In some cases, symptoms worsen and can become life-threatening. Blood vessels often become damaged and leaky. And the number of clot-forming cells (platelets) in your bloodstream drops. This can cause: Bleeding from your nose and mouth Severe abdominal pain Persistent vomiting Bleeding under the skin, which might look like bruising Problems with your lungs, liver and heart. If you are living or traveling in tropical areas where dengue fever is common, these tips may help reduce your risk of mosquito bites: Stay in air-conditioned or well-screened housing. It's particularly important to keep mosquitoes out at night. Reschedule outdoor activities. Avoid being outdoors at dawn, dusk and early evening, when more mosquitoes are out. Wear protective clothing. When you go into mosquito-infested areas, wear a long-sleeved shirt, long pants, socks and shoes. Use mosquito repellent. Permethrin can be applied to your clothing, shoes, camping gear and bed netting. You can also buy clothing made with permethrin already in it. For your skin, use a repellent containing at least a 10 percent concentration of DEET. Reduce mosquito habitat. The mosquitoes that carry the dengue virus typically live in and around houses, breeding in standing water that can collect in such things as used automobile tires. Reduce the breeding habitat to lower mosquito populations.....
