“…This discovery is in line with the findings of a research conducted in Kenya's Kilifi District (Rakiya et al, 2012). Most pregnant women were comfortable in sleeping under ITNs, during rainy season, knowledge on the benefits of ITNs, warmth it generates during cold weather and being non allergic to the chemical were the motivating factors similar to the findings of (Kimbi, Nkesa, Ndamukong-nyanga et al, 2014; Allcock et al, 2018;Tijani, 2017). The implication is that, Kintampo and for that matter Ghana as a country is doing very well in the promotion of ITNs use among antenatal women seeking ANC services in the Kintampo municipality.…”

Malaria in pregnancy is of global health concern. Free distributions of Insect-Repellent Preserved Nets (IRPNs) are introduced in Ghana to protect everyone particularly pregnant women from mosquito bites. This study aims at assessing the barriers and motivators to insecticide bed net use during gestation in the Kintampo Municipality. This study employed a descriptive cross-sectional study that used a mixed methods approach to conduct the study. Multi stage sampling technique was used. Proportionate sampling was used to determine the number of respondents from each facility. Purposive sampling technique was used to select partners of ANC attendees for a focus group discussion. Data was analysed using Stata version 15 and N-Vivo 12. Data triangulation techniques were used to merge the two data sources. Test of association between independent variables and dependent variable (ITN use) was examined using Chi-square test and logistic regression models to determine the strength of the relations. A p-value of ≤0.05 was deemed to be statistically significant. Majority of pregnant women 71.4% sleep under treated insecticides net. Motivators for bed net use were to prevent mosquito bites 228 (83.2%) and to provide privacy 17 (6.2%). Barriers to bed net use were heat 59 (55.7%) and inconvenience in sleeping under the net 4 (3.8%). There is high rate of insect repellent pickled net use amongst antenatal women. Household arrangements as well as bed nets hanging challenges in the room are barriers to net use. Key words: Malaria, mosquito nets, usage, motivators, barriers and pregnancy.

“…One of the most effective methods of the malaria vector control in Cameroon is the use of mosquito bed nets and depending on whether it is a long-lasting insecticidal one, further increases the vector control chances. Several studies have highlighted the importance of increased mosquito net usage and LLITN and their role in reducing the incidence of malaria in SSA (38)(39)(40)(41)(42)(43)(44). In this study, most urban-city centers and rural clusters household settlements in the North region had at least one mosquito net whether or not it was a treated (> 50% ), while the West and East regions recorded a low coverage for the above ITNs coverage category.…”

Background Cameroon has witnessed a 131,000 increase in malaria cases, according to a recent report addressing the malaria burden and control strategies in endemic regions. Studies have illustrated the association between malaria cases and environmental factors in Cameroon but limited in addressing how these factors vary in space for timely interventions. Thus, we want to find the spatial variability between malaria hotspot cases and environmental predictors using Geographically weighted regression (GWR) spatial modelling technique. Methods The global Ordinary least squares(OLS) tool in the modelling spatial relationships tool in ArcGIS 10.3. was used to select candidate explanatory environmental variables for a properly specified GWR model. The local GWR model used the OLS candidate variables to examine, predict and explore the spatial variability between environmental factors and malaria hotspot cases generated from Getis-Ord Gi* statistical analysis. Spatial maps of mosquito bed net ownership and GWR outputs were also created for public health surveillance. Results The OLS candidate environmental variable coefficients were statistically significant for a properly specified GWR model (adjusted R2 = 22.3% and p < 0.01). The GWR model identified a strong association between malaria cases and rainfall, vegetation index, population density, and drought episodes in most hotspot areas and a weak correlation with aridity and proximity to water (adjusted R2= 24.3%). The mosquito bed nets analysis maps demonstrated an overall low coverage(<50%) of household ownership. Conclusion The generated GWR maps suggest that for policymakers to eliminate malaria in Cameroon by 2030, there should be the creation of outreach programs that will target malaria hotspots locations, intensify free insecticidal net distribution, allocate specific funding, establish vaccination campaigns and carry out further investigations in areas where the environmental variables showed strong spatial associations with malaria hotspot cases.

“…There is, therefore, an urgent need for an alternative class of insecticide that can be used with nets to reduce selection pressure on pyrethroids. In addition to ITNs, indoor residual spraying (IRS) is also used in vector control programs in Africa but its coverage is below 50% [ 8 , 45 ]. Vector control programs should increase the coverage of IRS with insecticides that do not belong to pyrethroids or organochlorine like DDT.…”

Arthropod-borne viruses (Arboviruses) replicate in vertebrates and invertebrates and are mainly transmitted by mosquitoes. Between 2000 and 2021, several arbovirus outbreaks were recorded in African countries, including dengue, yellow fever, Chikungunya, Zika, and O’nyong nyong. Most often, the causes and factors involved in these outbreaks are unknown. We aimed to understand current knowledge regarding factors responsible for the persistent transmission and emergence of mosquito-borne arboviruses in Africa and to identify critical research gaps important for preventing future outbreaks. We used a systematic literature review between 2020 and 2021, to show that the main identified factors favoring the arbovirus outbreak in Africa are low vaccination coverage, high density and diversity of competent mosquitoes, insecticide resistance of mosquito vectors, and a scarcity of data on arboviruses. Further studies on arboviruses may include studies of competence to viral strains and the susceptibility of mosquito vectors to insecticides. Because of the detrimental effects of insecticides on human health and the environment, viral paratransgenesis and other biological control methods should be explored as alternatives or as supplements to insecticides. Graphical abstract Illustration of factors identified for promoting the transmission of arbovirus in Africa. The main factors are the lack of drugs and vaccines, low coverage of vaccination when a vaccine exists, competence of mosquitoes to viruses, diversity and high density of vectors. Climate change, urbanization, deforestation and agricultural practices, lead to a richness and high density of vectors.
