Dengue fever is an acute infectious disease caused by the dengue virus and transmitted primarily by the Aedes aegypti mosquito in urban environments and Aedes albopictus in rural settings. This disease is endemic in many tropical and subtropical regions and is a significant public health concern due to its potentially severe clinical manifestations. This case study presents an 8-year-old boy who was admitted to the hospital with complaints of a high-grade fever lasting for approximately three days. The fever was intermittent and accompanied by chills, which raised suspicions of a viral infection. In addition to fever, the patient also experienced dizziness with a spinning sensation, occasional cough, and flatulence. A thorough clinical evaluation was conducted, including history taking, physical examination, and supporting laboratory tests. Based on the clinical findings and laboratory results, the patient was diagnosed with dengue hemorrhagic fever (DHF) grade I. DHF grade I is characterized by fever, positive tourniquet test, and evidence of plasma leakage without spontaneous bleeding. The patient was managed with supportive therapy, including fluid replacement and close monitoring of vital signs and hematocrit levels to prevent the progression to more severe stages of dengue. No significant complications occurred during the hospital stay. After a period of observation and clinical improvement, the patient was discharged in good condition. This case highlights the importance of early recognition and accurate diagnosis of DHF in pediatric patients, especially in endemic areas. Prompt and appropriate management is essential to prevent complications and ensure recovery. Continuous public health education and vector control remain key strategies in reducing dengue incidence and severity.

Dengue hemorrhagic fever (DHF) is an infectious disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito, and it is often found in children aged 2-10 years. One of the factors causing Dengue Hemorrhagic Fever is a decrease in platelet values. This study aims to analyze the correlation between platelet values ​​and severity based on clinical manifestations of Dengue Hemorrhagic Fever at the Gending Health Center. The type of research was correlational analytic with Cross Sectional Design. The population was 44 respondents. The sample used Dengue Hemorrhagic Fever patients by Accidental Sampling. The instrument used is an observation sheet to measure platelet values ​​with the severity of Dengue Hemorrhagic Fever. Data was analysed  with One Way Anova Test. The results of the study obtained platelet values, namely the mean value of 150,454.60, the median value of 151,999.60, the mode value of 152,000, the minimum value of 60,000, the maximum value of 182,000. The degree of severity based on the clinical manifestations of Dengue Fever, the majority of patients were grade 2, namely 26 patients (59.1%). Analysis test using one way anova test obtained p value = 0.000 with a significant value of p value <α = 0.005 which means there is a correlation between Platelet Values ​​and the Degree of Severity Based on Clinical Manifestations of Dengue Fever at the Gending Health Center. Normal platelet values ​​can also be high and low platelet values ​​can also be low due to other factors, namely age, gender, weight and immune factors.

Dengue Hemorrhagic Fever (DHF) remains a major public health issue in Indonesia, particularly in endemic areas like Simpang III Sipin Village. This disease is transmitted by Aedes sp mosquitoes, and the presence of their larvae is a key indicator of the potential spread of DHF. Environmental conditions, such as water reservoirs and humidity, alongside community behaviors, play significant roles in supporting the growth of these mosquito larvae. Therefore, research is needed to identify the factors influencing the presence of Aedes sp larvae. Methods: This study utilized a cross-sectional design with a quantitative approach. The sample consisted of 143 households, selected using purposive sampling techniques. Data were collected via questionnaires and direct observations. Additionally, measurements of environmental conditions such as air humidity and temperature were taken using a hygrothermometer. The variables under study included knowledge, attitudes, behavior regarding water reservoir drainage (TPA), number of TPAs, air humidity, and air temperature. Results: Data analysis was conducted using the Chi-Square statistical test to determine the relationships between the variables. The results indicated that factors like knowledge level (p = 0.008), attitude (p = 0.008), behavior related to draining water reservoirs (p = 0.001), number of water reservoirs (p = 0.013), and air humidity (p = 0.004) were significantly related to the presence of Aedes sp larvae. However, air temperature did not show a significant relationship (p = 0.675). Conclusion: High humidity environments encourage the growth of mosquito larvae, and insufficient knowledge and inadequate preventive behaviors contribute to increased mosquito populations, exacerbating the risk of DHF transmission.

