Dengue Fever

Dengue Fever is a viral infection transmitted by the bite of infected Aedes mosquitoes, causing epidemics worldwide, especially in countries with hot and humid climates like Thailand.

In Thailand, dengue fever is one of the most prevalent infectious diseases, especially during the rainy season. The disease can occur in both rural and urban areas and affects all age groups, including children and adults.

Dengue fever is caused by any one of four types of dengue viruses.  Should you have had dengue fever in the past, you still can be infected again by the other virus types.  In addition, previous infection with dengue fever increases your risk of severe symptoms if you get dengue fever again.

  • History-taking related to travel history or risk factors.
  • Blood tests to detect the virus or related antibodies.


  • There is no specific drug that can directly treat dengue fever. The treatment usually focuses on symptom relief and might include administering fluids and electrolytes intravenously.
  • In severe cases, a large amount of fluids and electrolytes may be required, and additional treatments such as blood transfusion might be necessary.
Dengue fever can protect by vaccine


  • Vaccine: If you live in an area where there’s an outbreak or at risk of infection, getting vaccinated might be another preventive measure.
  • Eradicate mosquito breeding sites: Eliminate breeding grounds for mosquitoes, such as water bottles, rainwater pipes, water tanks, or use chemicals to kill mosquito larvae.
  • Prevent mosquito bites: Use mosquito repellent and wear clothing that covers the skin. Apply skin repellents or spray them on clothes. Use mosquito nets when sleeping.
  • Monitor symptoms: If initial symptoms resembling dengue fever appear, such as high fever, body aches, and headaches, you should see a doctor immediately for diagnosis and treatment.

Would it be better if we could prevent dengue fever with a vaccine?

Dengue vaccine

The dengue vaccine is one method to prevent dengue fever. The dengue vaccine helps the body’s immune system to develop immunity against the dengue virus.

Who should get the vaccine?

  • Those aged between 4 to 60 years at the time of the first vaccine dose.
  • Individuals residing in areas with dengue fever outbreaks.
  • People traveling to areas with dengue outbreaks.
  • It’s recommended for those who have been previously infected with dengue to get vaccinated to prevent more severe infections in subsequent encounters.


  • Avoid administering this vaccine to pregnant women or those breastfeeding.
  • For those who have recovered from dengue, it is recommended to wait at least 6 months before receiving the dengue vaccine. After infection, the body will have immunity against the disease, which decreases over time. Vaccination during a period of high immunity might reduce the vaccine’s efficacy.

Side effects of the dengue vaccine:

The dengue vaccine is safe. The majority of side effects from the dengue vaccine are usually mild and temporary, such as pain or swelling at the injection site, slight fever, or feeling fatigued. These symptoms typically improve within one or two days.
