Malaria Research and Control

This study aimed to evaluate the organization of malaria control actions in the Indigenous population of the municipality of São Gabriel da Cachoeira, Amazonas, AM, Brazil, from 2003 to 2007. This is an ecological study to evaluate the impact of control measures. Statistical analysis of the indicators revealed that the number of cases showed an increasing trend, with the highest numbers occurring in the rural areas. The same trend was observed for the Annual Parasite Index (API), however the highest APIs were found in the urban areas. The proportion of cases caused by Plasmodium falciparum showed a reduction. Hospitalization and mortality rates presented fluctuations and the fatality rate decreased. The findings indicate that control actions have proved partially effective and that they have provided a broader capacity to detect cases and to provide immediate treatment. Although the municipality still presents a high risk for transmission, the Pluriannual Plan in progress seems to have a good prognosis for the control of the disease, if maintained in a sustainable and permanent way.
