Cochrane database of systematic reviews (Online), 4 . High coverage rates (90%) were attained in the district. The evidence from randomized comparisons of IRS versus no IRS confirms that IRS reduces malaria incidence in unstable malaria settings, but randomized trial data from stable malaria settings is very limited. Tusting LS, Thwing J, Sinclair D, Fillinger U, Gimnig J, Bonner KE, Bottomley C, Lindsay SW. Cochrane Database Syst Rev. Clipboard, Search History, and several other advanced features are temporarily unavailable. IRS versus Insecticide Treated Nets (ITNs). It has been used widely in Asia, the Pacific and Latin America, while in Africa its use has been more limited to the margins of malaria distribution in southern Africa and … Two authors extracted data, assessed risk of bias and analysed the data. In the IRS group, malaria prevalence was slightly lower but this was not significant (PE 6%), but mean haemoglobin was higher (mean difference 0.85 g/dL).In one CBA trial in Nigeria, IRS showed protection against malaria prevalence during the wet season (PE 26%; 95% CI 20 to 32%) but not in the dry season (PE 6%; 95% CI -4 to 15%). The objective of this study was to estimate the effect of multiple IRS rounds on malaria incidence and hemoglobin levels in a cohort of children in rural southeastern Uganda. Overview. Indoor residual spraying of households with insecticide data came from a program implemented in northwest Tanzania from 2008 to 2012; all other data originated from the published literature. Indoor residual spraying for preventing malaria. Adding indoor residual spraying in communities using insecticide-treated nets for the prevention of malaria, Electronic mosquito repellents for preventing mosquito bites and malaria infection, Mosquito repellents for malaria prevention, Insecticide-treated nets for preventing malaria, Mosquito larval source management for controlling malaria. Myers-Hansen JL, Abuaku B, Oyebola MK, Mensah BA, Ahorlu C, Wilson MD, Awandare G, Koram KA, Ngwa AA, Ghansah A. PLoS One. When comparing parasitological re-infection by active surveillance after treatment in short-term cohorts, ITNs appeared better, but it was likely not to be significant as the unadjusted CIs approached 1 (risk ratio IRS:ITN = 1.22). Some limited data suggest that ITN give better protection than IRS in unstable areas, but more trials are needed to compare the effects of ITNs with IRS, as well as to quantify their combined effects. Efficacy of insecticides used in indoor residual spraying for malaria control: an experimental trial on various surfaces in a “test house” Abstract. For ITNs, the World Health Organization (WHO) only recommended pyrethroids until 2018, but mosquito vectors are becoming resistant to this insecticide. Another successful method of mosquito control relies on the use of physical barriers such as bednets or curtains that can also be sprayed with insecticides (insecticide treated nets; ITN). Art. Two authors independently reviewed trials for inclusion. It is critical for the reduction and, ultimately, for the interruption of malaria transmission. Indoor residual spraying (IRS) is considered a valuable transmission control measure against malaria but exact efficacy data are not available for many epidemiological settings. Indoor residual spraying or IRS is the process of spraying the inside of dwellings with an insecticide to kill mosquitoes that spread malaria.A dilute solution of insecticide is sprayed on the inside walls of certain types of dwellings—those with walls made from porous materials such as mud or wood but not plaster as in city dwellings. Historically, IRS has reduced malaria transmission in many settings in the world, but the health effects of IRS have never been properly quantified. The insecticide lasts for at least four months, killing mosquitoes that land on them. The evidence from randomized comparisons of IRS versus no IRS confirms that IRS reduces malaria incidence in unstable malaria settings, but randomized trial data from stable malaria settings is very limited. IRS kills mosquitoes when they come in contact with treated surfaces, preventing disease transmission. Where possible, we adjusted confidence intervals (CIs) for clustering. 2018 Nov 6;11(11):CD000363. It involves spraying the inside of housing structures with an insecticide with a long residual activity, typically once or twice per year. No difference was found for malaria prevalence or haemoglobin.Unstable malaria (EIR < 1): Two studies; for incidence and prevalence, the malaria rates were higher in the IRS group compared to the ITN group in one study. Use of indoor residual spraying for scaling up global malaria control and elimination Indoor residual spraying (IRS) is one of the primary vector control interventions for … West PA, Protopopoff N, Wright A, Kivaju Z, Tigererwa R, Mosha FW, Kisinza W, Rowland M, Kleinschmidt I. PLoS Med. Malaria is a public health problem in the Brazilian Amazon region. insecticide-treated bed nets (ITNs), indoor residual spraying, and prevention of malaria in pregnancy. For malaria prevalence, ITNs appeared to give better protection against any infection compared to IRS in India (risk ratio IRS:ITN = 1.70) and also for both P. falciparum (risk ratio IRS:ITN = 1.78) and P. vivax (risk ratio IRS:ITN = 1.37). “The indoor residual spraying of insecticide to keep mosquitos out of homes is one of the key strategies we use to control malaria.” This year’s IRS campaign is the latest in a series of combined efforts between the U.S. Government and Madagascar’s Government to protect the Malagasy people from malaria. ) for clustering critical for the reduction and, ultimately, for the interruption of transmission.
