Effectiveness of malaria control during changing climate conditions in Eritrea, 1998-2003.

摘要: Objective: To assess the effectiveness of impregnated mosquito nets, indoor residual spraying and larval control relative to impacts climate variability in decline malaria cases Eritrea. Methods: Monthly data on clinical by subzoba (district) three zobas (zones) Eritrea for 1998–2003 were used Poisson regression models determine whether there is statistical evidence reduction DDT, malathion, nets over period, while analysing effects satellite-derived variables same geographic areas. Results: Both (with DDT or malathion) independently significantly negatively associated with cases, as was one zoba. Malaria positively related differences current previous months’ vegetation (NDVI) anomalies. The relationship rainfall 2 3 months previously also significant, but direction effect varied Standardized coefficients indicated a greater zoba less intense transmission. Conclusion: results support view that both have been effective against malaria, area. Thus climate, not only explanation recent Eritrea. If appropriate approaches are used, routine surveillance from attending health facilities can be useful assessing programme success providing estimates individual measures. Effectiveness suitable use cost-effectiveness analysis obtained.
