The Centers for Disease Control and Prevention (CDC) has issued an alert concerning an increase in dengue fever cases in several popular destinations for spring break vacations. This rise of dengue fever, a mosquito-borne ailment, could potentially affect countless travelers.
Dengue fever is commonly found in parts of the Caribbean, Central America, and South East Asia. The CDC’s recent report highlighted a significant rise in cases in these areas. While Dengue is not typically life-threatening, it can cause severe flu-like symptoms, lasting up to a week, which could potentially disrupt travel plans, according to the CDC.
The agency advised travelers to protect themselves from mosquito bites by using insect repellent, wearing long sleeves and pants, and staying in locations with air conditioning or window and door screens whenever possible. The CDC also stressed the importance of medical attention if symptoms such as fever, severe headache, pain behind the eyes, joint and muscle pain, rash, or mild bleeding occur after traveling.
The World Health Organization (WHO) has reported that the incidence of Dengue has increased 30-fold over the last 50 years. The global health body continues to work on developing a vaccine to tackle the disease, with efforts boosted by recent advancements in Dengue virus research.
The CDC advised that travelers can further minimize their chances of contracting the disease by avoiding water-filled containers, a common breeding site for the Aedes aegypti mosquito that transmits the virus. The Aedes mosquitoes are daytime biters, so travelers are encouraged to be vigilant even during daylight hours, according to the CDC.
The CDC’s warning comes as a timely reminder, given the upcoming spring break period, a popular travel-time for students and families alike. With increasing cases of Dengue fever in hot-spot destinations, travelers are urged to take necessary precautions to protect their health while enjoying their holiday.
As no specific treatment exists for the disease, timely recognition and supportive treatment can substantially lower the risk of medical complications and death. Travelers are also urged to consult with a healthcare provider before and after travel, especially if they exhibit symptoms of the disease.
