Killing adult mosquitoes can reduce the proportion of old mosquitoes and have a significant impact on malaria transmission; The effectiveness of vector control can be compared using sporozoite rates and human biting rates; Human biting rates provide more useful information for planning, monitoring and evaluating vector control.
In vector control, it is widely accepted that killing adult mosquitoes would sharply reduce the proportion of old mosquitoes and cause the greatest changes to malaria transmission. The principle is based on a mathematical model of the sporozoite rate (the proportion of infective mosquitoes) that emphasized changes in mosquito age. Killing adult mosquitoes also reduces mosquito population densities, which are directly proportional to human biting rates (the number of bites, per person, per day). Eect sizes of vector control can be compared using sporozoite rates and human biting rates, which are commonly measured. We argue that human biting rates convey more use- ful information for planning, monitoring and evaluating vector control, and operational research should focus on understanding mosquito ecology.

Indirect effects of the COVID-19 pandemic on malaria intervention coverage, morbidity, and mortality in Africa: a geospatial modelling analysis

Daniel J. Weiss, Amelia Bertozzi-Villa, Susan F. Rumisha, Punam Amratia, Rohan Arambepola, Katherine E. Battle, Ewan Cameron, Elisabeth Chestnutt, Harry S. Gibson, Joseph Harris, Suzanne Keddie, Justin J. Millar, Jennifer Rozier, Tasmin L. Symons, Camilo Vargas-Ruiz, Simon I. Hay, David L. Smith, Pedro L. Alonso, Abdisalan M. Noor, Samir Bhatt, Peter W. Gething

Summary: This study evaluated the impact of disruptions to malaria control on malaria incidence and mortality in Africa. Findings show that reductions in access to effective antimalarial drug treatment and insecticide-treated net coverage could lead to increased malaria burden, potentially doubling malaria mortality in 2020.

Recommendations for building out mosquito-transmitted diseases in sub-Saharan Africa: the DELIVER mnemonic

Steven W. Lindsay, Michael Davies, Graham Alabaster, Hector Altamirano, Ebrima Jatta, Musa Jawara, Majo Carrasco-Tenezaca, Lorenz von Seidlein, Fiona C. Shenton, Lucy S. Tusting, Anne L. Wilson, Jakob Knudsen

Summary: The transmission of mosquito-borne diseases in sub-Saharan Africa mainly occurs within or around houses. By implementing simple changes to the built environment, such as screening doors and windows, closing eaves, using insecticide-treated nets, and maintaining environmental cleanliness, the risk of exposure to these diseases can be greatly reduced. The DELIVER package provides a combination of interventions to effectively combat mosquito-transmitted diseases and prevent their re-emergence after elimination.

Within-household clustering of genetically related Plasmodium falciparum infections in a moderate transmission area of Uganda

Summary: Genetic diversity of malaria parasites was high in a moderate transmission area, but fine-scale population structure and spatial clustering of related infections were detectable. Even in areas with relatively low differences in malaria incidence, genetic data revealed differences in multiplicity of infection and relatedness patterns within households.

Impact of seasonality and malaria control interventions on Anopheles density and species composition from three areas of Uganda with differing malaria endemicity

Henry Ddumba Mawejje, Maxwell Kilama, Simon P. Kigozi, Alex K. Musiime, Moses Kamya, Jo Lines, Steven W. Lindsay, David Smith, Grant Dorsey, Martin J. Donnelly, Sarah G. Staedke

Summary: This study in Uganda found that LLINs and IRS had differential impacts on Anopheles species composition and density in areas with different transmission intensities. The combination of LLINs and multiple rounds of IRS in high transmission areas nearly eliminated An. gambiae s.s. and An. funestus s.l., leading to a shift in predominant vector species. Developing interventions targeted at outdoor biting remains a priority for malaria control efforts.

