Dengue Fever in Children: Protecting Your Child with a Vaccination


Dengue fever, a mosquito-borne illness caused by the dengue virus, is a major public health concern in tropical and subtropical regions like Bangkok. While symptoms in children can range from mild to severe, the potential for serious complications like dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) makes prevention crucial. Although only a small percentage (around 10%) of those with severe symptoms have DHF or DSS, the risk of death becomes significant if these complications are not promptly addressed. Fortunately, there was a very low mortality rate for dengue fever, with less than 1% of cases proving fatal. Early diagnosis and treatment are critical to maintaining this positive statistic.


Causes of Dengue Fever Infection

Dengue fever is caused by infection with one of four dengue virus strains: DENV-1, DENV-2, DENV-3, or DENV-4. These viruses are transmitted through the bite of Aedes aegypti mosquitoes. When an infected mosquito bites a person, the virus enters the bloodstream and causes infection.  Several strains of the dengue virus circulate, and children can be infected multiple times throughout their lives. This can sometimes lead to more severe symptoms with subsequent infections.

Symptoms to Watch For:

  • Sudden high fever (up to 105°F or 40°C)
  • Headache
  • Muscle and joint pain
  • Nausea and vomiting
  • Red rash or spots in the abdomen, arms and leg, and blackened stools
  • Fatigue

Diagnosis and Treatment:

Dengue fever is diagnosed based on symptoms and medical history, with potential blood tests for confirmation. There’s no specific cure, but treatment focuses on supportive measures like rest, fluids, pain relievers, and fever reducers. In severe cases, hospitalization may be necessary.

Prevention Measures:

The best overall prevention method is to avoid mosquito bites:

  • Use insect repellent
  • Wear long-sleeved clothing and pants
  • Eliminate standing water sources around your home

If you suspect dengue fever in your child, seek medical attention immediately. Early diagnosis and treatment can significantly improve outcomes.

Early Vaccination is Key:
