That is really poor luck, but if you are determined to keep away from all risk of dengue fever, you will have to cross more than a hundred nations off your list of areas to go. Dengue fever is a tropical virus infection spread by mosquitoes that bite for the duration of the day as effectively as for the duration of the night. It happens in a lot of elements of Asia, Africa and Latin America, the islands of the Caribbean, the Pacific and even the northernmost tip of Australia, and the southern reaches of the United States. Signs typically seem 5 to eight days soon after the infective bite with a sudden onset of fever and headache, with severe joint and muscle ache. Signs and symptoms may possibly persist for about 7 to 10 days in complete, however at times significantly longer. Dengue fever is normally an uncomplicated illness that needs only symptomatic treatment method. However, a subsequent infection with dengue viruses can result in critical problems that want specialised treatment method.
Building a excellent, risk-free, successful vaccine is a extremely higher priority, but in the meantime, cautious precautions actually do lessen the danger: cover up at occasions when mosquitoes are biting, use lots of DEET-based insect repellent on clothing and exposed skin and use mosquito coils, spray, a plug-in insect killer or a mosquito net at night. This kind of precautions must be schedule for all tropical travellers, not just simply because of the risk of dengue but to avert a wide assortment of other insect-borne illnesses. My advice: adhere to these precautions cautiously, and don’t cancel your trip.