Infection age as a predictor of epidemiological metrics for malaria

John M. Henry, Austin Carter, David L. Smith

Summary: Accurate estimation of the burden of malaria is crucial for strategic planning. This study reexamined historic data and found that infection age can be used as a predictor for malaria patterns. The predicted data based on infection age showed good agreement with the actual data. This research provides a new method for predicting malaria-related indicators.

Current dichotomous metrics obscure trends in severe and extreme child growth failure

Summary: The traditional thresholding approach fails to comprehensively assess child growth failure and obscures trends in populations with the highest rates of CGF. Our analysis presents the first ever estimates of complete distributions of child growth for different age groups and sexes, revealing hidden trends.

Pre-existing partner-drug resistance to artemisinin combination therapies facilitates the emergence and spread of artemisinin resistance: a consensus modelling study

Oliver J. Watson, Bo Gao, Tran Dang Nguyen, Thu Nguyen-Anh Tran, Melissa A. Penny, David L. Smith, Lucy Okell, Ricardo Aguas, Maciej F. Boni

Summary: This study evaluated the impact of high levels of partner-drug resistance on the early emergence of artemisinin-resistant genotypes, finding that higher frequencies of pre-existing partner-drug resistance genotypes lead to earlier establishment of artemisinin resistance. It highlights the importance of continued investment in molecular surveillance of partner-drug resistant genotypes to guide the choice of first-line ACTs.

Simulating the Impacts of Augmenting Intensive Vector Control with Mass Drug Administration or Test-and-Treat Strategies on the Malaria Infectious Reservoir

Joaniter I. Nankabirwa, Emmanuel Arinaitwe, Jessica Briggs, John Rek, Philip J. Rosenthal, Moses R. Kamya, Peter Olwoch, David L. Smith, Isabel Rodriguez-Barraquer, Grant Dorsey, Bryan Greenhouse

Summary: Highly effective vector control can significantly reduce malaria burden, but individuals with parasitemia may contribute to onward transmission. A simulation based on data from Tororo District, Uganda, showed that mass drug administration (MDA) and test-and-treat interventions can accelerate decline in parasite prevalence. However, sustained benefits require repeated interventions or additional measures.

Summary: The Program for Resistance, Immunology, Surveillance, and Modeling of Malaria (PRISM) has conducted malaria research in Uganda since 2010, providing key findings on the malaria burden and opportunities for improved control and elimination. Key findings include the significant impact of combined distribution of long-lasting insecticidal-treated nets (LLINs) and indoor residual spraying (IRS) on reducing malaria burden, the importance of submicroscopic infections in malaria transmission, changing markers of drug resistance, and high levels of insecticide resistance.

How long is the last mile? Evaluating successful malaria elimination trajectories

Justin M. Cohen, Deepika Kandula, David L. Smith, Arnaud Le Menach

Summary: This investigation examines historical data to assess the timelines for achieving malaria elimination based on successful elimination programs in various countries. The study finds that the median timeline from the start of elimination efforts to the year with zero local cases is 12 years, with a median decline rate of 54% per year. It also identifies certain territory characteristics that are associated with faster elimination. These findings can help countries set feasible milestones towards malaria elimination.

Spatial dynamics of malaria transmission

Sean L. Wu, John M. Henry, Daniel T. Citron, Doreen Mbabazi Ssebuliba, Juliet Nakakawa Nsumba, C. Hector M. Sanchez, Oliver J. Brady, Carlos A. Guerra, Guillermo A. Garcia, Austin R. Carter, Heather M. Ferguson, Bakare Emmanuel Afolabi, Simon Hay, Robert C. Reiner Jr, Samson Kiware, David L. Smith

Summary: This article introduces a patch-based differential equation modeling framework for malaria transmission dynamics. The framework extends the Ross-Macdonald model and allows for planning, monitoring, and evaluation of malaria control. New algorithms are presented to simulate mosquito demography, dispersal, and egg laying, as well as parasite dispersal and spatial dynamics. The framework can be applied to other mosquito-borne pathogens.
