Indoor residual house spraying (IRS) and long-lasting insecticidal nets (LLINs) are the key front-line malaria vector interventions against Anopheles arabiensis, the sole primary malaria vector in Ethiopia. Universal coverage of both interventions has been promoted and there is a growing demand in combinations of interventions for malaria control and elimination. This study compared the impact on entomological outcomes of combining IRS and LLINs with either intervention alone in Adami Tullu district, south-central Ethiopia. The epidemiological outcomes were recently published on a separate paper.
long-lasting insecticidal nets (LLINs)
The clinical malaria incidence and anaemia prevalence were similar in the four study groups.
High ownership and retention of the LLINs was observed in the intervention group.
In Ruangwa, net care was defined as overall net maintenance, such as cleanliness, and not directly associated with the prevention of damage as reported in other studies.
While having saved many lives over the past decade, continued dependence on mass distribution of free long-lasting insecticidal nets (LLINs) is not sufficient and may not be sustainable.
The collaborative planning process and strong coordination of campaign actors allowed Mozambique’s NMCP and partners to successfully carry out the first countrywide LLINs UCC in the country.
The study showed that the median serviceable life of LLINs is only 12 months.
Free mass distribution of LLINs policy was adopted in 2005 in Zambia.
The finding of widespread resistance to permethrin in DRC is concerning and alternative insecticides should be evaluated.
Two years after the last mass campaign, the percentage of households or population with access to LLINs was low.
