Typhoid fever is a febrile illness that commonly occurs in urban areas with poor sanitation. It is usually caused by the consumption of untreated water and contaminated food. Because the S. typhi bacterium can survive in water for days, contamination of surface water—such as wastewater, freshwater, and groundwater—serves as the primary cause of typhoid fever. The patient presented to the Emergency Department of Cut Meutia General Hospital with complaints of high fever for approximately 4 days prior to admission, which had worsened over the past 2 days. The fever fluctuated and was accompanied by chills. It worsened at night and was not influenced by weather or temperature. These symptoms were accompanied by vomiting every time the patient tried to eat, nausea, abdominal pain, headache, and weakness. The patient reported vomiting the contents of their meal every time they ate, leading to a loss of appetite. These symptoms began when the patient first developed a fever. The patient also experienced abdominal pain. Spontaneous bleeding was denied. On physical examination, the patient appeared weak but was alert and oriented. On neck examination, palpable enlargement of the thyroid glands was found on the right and left sides of the neck, measuring 2x2 cm, mobile, and soft. On abdominal examination, increased bowel sounds were noted. Vital signs were normal except for the patient’s febrile temperature. Laboratory tests revealed a Tubex blood test result of scale 4 and a positive dengue IgG serology result.

Introduction: Dengue fever is a viral infection transmitted through the bite of infected female Aedes aegypti mosquito, caused by four dengue virus serotypes (DEN-1 to DEN-4), with clinical manifestations ranging from asymptomatic to severe disease and may be accompanied by warning sign. Concurrent infections, such as acute diarrhea, may worsen outcomes, particularly in children. Case Report: A nine-month-old female presented with a five-day history of intermittent fever and watery diarrhea. Additional symptoms included vomiting, lethargy, and decreased appetite. Physical examination showed a moderately ill appearance and sunken eyes. Laboratory findings revealed positive dengue IgM, negative dengue IgG, thrombocytopenia (22,000/µL), and hematocrit of 37%. The patient was diagnosed with dengue fever with warning sign and acute diarrhea. Management included intravenous crystalloid fluids, antipyretics, antibiotics, H2 receptor antagonists, and zinc supplementation. Conclusion: Dengue with warning sign and concurrent acute diarrhea in children increases the risk of morbidity and mortality. Early and appropriate management is essential to prevent disease progression and improve clinical outcomes.

Dengue fever is a disease commonly found in tropical and subtropical regions. This disease can cause severe symptoms, such as very high fever, accompanied by nausea, vomiting, headache, abdominal pain, and leukopenia (decrease in white blood cells). This infectious disease, known as dengue hemorrhagic fever (DHF), is a viral infection transmitted by the Aedes Aegyppti mosquito. This study aims to classify dengue-prone areas using the K-Means Algorithm, and to classify the factors that cause dengue in Purwodadi District, Grobogan Regency. The clustering results using the K-Means algorithm with Rapidminer tool from 266 data produced 3 clusters: cluster 0 (blue) with 138 patients dominated by Kuripan, Purwodadi, Ngambak villages, cluster 1 (green) with 31 patients in Ngraji, Nambuhan, Cingkrong villages, and cluster 2 (orange) with 97 patients in Danyang, Kalongan, Pulorejo villages. This study is expected to provide additional information for stakeholders in controlling dengue cases and increase awareness of the importance of environmental cleanliness as a preventive measure.

The high cost of colloid fluids and the large number of patients are concerns in determining which treatment standard should be chosen from several treatment alternative, where the total cost for 43 cases with a combination of crystalloid colloid fluids is IDR 209.370.993 while the total cost for 45 cases of crystalloid fluids is only UDR 146.492.268 which causes hospital losses. This study aims to determine the difference in the cost-effectiveness between crystalloid fluids and crystalloid-colloid combinations in hospitalized dengue fever patients without shock at Tangerang City Hospital. The research design used was cross-sectional with a comparative quantitative analysis method, where cost effectiveness was analyzed using the Average Cost Effectiveness Ratios (ACER) method. There were two groups of study samples: the first group, 25 patients who received crystalloid fluids, and the second group, 23 patients who received crystalloid-colloid combination fluids. This study showed a difference in the average hospitalization costs for dengue patients between crystalloid fluid therapy and crystalloid-colloid combination therapy. Hospitalization costs for dengue patients were lower in the crystalloid fluid group, with a significant difference (p=0.000). It was also found that crystalloid fluids were more cost-effective than the crystalloid-colloid combination. The implications of the study results consist of theoretical implications and practical implications. Based on the results of the analysis carried out, the crystalloid solutions are more cost-effective than crystalloid-colloid combinations. This finding can be used as a consideration in making decisions and policies that are in accordance with quality control and cost control for patients covered by the National Health Insurance (BPJS Health insurance).

