CDC Issues Health Advisory for Rising Dengue Cases in the Americas

There are many reasons to look forward to summertime, from beach weather to planning the perfect getaway. Then, there are those pesky mosquitoes that try to land on you, ruining all the fun. As if the swat, itch, and scratch routine weren’t enough of a nuisance, Americans have something else to look out for during the summer season ― dengue, a virus that spreads through mosquito bites.

The Centers for Disease Control and Prevention (CDC) has issued a health advisory warning due to the increase in dengue virus infections this year. From Jan. 1 to June 24 this year, countries in the Americas have reported over 9.7 million dengue cases, double the 4.6 million cases reported in 2023. As of June 24, 745 cases were reported among U.S. travelers. Globally, the numbers are on the rise. Almost half of the world lives in areas with a risk of dengue.

Dengue is a viral disease caused by any of the four related viruses: dengue 1, 2, 3, and 4. Transmission is common in parts of the world with tropical and subtropical climates.

The CDC classified the following six U.S. territories and freely associated states as areas where dengue transmission is frequent. There have been 16 cases of dengue reported in North Carolina so far in 2024, including cases in Buncombe, Transylvania, and Jackson counties.

One in four individuals with dengue will get sick. Symptoms may include aches and pains, nausea, vomiting, rash, and warning signs such as belly pain, bleeding from the nose or gums, and feeling irritable or tired.

Although there is no specific medicine to treat dengue, the CDC recommends resting, taking acetaminophen to control fever, and staying hydrated. Seek medical attention if you have a fever.

Severe dengue is a medical emergency. Immediately visit a local clinic or the emergency room if you or a family member experience severe symptoms such as belly pain, bleeding, or vomiting.

Dengue hemorrhagic fever is a severe stage of the virus with symptoms that may lead to internal bleeding and circulatory system failure. If left untreated, it can be fatal.

Prevent dengue by reducing mosquito breeding sites, keeping mosquitoes outside, wearing insect repellent, avoiding exposure during peak mosquito biting times, and covering up with long-sleeved clothing.

There is currently no approved vaccine to prevent dengue, but multiple trials are underway to develop an effective vaccine.
