Puerto Rico has declared a public health emergency as the number of dengue fever cases continues to rise, with a total of 549 cases recorded so far this year, according to officials. The majority of these cases have been reported in the capital city of San Juan, highlighting the urgent need for targeted measures to combat the spread of the disease.

The Puerto Rico Department of Health has revealed a significant increase in dengue cases compared to the same period last year, with a staggering 140% rise from January 1 to March 21. Dr. Carlos Mellado López, the Secretary of the Puerto Rico Department of Health, expressed concerns over the surpassing of historical figures for dengue cases this year, emphasizing that the increase is not limited to Puerto Rico alone but is also observed throughout the region of the Americas.

In response to the worsening situation, the health department has outlined a comprehensive plan aimed at early detection, epidemiological surveillance, and educational initiatives on dengue prevention and control. Municipalities have also been called upon to play an essential role in combating the disease by fostering community participation in efforts to eliminate mosquito breeding grounds.

According to the Centers for Disease Control and Prevention (CDC), dengue viruses are transmitted through the bites of infected Aedes species mosquitoes, predominantly found in tropical and subtropical regions. These mosquitoes are also responsible for spreading other viruses such as Zika and chikungunya. The CDC further highlights that there are no specific medications to treat dengue, and supportive care is the primary form of treatment, including rest, hydration, and the use of acetaminophen.

While dengue symptoms are often mild, including fever, rash, nausea, vomiting, and muscle and joint pain, about one in four people can experience symptoms lasting up to seven days. However, it is crucial to note that symptoms can be easily confused with other illnesses, complicating early diagnosis. Although fatalities are rare, severe cases of dengue can lead to organ damage, internal bleeding, and shock, affecting approximately one in twenty individuals.

Fortunately, Puerto Rico has an approved dengue vaccine for children aged 9 to 16 who have previously been diagnosed with a dengue virus infection and reside in endemic areas. The vaccine is currently included in the territory's routine childhood immunization schedule.

The alarming surge in dengue cases in Puerto Rico demands a swift and coordinated response from health authorities, municipalities, and the public in order to effectively control the spread of the disease. By raising awareness, implementing preventive measures, and providing support to affected communities, Puerto Rico aims to curb the increasing impact of dengue fever on its population.