Background: Dengue Hemorrhagic Fever is a health problem that is very rapidly transmitted, especially in endemic areas in Indonesia, one of which is in Jambi City. Indicators of DHF control activities are measured by the incidence rate per 100,000 population (IR) and the mortality rate (CFR). IR in 2018 was 23.28 per 100,000 population and CFR in 2018 was 0.36%. Although there has been a decrease in CFR every year, the incidence of DHF cases and deaths due to DHF still occur every year in 11 districts/cities in Jambi Province. Method: This study aims to analyze the determinants of the incidence of Dengue Hemorrhagic Fever (DHF) in the Aur Duri Health Center Working Area in 2024. The case control study design, the study was conducted from February to September 2024. This study used primary data from 2024 with a sample of 68 respondents. The variables used are Gender, Residential Density, House Condition, Hanging Clothes Habits, 3M Plus Behavior and Cleaning Water Reservoirs. Conclusion: This study found that the variables related to the incidence of DHF in the Aur Duri Health Center work area in 2024 were the variable of hanging clothes ( p-value = 0.012); 3M Plus Behavior ( p-value = 0.001); and the habit of cleaning water reservoirs ( p-value = 0.007). For the community, it is necessary to always increase self-protection efforts and for the Aur Duri Health Center, it can provide training or movements to eradicate or stop the transmission of DHF.

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus which is transmitted through the bite of Aedes aegypti or Aedes albopictus. This mosquito is a fast-growing mosquito and causes nearly 390 million people to be infected every year. The symptoms of Dengue Hemorrhagic Fever are similar to dengue fever. Dengue Hemorrhagic Fever has several other symptoms such as continuous heartburn, bleeding in the nose, mouth, gums, and bruising on the vector's skin. Dengue Hemorrhagic Fever (DHF) is an infectious disease that often causes outbreaks and causes death, especially in children. The One House One Jumantik Movement (G1R1J) is community participation and empowerment by involving every family in examining, monitoring and eradicating mosquito larvae to control vector-borne diseases, especially dengue fever, through the cultivation of 3M PLUS Mosquito Nest Eradication. 

Typhoid fever is one of the main causes of death and morbidity in densely populated areas and unhygienic environments. The most common causative agent of typhoid fever in children is Salmonella typhii. Typhoid fever is enteric fever with main clinical symptoms such as abdominal pain and fever. Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by dengue viruses types I-IV with clinical manifestations of fever lasting 2-7 days accompanied by bleeding symptoms and if a shock occurs, the death rate is quite high. This case report is an 8 years old girl with complaints of fever accompanied by abdominal pain, nausea and vomiting and headache. On physical examination, it was found that the patient's general condition appeared to be moderately ill, composmentis consciousness, pulse 86 times/minute, respiratory rate 22 times/minute, temperature 36.5 °c, and the patient's SpO2 was found to be 98%. From the supporting examination, it was found that the tubex value increased by +4. The Dengue results showed Dengue IgG (+) and IgM (-).

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.

Efforts to control Dengue Hemorrhagic Fever (DHF) through breaking the chain of DHF transmission, namely preventing Aedes aegypti mosquito bites. This community activity aims to control and prevent DHF through Mosquito Nest Eradication (PSN) 3M Plus. DHF is still increasing and is a health dilemma. Lack of public enlightenment on preventing DHF through PSN 3M Plus activities is the cause of DHF continuing to increase every year. This Community Service activity was carried out using the Rapid Action method which was followed by the Community and the Family Empowerment and Welfare Group (TIM PKK) of Labuhan Sumbawa Village, Labuhan Badas District along with students of the Public Health Undergraduate Study Program in accelerating the optimization of the implementation of PSN 3M Plus which was carried out on Friday, January 10, 2025. It is hoped that there will be ongoing intervention related to the implementation of PSN 3M Plus in order to continuously strive for the active participation of the community and (TIM PKK) of Labuhan Sumbawa Village, Labuhan Badas District in carrying out PSN 3M Plus independently, especially in the 1 house 1 mosquito larvae movement. The community needs to be reminded of the importance of PSN 3M Plus which is easy, cheap, safe, and effective

