“WHO has assessed the risk of dengue as high globally. What it means it requires the maximal attention and response from all levels of the organization to support countries around the world, controlling the current dengue outbreaks, and also preparing for the countries to respond to the upcoming dengue season.”

4. SOUNDBITE (English) Dr. Diana Rojas Alvarez, Team Lead on Arboviruses, World Health Organization (WHO):
“The main drivers of dengue transmission are mostly social and environmental factors. So, unplanned urbanization, population growth, and other factors that are related with the globalization process are part of the transmission dynamics of dengue. Climate change has an impact on dengue transmission because it increases rainfall, humidity, and temperature. So, these mosquitoes are very sensitive to temperature.”

6. SOUNDBITE (English) Dr. Diana Rojas Alvarez, Team Lead on Arboviruses, World Health Organization (WHO):
“Mosquitoes can thrive in more countries because of increasing temperatures due to climate change. Many more countries are reporting cases. About 4 billion people are at risk of becoming infected with the dengue virus, but most people won't get any symptoms. But for those who do, they will recover within 1 to 2 weeks.”

8. SOUNDBITE (English) Dr. Diana Rojas Alvarez, Team Lead on Arboviruses, World Health Organization (WHO):
“Since the beginning of this year, over 5 million cases and about 5,000 deaths of dengue have been reported worldwide, and close to 80 percent of those cases have been reported in the Americas, followed by Southeast Asia and the Western Pacific. The distribution of the mosquitoes that transmit dengue and other mosquito-borne viruses have changed in the last few years due to several social and environmental factors.”

“It is also concerning that dengue outbreaks are occurring in fragile and conflict-affected countries in the eastern Mediterranean region such as Afghanistan, Pakistan, Sudan, Somalia, Yemen.”

“Usually, Europe reports imported cases from the Americas, from the Western Pacific, from the endemic regions. But this year, we saw limited clusters of autochthonous transmission. As we know, the summers are getting warmer, and there are two main vectors of this virus. One is the Aedes aegypti mosquito, which is widely distributed in Europe and is called the tiger mosquito.”

The UN World Health Organization (WHO) said today (22 Dec) that this year's surprising spike in dengue infections globally represents a potentially high public health threat.
The warning came as WHO reported more than five million dengue infections and 5,000 deaths from the disease worldwide this year.
Briefing journalists on Friday at the UN in Geneva, Dr. Diana Rojas Alvarez, WHO Team Lead on Arboviruses, said that the threat required “the maximal attention and response from all levels” of the UN health agency to support countries in controlling current dengue outbreaks and prepare for the upcoming dengue season.
Dengue is the most common viral infection transmitted to humans bitten by infected mosquitoes.
It is mainly found in urban areas within tropical and sub-tropical climates.
The rise in reported dengue cases in more countries is explained by the fact that infected mosquitoes now thrive in more countries because of global warming associated with rising emissions.
“Climate change has an impact on dengue transmission because it increases rainfall, humidity, and temperature,” said Dr. Alvarez.
“These mosquitoes are very sensitive to temperature.”
Although four billion people are at risk from dengue, most of those infected are symptom-free and usually recover within one to two weeks.
However, according to WHO, severe dengue infections are marked by shock, severe bleeding, or severe organ impairment.
It also highlighted that these dangerous symptoms often start “after the fever has gone away,” catching carers and medical professionals unaware.
Warning signs to look out for include intense abdominal pain, persistent vomiting, bleeding gums, fluid accumulation, lethargy, restlessness, and liver enlargement.
As there is no specific treatment for dengue, early detection and access to proper medical care are crucial to lower the probability of dying due to severe dengue.
“Since the beginning of this year, over five million cases and about 5,000 deaths of dengue have been reported worldwide and close to 80 percent of those cases have been reported in the Americas, followed by Southeast Asia and the Western Pacific,” reported Dr. Alvarez.
She added that “it is also concerning that dengue outbreaks are occurring in fragile and conflict-affected countries in the eastern Mediterranean region such as Afghanistan, Pakistan, Sudan, Somalia and Yemen.
The global prevalence of mosquitoes has changed in the last few years owing to the 2023 El Niño phenomenon, which accentuated the effects of global warming temperatures and climate change, WHO said.
Both factors are associated with previously dengue-free countries such as France, Italy, and Spain reporting infections that originated at home – so-called autochthonous transmission - rather than abroad.
The disease vector is the Aedes aegypti mosquito, widely distributed in Europe and more commonly known as the “tiger mosquito.”
“Usually, Europe reports imported cases from the Americas, from the Western Pacific, from the endemic regions,” said Dr. Alvarez.
“But this year, we saw limited clusters of autochthonous transmission. As we know, the summers are getting warmer”.
