 
Dengue is one of the major health risks in most tropical and subtropical regions. The mosquito-borne viral infection can cause serious health conditions. Understanding dengue’s symptoms, transmission, and prevention methods would help individuals protect themselves effectively.
What is Dengue?
This acts as the initiation of infection; the following symptoms will eventually develop.
Interestingly, the majority of infected individuals only experience mild symptoms or even no symptoms at all. In other cases, the disease can become dangerous, highly hazardous to health, known as severe dengue. The knowledge of two stages of dengue requires one to know when dengue becomes a minor disease and when it becomes a deadly disease.
Symptoms of Dengue
This infection has to be diagnosed on time to have proper treatment. Common symptoms appear in the form of high-grade fever that is very high, pain behind the eyes, tenderness of the muscles or joints, and rashes. Patient may experience mild oozing of blood and severe weakness as well.
Symptoms arise after three to fourteen days of mosquito bite. Symptoms would take a week’s time to develop in the majority of patients who acquire the disease. However, it may also be extreme; thus, complications could arise early.

What Is Severe Dengue?
Life-threatening, Severe dengue is the old term called dengue hemorrhagic fever. The condition generally occurs due to excessive response of the body’s immune system to the virus. The severe conditions of the patients lead to bleeding inside the body, organs’ failure, and strain in the respiratory system.
It is also a routine practice of severe dengue to hospitalize the patients who are in serious conditions. The doctor ensures that the vital signs of the patient are taken care of, along with supportive treatment. Therefore, it can be said that quick treatment will provide much better recovery and reduce the death rate.
Mode of transmission and Risk Factors
The primary mode of transmission of dengue virus is through mosquito bites. Aedes aegypti breeds in stagnant water, making the urban areas more susceptible. Poor sanitation, climate, and urbanization are factors that contribute to dengue outbreaks.
Other risk factors include people who live in or travel to places with high dengue prevalence. The regions include Southeast Asia, the Caribbean, and parts of Africa, where the cases of dengue are reported in large numbers. Knowing these risks helps travelers take precautions.
Prevention Strategies
Prevention of dengue occurs through minimizing the exposure and breeding of mosquitoes. Effective prevention strategies include the following:
- Clear Standing Water: Regularly drain and clean containers holding standing water. This will reduce mosquito breeding.
- Use Repellents: Apply insect repellent containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin.
- Wear Protective Garments: Wear long-sleeved shirts and long pants to reduce skin exposure.
- Installation of window and door screens to keep out the mosquitoes in houses.
- Community Actions: Organize clean-up operations at the community level, for all these could harbor breeding grounds for the mosquito.
Reduces the chances of a person getting infected very highly.
Contribution of Immunization
It forms an essential role in the prevention of dengue. The Dengvaxia vaccine protects against dengue for people between the ages of 9 to 45 years. This vaccine is only available to those who have been infected with the virus.
Presently, scientists are researching to come up with new vaccines. These vaccines will help in boosting protection to persons staying in endemic regions. Vulnerable populations must stay updated on the new vaccines.
International Response to Dengue
Global health agencies, such as the WHO, are working to reduce dengue. Their efforts are through research, surveillance, and public health campaigns. This is done to increase the level of awareness and enhance prevention methods in the global arena.
The affected countries usually have vector control programs. Vector control programs usually target mosquitoes through the use of insecticides and public education. Such practices have been successful in controlling the spread of dengue.
Conclusion
In summary, dengue fever is an important public health concern. Its symptoms, methods of transmission, and ways to prevent the disease are all knowledge that a person and community can acquire for their own well-being and safety. Proactivity will reduce the incidence of this disease in people.
To conclude, global cooperation as well as continuous research has been, and continues to be, the best course of action in combating this disease. With further cooperation and study, we might eventually create a future with no danger of dengue upon public health. Click here for the source
