Analysis of Dengue Patients in Dhaka Unveils Concentrated Hotspots for Hospitalization


Dengue fever is a mosquito-borne viral infection that has become a major public health concern in many tropical and subtropical regions around the world. One such region is Dhaka, the capital city of Bangladesh, which has been grappling with the burden of dengue cases for several years. Understanding the geographical distribution of dengue cases can help health authorities identify hotspots and allocate resources more effectively. This article aims to analyze the concentration of dengue patients in Dhaka and unveil the areas that require focused attention for hospitalization and preventive measures.

The Data and Methodology

To conduct the analysis, data on dengue patients in Dhaka was collected from various hospitals and healthcare facilities in the city. This data included information on the patients’ residential addresses, as well as clinical parameters such as age and severity of the disease. Geographical information systems (GIS) were used to map the locations of dengue patients and identify potential hotspots based on the density of cases. Statistical techniques were also employed to analyze the relationships between various factors and the likelihood of hospitalization.

Analyzing the Hotspots

The analysis revealed several concentrated hotspots within Dhaka where a significant number of dengue patients were being hospitalized. These hotspots were primarily located in densely populated areas with poor sanitation and inadequate vector control measures. Areas such as Mirpur, Mohammadpur, Uttara, and Gulshan were identified as the most severely affected regions. The majority of the patients in these hotspots were young adults and children, suggesting that certain demographic groups may be more susceptible to the disease.

The Impact of Environmental Factors

One key finding of the analysis was the impact of environmental factors on the concentration of dengue cases. The presence of stagnant water, which serves as breeding grounds for mosquito vectors, was identified as a significant contributor to the outbreak. Areas with a high number of construction sites and improper waste disposal practices were particularly vulnerable to dengue transmission. Additionally, the lack of green spaces and trees in urban areas may further exacerbate the problem by reducing natural mosquito control.

Socioeconomic Factors and Hospitalization Rates

Another important aspect examined in the analysis was the relationship between socioeconomic factors and the likelihood of hospitalization. It was observed that individuals from lower-income communities were more likely to be hospitalized due to dengue. Limited access to healthcare facilities, delayed diagnosis, and inadequate knowledge about preventive measures were identified as key factors contributing to this disparity. Addressing these socioeconomic barriers and improving healthcare infrastructure in vulnerable areas can help reduce the burden of hospitalizations.

Implications for Public Health

By identifying the concentrated hotspots of dengue hospitalizations in Dhaka, this analysis provides crucial information for policymakers and public health authorities. Targeted interventions and preventive measures can be implemented in these hotspots to control the spread of dengue and reduce the burden on healthcare facilities. This may include improved vector control measures, awareness campaigns, community engagement, and strategic deployment of resources. Furthermore, the analysis highlights the need for long-term planning to address the underlying environmental and socioeconomic factors contributing to the outbreak.


Analyzing the concentration of dengue patients in Dhaka revealed several hotspots that require focused attention for hospitalization and preventive measures. The study highlighted the impact of environmental factors, such as stagnant water and inadequate waste management, as well as socioeconomic factors, such as limited access to healthcare and knowledge gaps. By targeting these hotspots and addressing the underlying causes, public health authorities can effectively manage the dengue outbreak in Dhaka and improve the overall health of the population.

FAQs (Frequently Asked Questions)

1. Is dengue fever a life-threatening disease?

Dengue fever can range from mild to severe, with severe cases sometimes leading to dengue hemorrhagic fever or dengue shock syndrome, which can be life-threatening. It is important to seek medical attention if you experience symptoms such as high fever, severe headache, joint and muscle pain, and rash.

2. What preventive measures can individuals take to protect themselves from dengue?

Some preventive measures individuals can take to protect themselves from dengue include using mosquito repellents, wearing long sleeves and pants, and eliminating potential breeding sites for mosquitoes by emptying stagnant water containers.

3. How can the government address the socioeconomic barriers to healthcare access?

The government can address socioeconomic barriers to healthcare access by improving the availability and affordability of healthcare services in vulnerable areas, implementing health education programs to increase awareness, and providing financial support for those who cannot afford medical care.[3]
