Bed nets used to protect against malaria do not last long in a semi-arid area of Ethiopia: A cohort study
Solomon, Tarekegn; Loha, Eskindir; Deressa, Wakgari; Balkew, Meshesha; Gari, Taye; Overgaard, Hans Jørgen; Lindtjorn, Bernt (Peer reviewed; Journal article, 2018-06-20)Background: Long-lasting insecticidal nets (LLINs) are a key tool for malaria prevention and control. Currently, the recommended serviceable life of an LLIN is 3 years under field conditions. However, field studies show ... -
Combining long-lasting insecticidal nets and indoor residual spraying for malaria prevention in Ethiopia: Study protocol for a cluster randomized controlled trial
Deressa, Wakgari; Loha, Eskindir; Balkew, Meshesha; Hailu, Alemayehu; Gari, Taye; Kenea, Oljira; Overgaard, Hans Jørgen; Gebremichael, Teshome; Robberstad, Bjarne; Lindtjørn, Bernt (Peer reviewed; Journal article, 2016-01-12)Background: Long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) are the main malaria prevention interventions in Ethiopia. There is conflicting evidence that the combined application of both interventions ... -
Comparison of two adult mosquito sampling methods with human landing catches in south-central Ethiopia
Kenea, Oljira; Balkew, Meshesha; Tekie, Habte; Gebre-Michael, Teshome; Deressa, Wakgari; Loha, Eskindir; Lindtjørn, Bernt; Overgaard, Hans Jørgen (Peer reviewed; Journal article, 2017-01-13)Background: The human landing catch (HLC) is the standard reference method for measuring human exposure to mosquito bites. However, HLC is labour-intensive, exposes collectors to infectious mosquito bites and is subjected ... -
Impact of combining indoor residual spraying and long-lasting insecticidal nets on Anopheles arabiensis in Ethiopia: Results from a cluster randomized controlled trial
Kenea, Oljira; Balkew, Meshesha; Tekie, Habte; Deressa, Wakgari; Loha, Eskindir; Lindtjorn, Bernt; Overgaard, Hans Jørgen (Peer reviewed; Journal article, 2019-05-24)Background: 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. ... -
Long-lasting insecticidal nets and indoor residual spraying may not be sufficient to eliminate malaria in a low malaria incidence area: Results from a cluster randomized controlled trial in Ethiopia
Loha, Eskindir; Deressa, Wakgari; Ayana, Taye Gari; Balkew, Meshesha; Kenea, Oljira; Shanka, Tarekegn Solomon; Hailu, Alemayehu; Robberstad, Bjarne; Roro, Meselech Assegid; Overgaard, Hans Jørgen; Lindtjorn, Bernt (Peer reviewed; Journal article, 2019-04-18)Background Conflicting results exist on the added benefit of combining long-lasting insecticidal nets (LLINs) with indoor residual spraying (IRS) to control malaria infection. The main study objective was to evaluate whether ... -
Low use of long-lasting insecticidal nets for malaria prevention in south-central Ethiopia: A community-based cohort study
Shanka, Tarekegn Solomon; Loha, Eskindir; Deressa, Wakgari; Gari, Taye; Overgaard, Hans Jørgen; Lindtjorn, Bernt (Peer reviewed; Journal article, 2019-01-10)Introduction: A decline in malaria morbidity and mortality has been documented in Ethiopia since 2005 following a scale-up of the distribution of long-lasting insecticidal nets (LLINs). However, universal access to LLINs ...
