Major decline in malaria morbidity and mortality in the Union of Comoros between 2010 and 2014: The effect of a combination of prevention and control measures.

BACKGROUND: Malaria remains a public health challenge in sub-Saharan Africa. In response to this, many countries are working towards achieving the World Health Assembly and Roll Back Malaria Partnership target of a 75% decline in malaria incidence. OBJECTIVE: To assess trends in malaria morbidity and mortality in the three islands of the Comoros Archipelago from 2010 to 2014. METHODS: This was a retrospective study in which all confirmed malaria cases and deaths recorded between 2010 and 2014 were accessed from the national malaria control database. Trends and comparisons in malaria incidence and case fatality rates for all age groups, including under-5 children and pregnant women, were analysed using Microsoft Excel and SPSS version 16. RESULTS: A substantial decline in malaria incidence was observed for each island between 2010 and 2014; from 75.98 cases per 1 000 population in 2010 to 0.14 in 2014 in Moheli, 60.60 to 0.02 in Anjouan and 235.36 to 5.47 in Grand Comoro. Additionally, a general reduction in malaria case fatalities was observed. In Moheli, there were no case fatalities between 2010 and 2014, while there was a decline in the case fatality rate in Anjouan (from 1.20 fatalities per 1 000 cases to 0) and Grand Comoros (0.51 to 0). There were also significant differences (p<0.05) in malaria incidence and case fatalities between the three islands. A similar trend was observed for pregnant women and under-5 children. CONCLUSIONS: Our study indicates a significant decline in malaria morbidity and mortality in the islands of Moheli, Anjouan and Grand Comoro from 2010 to 2014. This considerable reduction is attributed to a combination of malaria prevention and control interventions implemented during the study period.

Mass Drug Administration of Artemisinin-piperaquine on High Malaria Epidemic Area.

Malaria is the one of major diseases which threatens people's life in Africa. Out of humanitarianism, Chinese scientists has contributed to research of Artemisinin and ACTS more than 30 years, China provides long-term antimalaria assistance to Africa and gain great achievements. In Moheli, the island of Comoros, the antimalaria group used a new strategy which universal medication and proactive intervention. They established not only an effective antimalaria system and reporting system but also a local antimalaria team. Furthermore, they enhanced publicity and put mass protection and treatment into effect. Finally, they achieved significant result. In order to apply those successful experience to other countries in Africa, this paper summed up those experience and inspirations.
