CDC Warns of Dengue Fever Risks in Over 15 Countries
The U.S. Centers for Disease Control and Prevention (CDC) has issued a warning regarding dengue fever in more than 15 countries. This notice, categorized as a “Level 1: Please take normal precautions,” was made public on Monday.
Dengue fever presents a year-round risk in various regions of the world. Outbreaks generally happen every two to five years, and some countries are now seeing an uptick in the number of cases.
This warning coincides with the ongoing spring break travel period for many Americans, affecting destinations like the Maldives and New Zealand’s Cook Islands.
Dengue fever is caused by a virus, transmitted through infected mosquito bites. The CDC notes that typical symptoms include pain, nausea, vomiting, and a rash.
The illness is often found in tropical and subtropical areas around the globe. It’s especially prevalent in many regions of the Americas, Africa, the Middle East, Asia, the Pacific Islands, and the Caribbean.
Symptoms and Treatment
Typical symptoms generally emerge within two weeks of being bitten and can include pain—often experienced in the eyes, muscles, joints, and bones—as well as nausea, vomiting, and a rash. Most individuals recover within two to seven days after showing symptoms.
While dengue fever is frequently mild, it can escalate to severe cases, leading to complications like headaches, joint pain, abdominal pain, and even death in extreme situations. Dr. Mark Fisher from International SOS has noted that about 1 in 20 people with a fever will develop severe dengue.
Severe dengue can result in serious symptoms such as bleeding from the nose or gums and vomiting blood, prompting the need for medical attention. Currently, there are no specific medications to treat dengue fever, so those infected are typically advised to rest and hydrate and use acetaminophen for pain relief.
A vaccine is available, but it’s only recommended for U.S. children aged 9 to 16 who have previously tested positive for dengue and reside in endemic areas.
Prevention of Mosquito-Borne Diseases
Travelers returning from regions where dengue is endemic should take precautions to avoid mosquito bites for three weeks. Anyone developing symptoms within two weeks after returning should seek medical evaluation.
Experts emphasize the importance of eliminating any standing water around homes, which is a breeding ground for mosquitoes. This includes things like buckets, small containers, and planters.
According to Fisher, using insect repellents containing DEET or other recommended compounds can be very effective. Wearing long-sleeved clothing, especially during dawn and dusk, can also reduce exposure to mosquito bites.
Keeping windows and doors screened is an effective way to block insects and minimize health risks. Fisher also recommends using mosquito nets while sleeping and eliminating any standing water in and around living spaces.