Introduction: Dengue Hemorrhagic Fever (DHF) is a serious disease transmitted by the aedes aegypti mosquito. Dengue Hemorrhagic Fever (DHF) is an infectious disease transmitted through the bite of the Aedes aegypti mosquito and is still a public health problem. The high incidence of dengue fever is often caused by a lack of knowledge, attitudes, and actions of the community in carrying out appropriate prevention efforts. The goal is to identify the picture of community behavior in dengue prevention, including aspects of knowledge, attitudes, and actions. Method: was a quantitative descriptive with 100 respondents selected by random sampling in East Sidomulyo Village, Marpoyan Damai. Data were collected through questionnaires and analyzed univariately. Results: The variables of community behavior were obtained in the knowledge of most of the people who were low as many as 52 respondents (52%), most of the people's attitudes were obtained negative attitudes as many as 77 respondents (77%), the actions of the community mostly had less actions with the number of 59 respondents (59%), and the behavior of the community was relatively low. Conclusions and Suggestions: This study shows that the majority of the people of East Sidomulyo Village have lacking knowledge, attitudes, and actions in the prevention of dengue. Low preventive behavior is caused by a lack of knowledge and concern. Intensive, community based education is needed to raise awareness and preventive measures in an ongoing manner.

The low level of understanding among elementary school students regarding common diseases and their prevention can increase the risk of both communicable and non-communicable diseases from an early age. Therefore, effective health education efforts are essential to instill healthy habits in children. This community service activity aimed to improve the knowledge of elementary school students in the working area of Labuhan Sumbawa Public Health Center about common diseases and preventive measures through an interactive educational approach. The methods used included health counseling with visual media, engaging educational games, and small group discussions to encourage active participation. The activity was conducted in June 2025, involving 30 students from two elementary schools selected purposively. The educational content focused on dengue fever, diarrhea, influenza, helminthiasis, and acute respiratory infections (ARI), along with prevention strategies such as maintaining personal hygiene, consuming nutritious food, and the importance of immunization. Evaluation was carried out through pre-test and post-test assessments to measure the improvement in students’ understanding. The results showed a significant increase in students’ knowledge of the delivered material. Additionally, students demonstrated high enthusiasm and active involvement during the sessions, particularly in the educational games. These findings indicate that an interactive educational approach is effective in enhancing students’ understanding of disease prevention. This program is expected to serve as a model for sustainable health education in other elementary schools to prevent diseases from an early age and support the implementation of clean and healthy living behaviors within the school environment

In early 2024, deaths from Dengue Hemorrhagic Fever (DHF) increased again in Indonesia, with the number of cases higher than the previous year. This condition raises concerns because DHF remains a serious public health problem. The World Health Organization (WHO) emphasized that the key to reducing mortality lies not only in early detection but also in public access to fast, effective, and equitable health services. This statement aligns with the second point in the document "National Dengue Control Strategy 2021–2025" issued by the Ministry of Health, in which the government is committed to strengthening health security. In efforts to ensure this strengthening, public participation plays a crucial role, particularly through the public oversight function channeled through the media. The media acts as a bridge of information and a tool of social control over government performance, including in monitoring the provision of health services by BPJS Kesehatan. This study aims to analyze how news about health security reaches the public, using Brand24 media monitoring as an analytical tool. The research method used was descriptive qualitative, focusing on mapping issues, sentiments, and narratives developing in the digital space. The analysis showed that news containing the keyword "BPJS Kesehatan" was dominated by positive news, with several minor topics discussing aspects of public service. This finding indicates a media tendency to project a positive image of the institution, although further study is needed regarding media bias in the context of health security reporting in Indonesia. Future research is expected to explore the relationship between media framing, public interest, and the effectiveness of national health programs.  

Dengue Fever (DF) continues to be a major public health threat in Indonesia, especially in urban areas with high population density, such as Purwokerto City. This study aims to develop a predictive model to identify high-risk areas for DF outbreaks by integrating Machine Learning (ML) algorithms and Geographic Information Systems (GIS). The research utilizes historical dengue case data, meteorological parameters (rainfall, temperature, humidity), and population density as predictive variables. Three ML classification algorithms—Naïve Bayes, Logistic Regression, and Support Vector Machine (SVM)—were implemented to develop risk prediction models. Extensive data preprocessing, feature selection, and spatial integration were applied to ensure model robustness. The results show that the SVM model outperformed other methods, achieving the highest accuracy, precision, recall, and F1-score in classifying dengue risk zones. Risk maps generated through GIS visualization successfully identify priority areas for targeted interventions. The novelty of this research lies in the combination of local epidemiological data, multi-algorithm comparison, and geospatial mapping to improve early warning systems for DF in Purwokerto. This integrated approach is expected to support more effective prevention strategies and enhance public health preparedness.

