Bottom Line: The campaign was not associated with any changes in child mortality.The most likely explanation is the high coverage of nets in the study area before the campaign which could have had an effect on mosquito vectors, limiting the campaign's impact.Abstract available from the publisher.

ABSTRACT

Objective: To investigate if the first national insecticide-treated bed-net campaign in Burkina Faso, done in 2010, was followed by a decrease in childhood malaria in a district with high baseline transmission of the disease.

Methods: We obtained data on the prevalence of Plasmodium falciparum parasitaemia in children aged 2 weeks to 36 months from malaria surveys in 2009 and 2011. We assessed morbidity in children younger than 5 years by comparing data from the Nouna health district's health management information system before and after the campaign in 2010. We analysed mortality data from 2008 to 2012 from Nouna's health and demographic surveillance system.

Findings: The bed-net campaign was associated with an increase in the reported use of insecticide-treated nets. In 2009, 73% (630/869) of children reportedly slept under nets. In 2011, 92% (449/487) did. The campaign had no effect on the proportion of young children with P. falciparum parasitaemia after the rainy season; 52% (442/858) in 2009 and 53% (263/499) in 2011. Cases of malaria increased markedly after the campaign, as did the number of children presenting with other diseases. The campaign was not associated with any changes in child mortality.

Conclusion: The 2010 insecticide-treated net campaign in Burkina Faso was not associated with a decrease in care-seeking for malaria or all-cause mortality in children younger than 5 years. The most likely explanation is the high coverage of nets in the study area before the campaign which could have had an effect on mosquito vectors, limiting the campaign's impact.

Mentions: Overall, there was a substantial decline in all-cause child mortality between 1993 and 2012,21,23 but there was no decrease in the period of interest between 2008 and 2012 (Fig. 3). Moreover, between 2008 and 2012 mortality showed a characteristic seasonal pattern, with no change in the pattern after the insecticide-treated net campaign (Fig. 4). During the period, mortality remained relatively constant in children aged 1 to 4 years but, in infants, there was a slight increasing trend between 2009 and 2012 (Fig. 5). Mortality was significantly lower in Nouna town than the rural neighbouring villages and after 2009 the rural area showed an increasing trend in mortality (Fig. 6).
