Determining Effective Spraying Periods to Control Malaria via Indoor Residual Spraying in Sub-Saharan Africa [PDF]

Journal of Applied Mathematics and Decision Sciences, 2008
Indoor residual spraying—spraying insecticide inside houses to kill mosquitoes—is an important method for controlling malaria vectors in sub-Saharan Africa. We propose a mathematical model for both regular and non-fixed spraying, using impulsive differential equations. First, we determine the stability properties of the nonimpulsive system.

Effectiveness and cost-effectiveness of reactive, targeted indoor residual spraying for malaria control in low-transmission settings: a cluster-randomised, non-inferiority trial in South Africa

The Lancet, 2021
Summary Background Increasing insecticide costs and constrained malaria budgets could make universal vector control strategies, such as indoor residual spraying (IRS), unsustainable in low-transmission settings. We investigated the effectiveness and cost-

Comparison of Indoor Residual Spray Equipment for Malaria Control in Liberia

Journal of the American Mosquito Control Association, 2015
We describe and compare a new innovative backpack compressed-air sprayer (JQSX-12) to a Stihl® 450 backpack mist blower and a manually operated compression sprayer for its effectiveness as an alternative operational tool for indoor residual insecticide application to control malaria in Liberia.

The influence of the environment and indoor residual spraying on malaria risk in a cohort of children in Uganda

Scientific Reports, 2022
AbstractStudies have estimated the impact of the environment on malaria incidence although few have explored the differential impact due to malaria control interventions. Therefore, the objective of the study was to evaluate the effect of indoor residual spraying (IRS) on the relationship between malaria and environment (i.e.

Effectiveness of a national mass distribution campaign of long-lasting insecticide-treated nets and indoor residual spraying on clinical malaria in Malawi, 2018–2020

BMJ Global Health, 2021
Introduction Malawi’s malaria burden is primarily assessed via cross-sectional national household surveys. However, malaria is spatially and temporally heterogenous and no analyses have been performed at a subdistrict level throughout the course of a ...

Partial indoor residual spraying with pirimiphos-methyl as an effective and cost-saving measure for the control of Anopheles gambiae s.l. in northern Ghana

Scientific Reports, 2021
The scale up of indoor residual spraying (IRS) and insecticide treated nets have contributed significantly to global reductions in malaria prevalence over the last two decades. However, widespread pyrethroid resistance has necessitated the use of new and

Controlling malaria with indoor residual spraying in spatially heterogenous environments

Mathematical Biosciences and Engineering, 2011
Indoor residual spraying-spraying insecticide inside houses to kill mosquitoes-has been one of the most effective methods of disease control ever devised, being responsible for the near-eradication of malaria from the world in the third quarter of the twentieth century and saving tens of millions of lives.

Short persistence of bendiocarb sprayed on pervious walls and its implication for the indoor residual spray program in Ethiopia [PDF]

Parasites & Vectors, 2016
With the emergence and spread of vector resistance to pyrethroids and DDT in Africa, several countries have recently switched or are considering switching to carbamates and/or organophosphates for indoor residual spraying (IRS). However, data collected on the residual life of bendiocarb used for IRS in some areas indicate shorter than expected bio ...

Impact of indoor residual spray with synthetic pyrethroid in Gandhinagar district, Gujarat

Indian Journal of Community Medicine, 2009
Indoor residual spray (IRS), with appropriate insecticide, is an effective weapon for the control of malaria. Two rounds of indoor residual spray, with synthetic pyrethroid, are given in highly malaria endemic areas. It aims to prevent transmission of malaria by adult vector mosquitoes.To assess the impact of indoor residual spray in the highly malaria-
