INTRODUCTION: Dengue is a serious public health problem worldwide, with cases reported annually in tropical and subtropical regions. Aedes aegypti (Linnaeus, 1762), the main vector of dengue, is a domiciliary species with high dispersal and survival capacities and can use various artificial containers as breeding sites. We assessed potential container breeding sites of A. aegypti in the municipality of Caxias, Maranhão, Brazil. METHODS: In the initial phase, we analyzed 900 properties in 3 neighborhoods during the dry and rainy seasons (August-October 2005 and February-April 2006, respectively). During the second sampling period, September 2006-August 2007, we used 5 assessment cycles for 300 properties in a single neighborhood. RESULTS: During the dry and rainy seasons, water-storage containers comprised 55.7% (n = 1,970) and 48.5% (n = 1,836) of the total containers inspected, and showed the highest productivity of immature A. aegypti; we found 23.7 and 106.1 individuals/container, respectively, in peridomicile sites. In intradomicile sites, water-storage containers were also the most important breeding sites with 86.4% (n = 973) and 85.6% (n = 900) of all containers and a mean of 7.9 and 108.3 individuals/container in the dry and rainy seaso-October 2006 (1,342). The highest number of positives (70) was recorded in May, mostly (94%) in storage containers. CONCLUSIONS: Storage containers are the principal and most productive A. aegypti breeding sites and are a major contributing factor to the maintenance of this vector in Caxias.

<span lang="EN-US">The incidence of dengue hemorrhagic fever (DHF) is still a public health problem in Indonesia. Observations over a period of 20 to 25 years since the beginning of  the discovering of the disease, has show the increase of the diseases incidence every five years. The purpose of this study are 1) study the diversity of <em>Aedes’</em>s mosquitoes in Sukabumi City, 2) measure the <em>Aedes </em>population based on the number of eggs and ovitrap index, and 3) to know the correlation between ovitrap index and house condition. <em>Aedes</em> eggs were collected from 14 villages in Sukabumi City that has the highest incidence rate, started from May 2015 until August 2015. Collecting eggs is done by setting a trap eggs (ovitrap) as many as 230 pieces in 115 homes (indoor and outdoor). The results showed that <em>Ae. aegypti </em>were found inside houses and <em>Ae. albopictus </em>were outside houses.<em> </em>The number of eggs collected from ovitrap inside the houses were three times more than those collected from outside. Ovitrap index inside houses was 60%, or 1.6 times more than the ovitrap index outside the houses (37%) in 14 villages in Sukabumi. Houses with poor ventilation and sanitation increased the risk 3.09 times of number of ovitrap index. The results of this study could be use as basic information for the communities to improved environment hygiene through reduced mosquito breeding sites, thus degraded the incidence of dengue</span>

UNSTRUCTURED Aedes aegypti is a vector for the transmission of diseases such as dengue fever, chikungunya, Zika fever, and yellow fever. In 2016, over one million cases of these diseases were reported in Brazil — an alarming public health issue. One of the ways of controlling the disease is by inspecting and neutralizing the places where the Aedes aegypti lays its eggs through the repository of data obtained from the Ministry of Planning, Development, and Administration. In this work, we propose a multi-criteria analysis to create an index for the inspections reported through the system. We applied part of the proposed analysis to a database of inspections in government buildings to test our proposition via the generation of a heat map, which let us draw some conclusions and propose future studies.

Introduction: Cholera remains a major public health problem that causes substantial morbidity and mortality in displaced populations due to inadequate or unprotected water supplies, poor sanitation and hygiene, overcrowding, and limited resources. A cholera outbreak with 224 cases and four deaths occurred in Kakuma Refugee Camp in Kenya from September to December 2009. Methodology: We conducted a case-control study to characterize the epidemiology of the outbreak. Cases were identified by reviewing the hospital registry for patients meeting the World Health Organization (WHO) case definition for cholera. For each case a matched control was selected. A questionnaire focusing on potential risk factors was administered to cases and controls. Results: From 18 September to 15 December 2009, a total of 224 cases were identified and were hospitalised at Kakuma IRC hospital.  Three refugees and one Kenyan national died of cholera. V. cholerae O1, serotype Inaba was isolated in 44 (42%) out of 104 stool specimens collected. A total of 93 cases and 93 matched controls were enrolled in the study. In a multivariate model, washing hands with soap was protective against cholera (adjusted odds ratio [AOR] =0.25[0.09-0.71]; p < 0.01), while presence of dirty water storage containers was a risk factor (AOR=4.39[1.12-17.14]; p=0.03). Conclusion:  Provision of soap, along with education on hand hygiene and cleaning water storage containers, may be an affordable intervention to prevent cholera.