The implementation of dengue fever control in Tanjungpinang City through the 1 House 1 Jumantik Movement program has not been optimal until now. The problem in controlling dengue fever through this program is that the community is inactive and does not know about the implementation of this program. The purpose of the researcher was to determine the implementation of dengue fever control through the 1 House 1 Jumantik Movement program in Tanjungpinang City. Qualitative Method and Policy Implementation theory by Marilee S Grindle. The results of the study showed (1) Content of policy, the researcher found from the indicators of the resources used, namely financial resources, the wages given were only enough for transportation costs. Insufficient resources also limited the number of jumantik cadres working, plus there was a change in funding sources to BOK which caused several health centers to experience a budget reduction in Jumantik honorariums (2) Context of Implementation found that the authority of each actor was not in accordance with the implementation manual for the 1 House 1 Jumantik Movement by the Ministry of Health. In addition, the government also did not provide guidance to the community so that many people did not know about this program.

Dengue Hemorrhagic Fever (DHF) remains a major public health concern in Pidie Regency, Indonesia. Although digital surveillance systems such as SKDR have been introduced, the effectiveness of dengue control still largely depends on the role and capacity of surveillance officers. This study aimed to explore the experiences of dengue surveillance personnel in Pidie Regency, focusing on their knowledge, reporting mechanisms, encountered challenges, and expectations regarding the surveillance system. A qualitative method with a phenomenological design was employed, involving 11 purposively selected informants. Data were gathered through in-depth interviews and analyzed using the Miles and Huberman framework, encompassing data reduction, data display, and conclusion drawing. The analysis revealed six main themes: officers' knowledge and understanding of dengue, sources of data and case collection methods, the use of digital applications for reporting and analysis, implementation challenges in the field, cross-sectoral roles and support from village governments, and officers' expectations for improvement. The findings highlight that limited resources, technical issues, and insufficient intersectoral collaboration hinder effective surveillance. Strengthening the surveillance system requires responsive strategies that consider on-the-ground challenges. A deeper understanding of surveillance officers’ field experiences is crucial for developing adaptive and sustainable public health interventions for dengue control.

Dengue Fever is a viral infection that spreads from mosquitoes to humans. In Susunan Baru Health Center, the number of dengue cases increased by 55% in 2024.  Mosquito nest eradication (PSN) with 3M Plus combination, fogging, and community service can reduce the breeding of Aedes mosquitoes and reduce Dengue Fever. The purpose of this study was to determine the relationship between 3M plus behavior and Dengue Fever in Susunan Baru Health Center, Bandar Lampung City. This method is quantitative research, case control study. The sample was 128 samples, 64 case respondents and 64 control respondents (1:1). Case samples were taken with total sampling technique, control samples were taken with purposive sampling technique. Data analysis was conducted with chi-square test (α)=0.05. Conclusion There is a significant relationship between closing water reservoirs (p value = 0.000), draining water reservoirs (p value = 0.003), recycling used goods (p value = 0.000), changing flower vase water (p value = 0.000) and sprinkling larvicide powder (p value = 0.036) with the incidence of Dengue Fever in the Susunan Baru Health Center Working Area, Tanjung Karang Barat Subdistrict, Bandar Lampung City. Keywords: Aedes, DBD, Dengue Fever, PSN, 3 M Plus.

Dengue Hemorrhagic Fever (DHF) is transmitted through the bites of Aedes aegypti and Aedes albopictus mosquitoes. Efforts that can be made to reduce the incidence of dengue fever are through the 3M plus movements (draining, burying and covering) and carrying out preventive activities such as sprinkling larvicide powder, using mosquito repellent, and planting mosquito repellent plants. The aim of this community service is to increase public knowledge about recognizing and preventing dengue fever as an effort to prevent and control the disease. The activities were carried out at Padukuhan Nologaten, Caturtunggal Village, Sleman Regency, Yogyakarta Province in May-June 2024. The activities carried out include situation analysis, preparation, implementation, monitoring and evaluation, and analysis and reporting. The participants of this activity numbered 37 people with the majority aged 46-65 years (48%) and college education background (48%). The average level of community knowledge about the prevention and control of dengue fever before counseling (pre-test) was good (89%) and sufficient (11%) and after counseling, the level of community knowledge increased to good (95%).

