Dengue fever is a disease caused by a virus that is transmitted by mosquitoes. It is a serious health concern for travelers to certain areas of the world, including Latin America, the Caribbean, the Middle East, Southeast Asia and the South Pacific. Dengue fever can cause a number of uncomfortable symptoms, including fever, headache, joint pain, rash and other body aches. In more severe cases, it can lead to more serious complications, such as bleeding, organ failure and even death.
Travelers can reduce their risk of getting infected with dengue fever by taking steps to protect themselves from mosquito bites. Whenever possible, travelers should try to stay in air-conditioned areas or in rooms that are well screened against mosquitoes. It is also important to wear long-sleeved shirts and long pants, especially during dusk and dawn when mosquitoes are more active. Effective insect repellents that contain DEET should be applied to any exposed skin. Clothing can also be treated with insect repellent, as well as tents and mosquito netting if they are available.
If travelers do get infected with dengue fever, they should be sure to drink plenty of fluids and get plenty of rest, as dehydration can increase the severity of the illness. Over-the-counter pain medications, such as ibuprofen, can help reduce fever and alleviate some of the uncomfortable symptoms. However, it is important to avoid taking aspirin and other non-steroidal anti-inflammatory drugs, as these may worsen the bleeding tendency associated with dengue fever. If symptoms become more severe or if travelers are unable to control their fever, they should seek medical attention as soon as possible.
Because of the serious nature of dengue fever, travelers should be aware of the risk for infection when traveling to areas known to be endemic for dengue fever. They should take steps to minimize mosquito bites and, if they become ill, seek medical care promptly. Staying aware of the danger and acting appropriately can help travelers safeguard their health while traveling.
