Where Does Dengue Fever Occur?

Dengue fever is a mosquito-borne virus affecting more than 390 million people each year. While the disease is generally mild, it can be deadly.

Recent research shows dengue is between 100 and 800 years old. It likely originated in Africa or Southeast Asia and was then carried to other parts of the world through travel and trade.

In recent years, dengue has spread to over 100 countries. Now, travellers to popular destinations like Brazil and India could contract the disease.

The virus is also known as ‘breakbone fever’ due to its symptoms.

Unlike other diseases, dengue has different symptoms depending on the stage it is in. According to the PHAC, dengue’s most common symptoms are:

Dengue Fever Symptoms

Typical Symptoms Dangerous Symptoms
High Fever Severe Abdominal Pain
Severe Headache Persistent Vomiting
Severe Eye Pain Red Spots or Patches On Skin
Joint Pain Vomiting Blood
Muscle and/or Bone Pain Black, Tarry Stools
Rash Drowsiness or Irritability
Easy Bruising, Mild Nose or Gum Bleeding Pale, Cold or Clammy Skin
Low White Cell Count Difficulty Breathing

Source: PHAC

The virus can show symptoms quickly. Fever, headache, joint pain and bleeding can last for up to seven days.

Generally, younger children and those experiencing their first dengue infection have milder symptoms. It is possible to contract dengue more than once.

To learn more about the signs and symptoms of dengue fever, contact a Passport Health Travel Specialist. Call or book an appointment online.

Serious cases of dengue will progress into dengue hemorrhagic fever or DHF. While dengue is generally ‘flu-like’ DHF can be fatal.

Early symptoms are the same as dengue. But, acute symptoms are more serious. The virus causes ‘leaky’ blood vessels, circulatory failure, shock and death.

There is no cure for dengue nor dengue hemorrhagic fever.

Like its cousins chikungunya and Zika, the dengue virus spreads through mosquito bites. Dengue often spreads when:

  • A mosquito (usually of the Aedes species) bites an infected human.
  • This mosquito is now infected with dengue fever. Mosquitoes are only carriers of the disease, it does not affect them as it does humans.
  • The mosquito bites a human. That human is now infected with the virus. He or she will then infect any unaffected mosquitoes that bite them.

According to the PHAC, about 75 percent of all dengue infections show no symptoms. Around 20 percent of dengue symptoms are mild. But, five percent will develop severe, life-threatening symptoms.

Be sure to use repellents and nettings to avoid mosquito bites.

“Thorough & informative“
“The staff was friendly, skilled and thorough. I took my family of six- my 4 teenagers said it was the quickest & most painless vaccination they’ ve ever had! It was very informative – what to avoid and also how to best protect ourselves when ordering food & drinks, sun screen for the beach and mosquito repellent for dengue in the area. Great for children to hear and understand from a professional!”

I would highly recommend this clinic.”

“Good service“
“A good place to start when you want to travel and be safe. They have all the information on local diseases and helped us stay dengue-free for our trip.”

Submitted by: Rose

There is no specific antiviral treatment for dengue. Supportive care is used to help with symptoms. Usually, analgesics, hydration and bed rest are enough to help patients through their infection. If you suspect dengue during or after you trip, be sure to seek medical attention.

Because of the lack of a true dengue treatment, prevention is key while in regions with the disease.

Looking For the Dengue Vaccine?

Dengue vaccination is keyThe Future of Dengue Prevention

Visit our dengue vaccine page to learn more.

One dengue vaccine, Dengvaxia has been approved for use in some countries. But, it is not yet available in Canada. This dengue vaccine has proven effective in tests conducted in Asia and Latin America.

Other dengue vaccines are in various trial stages throughout the world. This includes DENVax (Phase II trials), TDENV PIV (Phase II study) and V180 (Phase I stage). There is no timetable for when, or if, these vaccines will be available in Canada.

As of now, the best form of dengue protection for Canadian travellers is through preventing mosquito bites.

As a mosquito-borne disease, preventing dengue is as simple as preventing mosquito bites. There is no approved dengue vaccine in Canada.

Many health organizations suggest the following to protect yourself from dengue:

  • Wear long-sleeve shirts and long pants.
  • Treat clothes with repellents like permethrin.
  • Use EPA-registered mosquito repellent like DEET.
  • Consider using mosquito netting if you will be in an areas with many mosquitoes.
  • Make sure windows and doors screens are closed to avoid allowing mosquitoes into inclosed spaces.
  • Avoid areas with standing water. Especially at times of high mosquito activity like dawn and dusk.

Paspsort Health locations carry kits specifically designed to help prevent mosquito bites and mosquito-borne disease. Be sure to take one with you on your next trip.

For more information on mosquito bite prevention methods and what you can do to protect yourself and your family, speak with a travel health specialist by calling or booking online today.

Before 1970, dengue outbreaks were not common. Only nine countries had experience severe dengue epidemics. Since then, the disease has spread almost globally. An estimated 3.9 billion people are at risk of dengue infection in 128 countries. The countries and regions most affected by dengue fever include:

  • Southeast Asia – Myanmar, India, Indonesia
  • Western Pacific – Cambodia, Malaysia, Philippines
  • South Cone – Argentina, Brazil (This region accounts for 64.6% of all dengue cases in the Americas.)
  • Andean Mountains – Colombia, Ecuador, Peru
  • Central America – Costa Rica, Honduras
  • Caribbean Countries – Barbados, Cuba, Dominican Republic
  • North America – Mexico, Southern United States
  • Africa – Various portions of the continent have different levels of infections. But, it is generally less than Asia or the Americas.
  • Eastern Mediterranean – Egypt, Israel, Libya
