United States: The Centers for Disease Control and Prevention – also known as CDC, has recently issued warning against the sudden spread of dengue fever infections across the United States. The warning has been issued to advise the health care providers and general public.

According to the official data presented by the CDC, across the nation around 2,241 people have been infected from the viral disease – which spreads through mosquito bites – in 2024.

High Dengue Fever Cases Reported in Several States!

According to the official reports, the high number of cases have been found in Florida, New York and Massachusetts. Along with this, the horrifying number of cases were reported in Puerto Rice, nearly 1,500 during this year. Health emergency (due to dengue) was issued by the US territory this March, whereas an emergency was declared by the World Health Organisation (WHO) last December, according to Time.

Summers give a push to the spread of the disease!

The health experts have mentioned that the spread of the infection has been exacerbated due to El Niño effect – which is responsible for wet and warm summer months. They have also outlined that the current climate is favorable for mosquitoes to breed and reproduce, continuing the spread of the infection.

The official statistics explain that as many as 400 million people get infected with dengue annually, as mentioned by Time.

Understanding Dengue

Dengue, a viral malady predominantly encountered in tropical and subtropical zones, is delineated by the World Health Organization (WHO) as having four distinct viral strains.

The Aedes species mosquitoes, when infected, serve as vectors transmitting this ailment to humans. While numerous individuals endure mild or asymptomatic cases, others grapple with afflictions such as aches, nausea, rashes, and emesis. An elevated temperature is also a hallmark of dengue. WHO notes the incubation period to be approximately 4-10 days post-infection, whereas the Centers for Disease Control and Prevention (CDC) suggests a wider span: within two weeks of a mosquito bite.

Typically, symptoms abate within a week, as stated by the CDC.

Dengue can be fatal if severe symptoms are observed by an individual, including abdominal pain, persistent vomiting, bleeding gums or nose, fatigue, bloody stools, pale and cold skin, and more.

Preventive Measures Against Dengue

In the United States, the preponderance of cases are traced back to travelers visiting dengue-prone regions. Nonetheless, given that the mosquitoes capable of spreading this virus are pervasive nationwide, “local transmission of dengue is feasible,” according to the CDC.

To thwart contracting dengue, avoiding mosquito bites is paramount. This can be achieved through the application of insect repellents or donning loose, long-sleeved attire, as per Time.

Dengue epidemics typically recur every two to five years. Travelers to Latin America, where an unprecedented surge in cases has been recorded, should exercise heightened vigilance.

Addressing Dengue

Physicians predominantly manage dengue symptoms by prescribing acetaminophen and advising patients to maintain hydration. There is no specific medication to circumvent the illness.

A dengue vaccine is available for children aged 9 to 16 who have verified prior infections or reside in dengue-endemic areas. The CDC endorses vaccination within US territories.

In light of new advisories, medical practitioners are urged to be cognizant of the rising incidence of dengue and to consider diagnostic testing where warranted.

Is dengue common in the United States?

According to the recently released list by CDC, dengue transmission is “frequent or continuous” in freely associated states and six US territories. The spread is commonly seen in Puerto Rico, US Virgin Islands and American Samoa, as reported by Time.

Within the US states, Florida has reported around 197 cases, New York and Massachusetts reported around 134 and 50 cases, respectively. As per CDC, the transmission of virus is also commonly reported in Arizona and California.