A healthy latrine is one of the essential sanitation facilities aimed at maintaining environmental health and improving public health in general. This research was conducted because the use of healthy latrines in Webetun Village remains low, where defecating in the forest has become a common practice among the community. This habit triggers the emergence of diseases such as diarrhea, malnutrition, undernutrition, dengue fever, and respiratory infections. This study aims to examine the behavior of latrine use in households in Webetun Village, Rinhat Subdistrict, Malaka Regency. This research uses a quantitative approach with a cross-sectional design. The study involved 66 housewives who owned healthy latrines, selected through simple random sampling. Data analysis was conducted using the chi-square test. The results showed that variables such as latrine ownership (p=0.000) and water availability (p=0.000) were significantly associated with latrine use, while knowledge (p=0.681), attitude (p=0.588), actions (p=0.007), community leader support (p=0.081), and health worker support (p=0.069) were not significantly associated with latrine use. The findings revealed that water availability significantly influences latrine use. The availability of water facilitates family members in utilizing latrine facilities for activities such as flushing and maintaining cleanliness. Water availability also contributes to user comfort in maintaining latrine hygiene. Conversely, water scarcity hinders optimal latrine use by family members, potentially reducing utilization levels. The study findings also identified a correlation between latrine ownership and its use. Families are considered critical factors in shaping individual health behavior. The relationship between proper latrine ownership and usage behavior can be seen through the role of education in increasing awareness levels for adopting a healthy and clean lifestyle. 

Cases of dengue fever (DBD) in Solo, including in Gajahan Village, have increased quite significantly. Until the beginning of the year, there were 1,010 cases of DBD recorded throughout Central Java, with 34 cases resulting in death. The purpose of this Community Service Priority problems in this caseconsist of two aspects, including health, law, Health problems include how the community can prevent the spread of Dengue Fever (DBD). While in terms of Law, it discusses community protection related to Aedes Biotechnology with Wolbachia in Handling Dengue Fever. The method of implementing the community service with a pre-test, then the presentation of material on "Education of Aedes Biotechnology with Wolbachia in Handling Dengue Fever: Health Law Study" is carried out offline, with lecture methods, demonstrations, and Q&A discussions. At the end of the material presentation session, a demonstration of making anti-mosquito spray products will be held and ended with a question andanswer session and post-test. The results of the Community Service show that there is a significant difference in the amount of income, the amount of pretest scores before receiving material exposure and the posttest scores after receiving the material.

Indonesia is a tropical country which of course cannot avoid the occurrence of dengue fever. engue fever is still one of the serious diseases faced in Indonesia. The results of the Ministry of Health of the Republic of Indonesia in 2022, the number of dengue cases reached 131.265. Prevention and eradication measures are more effective by eradicating mosquito larvae with PSN. PSN efforts require cooperation between the government and community participation. The role of eradicating mosquito nests must always be increased, includes draining water reservoirs, tightly closing water reservoirs, reusing used goods that can hold water and have the potential to become breeding grounds for mosquitoes that transmit dengue fever. In general, most residents use water reservoirs and there are piles of rubbish around the house and there are still puddles and water reservoirs. For this reason, there needs to be education for the community about eradicating mosquito nests, one of which is by utilizing used goods so that they do not become a place for the shelter and development of mosquito larvae that cause dengue fever. The method used in this community service is by providing education and counseling to the community regarding explanations regarding waste management, sorting, benefits and recycling of waste. The implementation of this PkM activity went well and smoothly. The community was enthusiastic in participating in this activity. There was an increase in public knowledge and understanding during the discussion session of the activity. It is hoped that the community can manage waste properly and correctly to avoid various diseases, especially Dengue Fever (DBD).

Background: Dengue fever is an endemic diseases caused by the dengue virus which is transmitted by the Aedes aegypti mosquito. Knowledge have a crucial role in preventing and controlling dengue fever. The purpose of this study is to examine the effectiveness of health education using the buzz group discussion method in increasing community understanding of dengue Methods: Quantitative research with quasi experimental design pre-test and post-test with Non-equivalent control group pretest-posttest. This study was conducted in Sidomulyo Timur with a total sample of 32 respondents chosen based on inclusion criteria using purposive sampling technique. Data analysis used is Wilcoxon test and Man-Whitney test. Results: There was an increase knowledge in the experimental group by 26.56%, with a good level of knowledge of 81.3% after being given health education by the buzz group method. Statistical tests obtained the results of the p value (0.000) < ? (0.05). Which means there is an increase in knowledge after the intervention. Conclusion: Health education using the buzz group method about dengue fever is effective in increasing community knowledge.

