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, travelers to popular destinations like Brazil and India could contract the disease. The virus is also known as ‘breakbone fever’ due to its symptoms. What Are The Symptoms of Dengue? Unlike other diseases, dengue has different symptoms depending on the stage it is in. According to the Centers for Disease Control, 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: Centers for Disease Control 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. What Is Dengue Hemorrhagic Fever? 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. How Does Dengue Spread? 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 CDC, 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.

I was impressed that the RN talked to through all the potential health risks of going to Thailand including dengue (which I didn’t know as a problem). It was informative and helpful. The actual vaccines were administered quickly and painlessly. I was also happy to buy the right kind of mosquito repellant right there in the office. I will definitely return if I need travel vaccines in the future.” Submitted by: Sari ★★★★★ “I learned a lot!““Sheila was extremely friendly and very knowledgeable. I learned a lot about keeping my son free from disease for his trip to South Africa. She even noticed a series of vaccinations he received as an infant that were not given within the appropriate intervals. I will definitely recommend this clinic to others! I also was able to purchase a kit to keep my son safe from being bit by mosquitoes.” Submitted by: Sherolyn How Is Dengue Treated? 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. Is There A Dengue Vaccine? Looking For the Dengue Vaccine? The 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 the United States. 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 the United States.
