In the rainy season, dengue fever outbreaks and spread very quickly in the community. If no preventive measures and timely treatment, patients can have dangerous complications.
What is dengue?
Dengue is an infection of the dengue virus by a mosquito bite. The disease usually occurs in tropical and subtropical countries.
Mild dengue fever usually causes high fever, rash, muscle and joint pain. The more serious form, also known as Dengue hemorrhagic fever, can cause serious bleeding, sudden drop in blood pressure and death.
Each year, around the world there are millions of cases of Dengue virus infection. This situation is most common in Southeast Asia, the islands of the Western Pacific, South America and the Caribbean.
Is dengue contagious?
Dengue fever is caused by a virus, so it is definitely an infectious disease. So, what is the main route of transmission? In fact, the virus is transmitted in three main ways:
Spread from mosquitoes to humans
Aedes aegypti mosquito becomes infected and bites a healthy person who will spread the Dengue virus to that person. After being infected, mosquitoes still have the ability to spread the virus to others.
Spread from person to mosquito
Mosquitoes can become infected after burning people infected with the dengue virus. These can be people who have symptoms of dengue fever, without any signs or signs of disease.
The duration of transmission of the virus to mosquitoes can take place 2 days before the patient shows signs of dengue fever and lasts up to 2 days after the fever is gone.
Spreads through blood sampling or needle jars
A healthy person can become infected with the virus if they receive blood from an infected person or share needles with them. However, this route of infection is usually less common than that of mosquitoes.
What are the symptoms of dengue?
Many people, especially children and adolescents, may not show any dengue symptoms if the disease is mild. Symptoms usually occur 4 to 7 days after a mosquito bite.
The disease usually causes high fever (39-40ºC) with the following symptoms:
- Musculoskeletal pain
- Eye sockets
- Swelling of glands
Most people will recover within a week or more. However, in some cases, the signs of illness can worsen, even life-threatening. At this point, blood vessels will be damaged and ooze. The number of cells that form blood clots in the blood (platelets) decreases. This will cause dengue, a serious condition that can be life-threatening. Symptoms of this condition include:
- Severe abdominal pain
- Persistent vomiting
- Bleeding at the gums or nose
- Blood in urine, stool or vomit
- Bleeding under the skin, may look like bruises
- Shortness of breath or rapid breathing
- Cold and moist skin
- Uneasy and sad
Get medical help right away if you have serious symptoms, such as severe abdominal pain, vomiting, difficulty breathing, bleeding gums or nose, blood in your stools or vomit.
How can dengue be diagnosed?
Diagnosis can be difficult because dengue signs and symptoms can be confused with other illnesses, such as malaria, leptospira, and typhoid.
Your doctor may ask for your medical history, recent travel history. Describe your trip in detail to help your doctor diagnose it correctly.
In addition, your doctor may order blood tests to detect Dengue virus or other similar viruses, such as Zika or chikungunya.
Effective dengue treatment
At present, there is no specific treatment for dengue. Your doctor may recommend that you drink plenty of fluids to avoid dehydration when you vomit and have a high fever.
To help relieve pain and reduce fever, you can take paracetamol. However, nonsteroidal anti-inflammatory drugs should not be used, such as aspirin, naproxen or ibuprofen, because of the risk of bleeding.
When you have serious dengue fever, you need:
- Hospitalized for treatment
- Infusion and electrolytes
- Monitor blood pressure
- Blood transfusion
During the recovery period, you should watch for signs of dehydration and see a doctor immediately if you have the following symptoms:
- Less urination
- Little or no tears
- Dry mouth or lips
- Lethargy or confusion
- Extremely cold or moist skin
Prevention and control of dengue fever
If you know you have dengue fever, avoid mosquito bites during the first week of illness. The virus can move through the blood at this time, so you can transfer the virus to the infected mosquitoes. Infected mosquitoes will continue to spread to others.
Currently, the main risk factor for a person who is easily infected with dengue is living near mosquito breeding areas. Some ways to prevent this disease include:
Prevention of mosquito reproduction
- Do not let mosquitoes lay eggs and reproduce by clearing the bush around the house, smashing jar cover jar …
- Drop fish into large water containers (tanks, wells, jars, jars …) to kill larvae, larvae