Sanitation is part of environmental health science which includes the methods and efforts of individuals or communities to control and manage the external environment which is dangerous to health and which can threaten human survival. Meanwhile, basic sanitation is the minimum sanitation required to provide a healthy environment that meets health requirements which focuses on monitoring various environmental factors that influence human health. Basic sanitation efforts include providing clean water, disposal of human waste (latrines), waste management (trash cans) and waste water disposal channels (SPAL). Through a preliminary survey conducted at the Sahabat Yatim Dormitory Orphanage and from interviews conducted by the community service team, it was discovered that several children at the Sahabat Yatim Dormitory orphanage had a fairly high history of dengue fever sufferers and there were still many conditions in the orphanage that did not meet health requirements. Thus, there is still the possibility of problems related to environmental sanitation and eradicating mosquito nests (PSN) at the Pekanbaru Orphanage Friends Dormitory orphanage. The aim of this activity is to increase the knowledge of children in orphanages about environmental sanitation and eradicating mosquito nests.This community service was carried out at the Sahabat Yatim Dormitory Orphanage on June 29 2022. The method used was health education through group counseling. The result of this community service is to increase the knowledge of children in foster care about environmental sanitation and making compost.

DHF (Dengue Hemorrhagic Fever) is a disease caused by the aedes virus. WHO states that 4,000 people worldwide have died from DHF, Banjar City in 2024 had 387 cases of DHF. Based on the results of community diagnosis using the ultrasound method, it has been determined that the priority health problem is DHF (Dengue Fever). Based on the results of the SWOT analysis, it was found that the determinant factor of the health problem is non-compliance with the 3M Plus PSN which includes: empty houses are not maintained with damp and dark conditions, the community does not understand and has not implemented the 3M Plus PSN at home, and the community only recognizes DHF prevention efforts limited to fogging. Therefore, we designed innovations through the LASKAR DBD program (Collaborative Strategic Steps for Dengue Fever) with the implementation of activities in the form of revitalizing the DBD center building as a place for socialization and counseling about dengue, fishization by giving guppy fish as larvae-eating fish, held a SAMBEL (Equal Learning) program, namely the installation of 3M Plus PSN stickers in each house as educational material as well as counseling activities for cadres and school children related to DHF, then held a BALADO program (Together Fighting Dengue with ovitrap) which is a modified SAMT ovitrap demonstration activity.

Indonesian people mostly tend to ignore health, especially dengue fever because the symptoms that arise are similar to common fever, this causes people with common fever symptoms to be reluctant to see a doctor. This study aims to help the public recognize the symptoms of dengue fever early by using the implementation of the fuzzy method in the dengue fever disease diagnosis system that uses specific datasets as a reference. Mamdani's fuzzy method, which is based on linguistic frameworks and fuzzy concepts, allows for the management of knowledge from experts for intuitive decision-making. The test results using the Confusion Matrix, the system showed an accuracy of 92.8%, an average precision of 90.6%, a recall of 95.8%, and an F1-Score of 92.6%, with an effectiveness value of 100%. This study proves that the system is able to provide information about dengue fever, diagnose based on symptoms, and offer solutions for its treatment.

Dengue fever, malaria, and other mosquito-borne diseases remain significant health problems and challenges in various regions, especially in rural areas. Dengue fever (DBD) is caused by the dengue virus types 1-4, which are transmitted through the bites of Aedes aegypti and Aedes albopictus mosquitoes. The majority of the residents of Karya Mukti Village work as rubber tappers. They usually start their activities early in the morning or even before dawn. However, mosquitoes are most active in the morning and late afternoon, making the local community highly vulnerable to mosquito bites. To address this issue, the people of Karya Mukti Village still widely use mosquito repellents available on the market, which contain harmful chemicals that pose risks to both health and the environment if used over the long term. Therefore, this community service initiative aims to conduct outreach and hands-on training on the use of citronella (Cymbopogon nardus) as a natural mosquito repellent alternative. This program is carried out using a socialization and product-making approach through participatory engagement, where Dasawisma (women's community groups) are encouraged to identify their needs and challenges, as well as appropriate solutions to address them. By involving Dasawisma members in the learning and production process of natural mosquito repellents, it is hoped that they will gain better knowledge and skills in making natural mosquito repellents.
