Dengue is one of the most rapidly spreading mosquito-borne diseases in the world, especially in tropical countries like Bangladesh. Every year, thousands of people suffer from this illness, and many even lose their lives. Caused by the bite of the Aedes mosquito, dengue has become a major concern for public health authorities, particularly during the monsoon and post-monsoon seasons when mosquitoes breed in stagnant water. The disease spreads quickly in densely populated urban areas, often resulting in widespread outbreaks.
In Bangladesh, dengue cases increase significantly during the rainy season when water collects in containers, drains, and construction sites—creating ideal breeding grounds for mosquitoes. Schools, hospitals, and residential areas are often affected. The symptoms of dengue range from high fever and severe headache to muscle pain, skin rashes, and bleeding in severe cases. Early diagnosis and proper medical care are essential to prevent complications.
Writing a dengue paragraph helps students understand the causes, symptoms, effects, and prevention methods of this life-threatening disease. It also raises awareness about the importance of cleanliness, public hygiene, and health education in controlling mosquito-borne diseases.
Causes and Symptoms of Dengue
Dengue is caused by the dengue virus, which is transmitted to humans through the bite of infected female Aedes mosquitoes, primarily Aedes aegypti and Aedes albopictus. These mosquitoes are active during the daytime, especially in the early morning and late afternoon. Unlike other mosquito species, Aedes mosquitoes breed in clean, stagnant water found in flower pots, buckets, tires, and uncovered water tanks. Urban areas with poor drainage systems and improper waste disposal are particularly vulnerable.
Once a person is bitten by an infected mosquito, the virus enters the bloodstream and causes a variety of symptoms. The most common symptoms of dengue include high fever, severe headache, pain behind the eyes, joint and muscle pain, and skin rashes. Some people may also experience nausea, vomiting, and fatigue. These symptoms usually appear 4–10 days after the mosquito bite and can last for up to a week.
In more severe cases, dengue can lead to Dengue Hemorrhagic Fever (DHF) or Dengue Shock Syndrome (DSS), which are life-threatening. These conditions involve internal bleeding, low blood pressure, organ failure, and in some cases, death. Children, the elderly, and those with weak immune systems are at higher risk of developing severe symptoms.
Understanding the symptoms and causes of dengue is crucial for early diagnosis and treatment. When writing a dengue paragraph, students should highlight these health risks to promote awareness and prevention in their communities.
Prevention and Control Measures
Since there is no specific medicine or vaccine for dengue in most countries, prevention is the best cure. The first step in preventing dengue is controlling the population of Aedes mosquitoes. This can be done by removing stagnant water from containers, flower pots, buckets, and unused tires. Water tanks and barrels should be tightly covered, and mosquito repellents should be used, especially during the day when Aedes mosquitoes are most active.
Wearing full-sleeved clothing, using mosquito nets, and keeping windows and doors closed with screens can also reduce the chances of mosquito bites. Using mosquito coils, electric repellents, or aerosol sprays during peak mosquito hours is also effective.
Community involvement plays a crucial role in dengue prevention. Schools and local organizations should run cleanliness drives and awareness programs. People must be educated on the dangers of mosquito breeding and the importance of reporting symptoms early.
Local governments and city corporations need to take responsibility by cleaning drains, clearing garbage, and regularly spraying insecticides in high-risk areas. Media outlets, especially television and social media, can also play an important role in spreading awareness.
When students write dengue paragraph, including these prevention tips shows their understanding of the practical steps individuals and communities can take to protect themselves.
