I. What is dengue fever?
Dengue fever is an acute infectious disease caused by the dengue virus. It is witnessed mainly in tropical and subtropical regions globally, especially in Southeast Asian and African countries. This disease can be fatal if not detected and treated promptly.
II. Classification of dengue fever
Dengue fever can be classified into two main types:
1. Dengue hemorrhagic fever (DXD): This is the most common type of dengue fever. Construction production is divided into four types: light production, medium production, heavy production and shock production. These types vary in severity and symptoms.
2. Strange hemorrhagic fever (DHF): This type is rare and often causes serious complications such as encephalitis or hepatitis. Dengue fever can be fatal and requires highly technical medical care.
III. Symptoms of dengue fever
Symptoms of dengue fever may include:
- Rapid increase in body temperature, often above 38 °C.
- Severe headache and eye pain.
- Bone and joint pain.
- Fatigue and loss of energy.
- Loss of appetite and skin rashes may appear.
- Bleeding gums, bleeding limbs, or bleeding from the nose or mucous membranes.
- Nausea and vomiting.
- Loss of interest in food.
- Headache after vomiting.
IV. Stages of dengue fever
Dengue fever has different stages, including:
1. Fever phase: This phase begins with fever and other non-specific symptoms.
2. Intensification phase: During this phase, bleeding symptoms and other manifestations such as skin rashes, bleeding gums or mucous membranes may appear. Patients may become tired and have decreased function.
3. Recovery phase: During this phase, symptoms gradually decrease and the patient begins to recover. However, some cases can progress to a more severe stage and cause dangerous complications.
V. Agent causing dengue fever
Dengue fever is caused by the dengue virus. This virus is transmitted from person to person by Aedes aegypti mosquitoes, Aedes albopictus mosquitoes and other mosquitoes during blood feeding. These mosquitoes usually live in freshwater environments and are active mainly at night.
In addition to the dengue virus, there are a number of other factors that may contribute to the development and spread of the disease, including:
1. Living environment: The intensification of urban areas and improper construction of regulations on environmental sanitation and waste management can create a favorable environment for dengue mosquitoes to live and reproduce. product.
2. Water quality: Dirty fresh water or stagnant water in water tanks that are not properly maintained can be a breeding ground for dengue mosquitoes.
3. Human behavior: Failure to eliminate mosquito breeding sites, failure to use effective mosquito killers, and failure to proactively protect oneself from dengue mosquitoes (such as using mosquito repellant cream, especially at night). night) can increase the risk of infection.
4. Genetic factors: Some genetic factors may make some people more susceptible to severe illness when exposed to the dengue virus.
In preventing and controlling dengue fever, the focus should be on dengue mosquito eradication and habitat management. At the same time, increasing community education on prevention measures and recognizing symptoms of the disease will help prevent the spread and reduce the death rate from dengue fever.