Dengue fever remains a public health problem. Environmental factors influence the mosquito Aedes aegypti’s growth, especially if there are many containers in the neighborhood. The community of Nanggungan Village have a habit of storing water in containers, therefore, they risk to become breeding sites for mosquitoes. This study aims to identify the Maya Index status of Aedes aegypti between Tegalrejo and Krajan Kidul Village. The research was observational with a cross-sectional design. Total samples were 200 homes, which 100 homes from Tegalrejo and 100 homes from Krajan Kidul Village, taken by simple random sampling. The measurement of variables employed observation sheet and analyzed in a descriptive approach. The number of containers observed in the Tegalrejo Village was 394 units, and Karajan Kidul Village was 391 units. Maya Index statuses in Tegalrejo (92%) and Krajan Kidul Village (88%) were low. Maya Index status in Krajan Kidul (13%) was higher than Tegalrejo Village (8%). House Index (HI) in the Tegalrejo (18.0%) was lower than Krajan Kidul Village (25.0%), Container Index in Tegalrejo (5.30%) was lower than in Krajan Kidul Village (8.95%), Breteau Index in Tegalrejo (21.0%) was lower than in Krajan Kidul Village (35.0%), Density Figure in Tegalrejo and Krajan Kidul Village indicated a scale of 3 and 4. Based on the MI’s status, Tegalrejo and Krajan Kidul Village were included as a low-risk category of mosquito breeding sites. Based on the density number of larvae, two villages have a moderate risk of Dengue Fever transmission. The community should implement the Mosquitoes Breeding Sites Eradication Program (PSN 3M Plus) and minimize the presence of the containers.

Dengue is caused by an RNA virus, which has 4 identified variations present in the human environment. Its main symptomatological manifestations include fever, muscle pain (myalgia), retro ocular pain, joint pain (arthralgia), headache (headache), nausea, vomiting and others, such as rash. This article aims to show the number of confirmed dengue cases in Brazil between 2008 and 2012. In Brazil, dengue is characterized as a major public health problem, being one of the diseases of an infectious nature that is very present. Some factors, such as the climate (predominantly tropical), deficient infrastructure of the urban environment, in addition to demographic expansion, which occurs in a disorderly manner, can provoke and possibly justify this national scenario. It represents a major public health problem, since the control of the disease depends on the fight against its vector, which spreads very easily in the country, due to climatic and anthropic factors. For the disease to be tackled efficiently in the country, the most effective method is to combat the vector. Garbage and materials must be efficiently separated and stored in suitable locations for further recycling, so that they do not accumulate water and become mosquito breeding sites.

Abstract Our article documents the presence of Aedes albopictus (Skuse) from urban and rural locations in the lower Himalaya Mountains, northern Pakistan. Larvae were collected from graveyards, junkyards, plant nurseries, parks, and houses. Used tires, bird drinking pots, and water storage containers were the most common containers used by this mosquito. In the absence of Aedes aegypti (L.) (Diptera: Culicidae), Ae. albopictus appears to be the primary vector of recent dengue virus outbreaks.

Development Goals

Malaria is a serious public health problem in Indonesia. This disease is one of several indicators that have been targeted by the Millennium Development Goals (MDGs) 2015 to become Sustainable Development Goals (SDGs). In malaria-endemic areas such as in Kokap, Kulon Progo, Yogyakarta, reported malaria cases declined in 2000 with no case, but increased in 2011 following by some outbreaks in 2012. Future outbreaks could be avoided when health personnel including Primary Health Care (PHC) microscopists and entomologist surveyors were equipped with adequate trainings related to malaria. This training also be used for refreshment for existing personnel to support elimination at the Kokap I, Kokap II, and several nearby PHCs. In October 2013, the Department of Parasitology, Faculty of Medicine, Public Health, and Nursing, Universitas Gadjah Mada carried out microscopic training and basic entomology related to malaria in the working area of PHC in Kokap. Training methods were giving material and direct activities in the field. The training provided basic entomology training, malaria microscopic training and malaria vector mapping using a Global Positioning System (GPS). The training facilitated PHC personnel to do correct identification of Plasmodium species, identification of old and new vector breeding sites, and found out how to map vector distribution and malaria cases in their area. The results showed that there was an increase in knowledge from PHC personnel who participated in the pre-test and post-test. From field activity, three adult mosquitoes species were found i.e. Anopheles vagus, An. annularis and An. maculatus. Nulliparous and parous mosquitoes from adult mosquito based on the examination of their tracheole skeins of ovarium were found from the collected mosquitoes although oocyst in midgut and sporozoite in salivary gland were not found during adult mosquito surgical. Similar trainings were expected to be applied in other similar areas in the future.
