can be an important part of integrated pest management as a means for larval source management.
Unfortunately, the related drainage infrastructure for a diked area typically has a number of drawbacks: 1) during dry periods, the drainage system for the low-lying land protected by the dike will inevitably include areas of stagnant water; 2) the lowered water table will cause the land to subside - which will make gravity drainage more difficult and produce more stagnant water; and 3) wetland environments will be severely degraded, harming flora and fauna.
Diked areas adjacent to tidally-influence watercourses can use tidal water level variations to significantly reduce stagnant water in the drainage system; reduce subsidence; and enhance wetlands.
