“…Moreover, 56.5% of households reported they use bed nets only during sleeping time. Considering that malaria transmission occurs during 10 months in the study area and some of malaria vectors prefer to bite mainly outdoors in the earlier times of night [ 4 , 12 , 31 ], peoples who spend earlier times of night outside may be bitten more frequently and have more chance to get malaria. There were several reports confirming that regular use of insecticide-treated nets increase when individuals receive information about bed nets [ 8 , 13 ].…”

“…Indoor residual spraying and distribution of long-lasting insecticide-treated nets have been the main vector control measures implemented as part of an integrated approach to malaria elimination in this county [ 12 ]. In addition to achieve sufficient LLINs coverage, a challenge is identifying and addressing the behavioural factors that influence LLINs use.…”

BackgroundSince malaria is one of the foremost public health problems in Iran, a malaria elimination phase has been initiated and application of long-lasting insecticidal nets (LLINs) is an important strategy for control. Success and effectiveness of this community based strategy largely dependent on proper use of LLINs. In this context, to determine the community’s knowledge and practices about malaria and LLINs, a study was conducted in Rudan County, one of the important malaria endemic areas in southeast of Iran.MethodsIn this cross-sectional study, 400 households in four villages were selected by cluster randomly sampling method. Community knowledge and practices about malaria and LLINs including symptoms and transmission of malaria and washing, drying and using of bed nets were investigated using pre-tested structured questionnaires. The data were analysed using SPSS.16 software.ResultsIn this study nearly 89% of the respondents knew at least one symptom of malaria and 86.8% considered malaria as an important disease. The majority of respondents (77.8%) believed that malaria transmits through mosquito bite and 72.5% mentioned stagnated water as a potential mosquito breeding place. About 46% of respondents mentioned the community health worker as the main source of their information about malaria. Approximately 44.8% of studied population washed the LLINs once in six months and 92% of them mentioned that they dry the bed nets in direct sunlight. While 94% of households reported they received one or more LLINs by government and 60.8% of respondents mentioned that LLINs were the main protective measure against malaria, only 18.5% of households slept under bed nets the night before the survey, this use rate is lower than the targeted coverage (80%) which is recommended by World Health Organization.ConclusionAlthough, majority of studied population were aware of the symptoms and cause of malaria, a majority had misconceptions about LLINs. Therefore, appropriate educational intervention by trained health workers should be developed for a behaviour change and motivating people to use LLINs which would improve malaria elimination programme.Electronic supplementary materialThe online version of this article (doi:10.1186/1475-2875-13-511) contains supplementary material, which is available to authorized users.

Central Sulawesi is one of the malaria-endemic areas in Indonesia. Anopheles nigerrimus, Anopheles barbirostris, Anopheles subpictus, Anopheles parangensis, Anopheles flavirostris and Anopheles minimus were confirmed as malaria vectors. Researchers believed that there might have a distinctly different distribution and diversity of the vectors in different ecosystems. The purpose of the current study was to investigate and analyze the distribution and diversity of suspected malaria vectors (Anopheles spp.) in various ecosystems. Adult mosquitoes were collected using some methods e.g. human man landing method, animal baited trap, mosquito caught around the cage, using sweep net and the light trap. The sporozoites of Plasmodium infecting the caught mosquitoes were identified and examined using PCR. In addition, a survey on potential breeding sites of the mosquitoes. Based on the survey results, the mosquitoes species caught in the non-forest ecosystems near the settlements and positively infected by Plasmodium were An. ludlowae, An. flavirostris, and An. vagus. Meanwhile, the malaria vectors caught in the non-forest ecosystems far from the settlements were An. maculatus and An. subpictus. The results also demonstrated that An. barbirostris was detected as a malaria vector in the coastal area near the settlement. The ponds, rivers and fish farms were potential breeding sites for the mosquitoes. The suspected malaria vectors (Anopheles spp) spread throughout ecosystems e.g. forests, non-forests and coasts. The high risk of ecosystems for malaria transmission was the non-forest ecosystems near the settlements, the non-forest far away from the settlements, and the coasts near the settlements.

“…Other industrial activities, such as construction or creation of borrow pits, can similarly produce human-made aquatic habitats that are permanent or temporary. These can become important larval habitats for some malaria vector species (Conde et al, 2015;Soleimani-Ahmadi et al, 2013;Mereta et al, 2013). Freshly excavated pits, in particular, have been found to contain abundant immature An.…”

The impact of industrial activities on vector-borne disease transmission

Industrial activities have produced profound changes in the natural environment, including the mass removal of trees, fragmentation of habitats, and creation of larval mosquito breeding sites, that have allowed the vectors of disease pathogens to thrive. We conducted a review of the literature to assess the impact of industrial activities on vector-borne disease transmission. Our study shows that industrial activities may be coupled with significant changes to human demographics that can potentially increase contact between pathogens, vectors and hosts, and produce a shift of parasites and susceptible populations between low and high disease endemic areas. Indeed, where vector-borne diseases and industrial activities intersect, large numbers of potentially immunologically naïve people may be exposed to infection and lack the knowledge and means to protect themselves from infection. Such areas are typically associated with inadequate access to quality health care, thus allowing industrial development and production sites to become important foci of transmission. The altered local vector ecologies, and the changes in disease dynamics that changes affect, create challenges for under-resourced health care and vector-control systems.

Environmental characteristics of anopheline mosquito larval habitats in a malaria endemic area in Iran

Abstract: The results of this study showed a correlation between certain environmental parameters and mosquito larvae abundance, and these parameters should be considered in planning and implementing larval control programs.
