Understanding Dengue Fever: Prevention, Treatment, and the Role of Orange County Mosquito Services

What is Dengue Fever?

Dengue fever is a mosquito-borne viral infection that primarily affects tropical and subtropical regions.

Caused by four distinct serotypes of the dengue virus (DENV-1, DENV-2, DENV-3, and DENV-4), the virus is spread through the bite of an infected Aedes mosquito, particularly the Aedes aegypti species.

Dengue fever is a global concern, with an estimated 390 million infections occurring annually worldwide, leading to significant morbidity and mortality.

Symptoms of Dengue Fever

Symptoms of dengue fever typically appear 4-10 days after an infected mosquito bite and can range from mild to severe:

• Sudden onset of high fever (up to 105°F)
• Severe headache
• Pain behind the eyes
• Muscle and joint pain
• Nausea and vomiting
• Rash (may appear 2-5 days after fever onset)
• Fatigue

Severe Dengue Fever (Dengue Hemorrhagic Fever / Dengue Shock Syndrome)

In some cases, dengue fever can progress to severe forms, known as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS).

DHF is characterized by bleeding, while DSS is a more severe form that can lead to organ failure and shock.

Warning signs of severe dengue include:

• Severe abdominal pain
• Persistent vomiting
• Bleeding from the nose, gums, or under the skin
• Rapid breathing
• Cold, clammy skin

Treatment for Dengue Fever

There is no specific antiviral treatment for dengue fever.

Treatment focuses on managing symptoms and preventing complications, including:

• Rest
• Pain relievers (e.g., acetaminophen, ibuprofen)
• Fluids to prevent dehydration
• Hospitalization in severe cases

Prevention of Dengue Fever

Preventing dengue fever involves reducing the risk of mosquito bites:

• Use insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus
• Wear long sleeves and pants when outdoors
• Use mosquito nets over beds
• Eliminate standing water where mosquitoes can breed (e.g., bird baths, clogged gutters)
