In Canada, there is presently no licensed vaccination for dengue fever. Travelers to dengue-prone areas should take precautions against mosquito bites, whether outside or inside buildings. These include using insect repellent, wearing long-sleeved shirts and pants, and installing screening on windows and doors. Dengue vaccines are under development but not yet available for use in humans. For now, the best defense against dengue is awareness of the symptoms and prevention of mosquito bites. If you do come into contact with a mosquito that has bitten an infected person, take appropriate action by removing its body part where it attaches itself (usually by squeezing hard), and call your doctor. Dengue is a viral disease spread by mosquitoes. Symptoms include fever, muscle pain, headache, nausea, vomiting, diarrhea, eyesight problems, and skin rash. Most people recover from dengue within a week to 10 days, but some may experience severe complications such as plasma leakage leading to severe hemorrhaging or death. There is no cure for dengue infection at this time. Anyone who will be traveling to countries where dengue is found should learn about the risk factors and take measures to prevent being bitten by mosquitoes. Dengue is found in more than 100 countries around the world.