Dengue fever (DHF) is an infectious disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito. This disease is a major health problem in many tropical countries, including Indonesia. Identification and classification of DHF patients is very important to prevent further spread and to provide appropriate medical treatment. In this study, the classification of DHF disease is carried out using the K-Means algorithm, which is one of the methods in machine learning used to classify data based on similarity of features. This study aims to apply the K-Means algorithm in classifying DHF cases based on data on symptoms that appear in patients, such as high fever, joint pain, skin rashes, and others. The data used includes patient medical records that record various clinical and demographic parameters. The K-Means algorithm is used to group the data into clusters that describe the severity category or potential risk of dengue disease. The results showed that the K-Means algorithm can be used to cluster DHF patients well, with the division of groups that can describe the severity of the disease. Evaluation was conducted using metrics such as silhouette and cluster validity to assess the effectiveness of the algorithm in performing classification. This model is expected to help medical personnel in decision-making, provide early warning, and improve rapid response to dengue cases.

Dengue Hemorrhagic Fever (DHF) is a disease caused by the Dengue virus and has a significant impact on public health, especially in tropical areas. Early diagnosis and prediction of DHF risk are essential to prevent complications and improve medical care. This study aims to develop a DHF risk prediction model using the Decision Tree method based on clinical symptoms and laboratory data. The data used include symptoms such as fever, joint pain, rash, and laboratory results such as platelet count and hematocrit. The Decision Tree model was chosen because of its ability to handle data with various variables and provide easy-to-understand interpretations. The research data were taken from patients diagnosed with DHF in several hospitals during a certain period. The dataset was then analyzed to find relevant patterns that could predict a high risk of DHF. The model training and testing process was carried out using cross-validation techniques to ensure prediction accuracy. The results showed that the Decision Tree model had an accuracy rate of 96.95% and consistent results from cross-validation which produced an average accuracy of 92.8%,, with good sensitivity and specificity in predicting DHF risk based on a combination of clinical symptoms and laboratory data. Factors such as low platelet count and fever symptoms lasting more than three days were found to be significant predictive variables. In conclusion, this Decision Tree model has the potential to be used as a tool in early prediction of DHF risk, which can help medical personnel in clinical decision making and patient management. Further development can be done by adding other variables such as epidemiological data to improve model performance.

The methods used involved socialization, spray-making demonstrations, and testing its effectiveness against Aedes aegypti mosquitoes. The results showed that the spray produced was able to repel up to 90% of mosquitoes at the highest concentration (10%). This program not only increased public awareness of DHF prevention but also empowered them to create products beneficial for health and the environment.

Abstract. Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito. This disease continues to be a serious health problem in Indonesia, with high incidence rates in various regions, including rural areas. Efforts to prevent DHF are often focused on controlling mosquito vectors through various methods, one of which is the use of insecticides. However, the use of chemical insecticides can have negative impacts on human health and the environment. Therefore, this research develops a natural alternative in the form of Anti Mosquito Spray and Hand Sanitizer made from lemongrass (Cymbopogon citratus). Lemongrass was chosen because it contains citronella, a compound proven to have activity as a repellent or mosquito deterrent. This study aims to evaluate the effectiveness of lemongrass-based mosquito repellent spray as well as its capability as a hand sanitizer. The results show that this product is not only effective in preventing mosquito bites but also safe to use as a hand sanitizer, making it a practical and environmentally friendly solution in the prevention of DHF.
