Abstract Malaria is a serious global health issue, with around 200 million cases per year. As such, great effort has been put into the mass distribution of bed nets as a means of prophylaxis within Africa. Distributed mosquito nets are intended to be used for malaria protection, yet increasing evidence suggests that fishing is a primary use for these nets, providing fresh concerns for already stressed coastal ecosystems. While research documents the scale of mosquito net fisheries globally, no quantitative analysis of their landings exists. The effects of these fisheries on the wider ecosystem assemblages have not previously been examined. In this study, we present the first detailed analysis of the sustainability of these fisheries by examining the diversity, age class, trophic structure and magnitude of biomass removal. Dragnet landings, one of two gear types in which mosquito nets can be utilised, were recorded across ten sites in northern Mozambique where the use of Mosquito nets for fishing is common. Our results indicate a substantial removal of juveniles from coastal seagrass meadows, many of which are commercially important in the region or play important ecological roles. We conclude that the use of mosquito nets for fishing may contribute to food insecurity, greater poverty and the loss of ecosystem functioning.

Abstract Background: Malaria remains the world’s leading vector-born cause of mortality and morbidity, and Eastern Uganda contains some of the country’s highest prevalence rates. Though academic societies, such as universities, may be prone to high malaria transmission, the extent of the burden and risk factors in university communities of Eastern Uganda are poorly understood. The aim in this study was to examine malaria prevalence, preventive strategies, and risk factors, among University communities in Eastern Uganda; to inform targeted malaria eradication efforts in academic settings. Methods: A mixed methods approach was applied. A case study of Islamic University in Uganda (IUIU), located in Eastern Uganda, was selected. A retrospective approach was used to determine malaria prevalence in IUIU from August to December 2019. Stratified random sampling was used to select IUIU community members; these were subjected to semi-structured questionnaires and Key informant Interviews (KII) to examine the preventive approaches and risk factors. An observational survey was also conducted to identify barriers to malaria prevention. Data was analyzed using descriptive statistics, graphs, Chi-square, and pictures; with STATA version-15.0. Results: The study involved 255 respondents (204, 80% students, 51, 20% staff); 130, 51% were males, 125, 49% were females. Malaria prevalence was; 12.9%, 11.7% and 12.7% for students, staff, and the general study population respectively. Lowest prevalence was registered in November (8.3% for students, 0% for staff), and the highest in December (18.4% for students, 6.7% for staff). Overall malaria prevalence in IUIU was significantly greater than Uganda’s national prevalence (χ2=182.009; p<0.0001; 95%CI). The commonest intervention was, sleeping under insecticide-treated mosquito-nets (96%), and the rarest was usage of medicinal herbs (15%). Though 41 (17.5%) of respondents who used mosquito-nets never suffered malaria, usage of mosquito-nets was not significantly associated with absence of malaria infection (p = 0.83). The same applied for other interventions except timely testing and treatment (p = 0.02). Most frequently mentioned risk factors were; improper use of mosquito nets (214, 84%), inappropriate depositing of garbage (196, 77%), and “staying out late” (133, 52%). Key barriers to malaria prevention observed were; usage of damaged bed nets (38, 19% of 198), clogged trenches with liquid wastes, and perforated wire meshes in ventilators. Conclusion: The overall prevalence of malaria in IUIU community was 12.7%; and was significantly higher than Uganda’s national prevalence (7%). Usage of insecticide-treated bed-nets was the commonest intervention, but showed no statistically significant association with malaria non-prevalence. Awareness programs should be enhanced to address inappropriate use of malaria control methods/tools, because the widespread adoption of these interventions alone did not effectively curb the burden.

Background. Congenital malaria is a serious and common infection in tropical Africa. It has multiple consequences on the newborn and the mother. Objective. The objective of this study is to calculate the prevalence of congenital malaria, describe its clinical signs, and analyze its associated factors. Methodology. It is a cross-sectional and prospective study, conducted at Issaka Gazobi Maternity of Niamey, from June 1 to November 30, 2017. The diagnosis was made by microscopy of a thick and thin blood smear of mother, newborn, and umbilical cord. Results. Two hundred and forty-nine (249) consecutive newborn/mother pairs were included. The prevalence of congenital malaria infection was 26.51% (66/249) with a parasite density of 101 P/μl (SD: 47.3; [80; 320]). The prevalence of congenital malaria disease was 14.06% (35/249) with a parasite density of 108 P/μl (SD: 32.6; [40; 200]. All patients were infected with Plasmodium falciparum. 43% (18/35) of neonates had hyperthermia and did not have a sucking reflex, 8.5% (3/35) were anaemic, 11.42% (4/35) had convulsed, 20% (7/35) had a coma, and 45.71% (16/35) had a low birth weight. No deaths were recorded, and only the nonuse of bed nets was significantly associated with congenital malaria ( p = 0.04 ). Conclusion. In Niger, one out of four newborns is infected with Plasmodium. Infection can progress to congenital malaria disease. The use of mosquito nets and intermittent preventive treatment would reduce the incidence of congenital malaria.

Malaria is still a health problem in Indonesia, particularly in Eastern part of Indonesia. The use of LLIN insecticide bed nets is one of the efforts to reduce the malaria morbidity rate by protecting human from malaria vector bites. The Anopheles flavirostris, Anopheles barbirostris, and Anopheles subpictus mosquitoes are three of the species reported as malaria vectors in West-Southeast Maluku Regency. The aim of this research was to detect the kdr gene in An. flavirostris, An. barbirostris, and An.subpictus mosquitoes collected from Alusi Kelaan village, West-Southeast Maluku Regency. The research was conducted at the Papua Biomedical Research and Development Center, in June 2016. A total of six An. flavirostris, 42 An. barbirostris, and 24 An. subpictus were pooled separately for genomic DNA extraction. The sample used was the An. flavirostris, An. barbirostris, and An. subpictus that survived after the impregnated paper test. The kdr gene detection was carried out using quantitative PCR (qPCR) focused on points V1010 and L1014. The results showed that there were no kdr mutant strains in the An. flavirostris, An. barbirostris, and An. subpictus. These results indicated that the sensitivity of pyrethroid insecticides contained in LLIN mosquito nets to An. flavirostris, An. barbirostris, and An. subpictus mosquitoes was not decreased in West Southeast Maluku Regency.

Purworejo is the endemic area of ​​malaria with the highest case increase occurring in 2015 amounted to 1411 cases. Appropriate control can be performed effectively based on vector bionomics. The aims of study were to determine species, behavior, resistance, and control methods of malaria vectors. Methods were larva andmosquitoes collection, breeding place of mosquitoes surveys, resistance of mosquito and evaluation of the effectiveness of vector control. The research was conducted in Sendangsari Village, Bener District, Purworejo Regency The result of the research showed that An. barbirostris sucked blood indoor, outdoor, and cage. An. balabacensis sucked blood indoor and cage. An. maculatus, An. aconitus, An. kochi, An. Indifinitus, and An. fagus were found to suck blood in the cage. An. maculatus showed resistance to insecticide permetrin 0,75% Indoor Residual spraying (IRS) and the use of insecticide treated bed nets were the vector control perfomed in the area of study. The breeding place of mosquito were in hole around unused fields and pond. Based on bioassay test, the effectiveness of IRS application for one months were not effectively kill An. maculatus while the use of mosquito nets for three months were still effectively kill An. maculatus.
