Scientists link climate change to dengue outbreaks, develop early warning system   

by Chief Editor
written by Chief Editor

Understanding the Climate-Dengue Connection

The intricate relationship between climate variables—including temperature, rainfall, and humidity—and the incidence of dengue fever has recently come under the spotlight. A study conducted by researchers Sophia Yacob and Roxy Mathew Koll from the Indian Institute of Tropical Meteorology (IITM), Pune, dives into how these elements affect dengue transmission in one of India’s major hotspots. The findings suggest a strong link between moderate temperatures, specific rainfall patterns, and increased dengue cases.

What Makes Pune a Dengue Hotspot?

During the monsoon season in Pune, where temperatures hover between 27–35 degrees Celsius, conditions become ideal for the dengue virus to thrive. These temperatures influence mosquito life cycles and the development rate of the virus within them. Additionally, a humidity range of 60 to 78 percent presents the perfect breeding ground for mosquitoes, as outlined by the study. Distinguishing Pune, the research finds the need for region-specific climate-dengue studies due to varying local climatic factors.

Role of Rainfall in Dengue Transmission

According to the study, moderate to heavy rainfall plays a dual role in dengue transmission. Continuous rainfall, up to 150 mm in a week, can lead to stagnant water pools—ideal breeding sites for mosquitoes. Conversely, heavy rainfall exceeding 150 mm a week can wash away mosquito eggs and larvae, thereby reducing outbreaks. This pattern accentuates the significance of rainfall distribution—not just quantity—on dengue prevalence. The India Meteorological Department (IMD) anticipates rainy patterns through active and break phases, which, if monitored, can enhance early dengue warnings.

Advancements in Predictive Modeling

Researchers have leveraged artificial intelligence and machine learning to devise a predictive model that can forecast dengue outbreaks over two months in advance. This advancement offers local authorities a crucial head start to prepare and mitigate the disease’s impact effectively. With temperature and humidity projections indicating a rise and more erratic monsoon patterns, this model could become an essential tool in dengue management strategies.

Fast-Forwarding to the Future: Climate Change and Dengue

Future trends in climate projections show a worrying increase in average temperatures, which could enhance dengue transmission across various Indian states. Situations aligning with increased temperatures and humidity forecast a heightened dengue risk despite potential heavy rainfall events. Under scenarios of both low and high fossil fuel emissions, Pune’s temperature could escalate by 1.2 to 3.5 degrees Celsius by century’s end.

Collaboration as a Key to Success

“Our study underscores the power of interdisciplinary collaboration,” noted researcher Roxy Mathew Koll. The integration of meteorological data and the cooperation of health departments are pivotal in building comprehensive early warning systems. Sujata Saunik, Maharashtra’s Chief Secretary, echoes this sentiment, emphasizing the importance of such collaborations in tackling complex climate-health challenges. Improved synergy could equip states like Kerala, Maharashtra, and others with regions already burdened by high dengue incidence with robust preparedness plans.

FAQs on Climate and Dengue Connection

  • What temperature range is most conducive to dengue transmission?
    Temperatures above 27 degrees Celsius, particularly between 27 and 35 degrees Celsius, are most conducive during the monsoon period.
  • How does rainfall affect dengue transmission?
    Moderate, spread-out rainfall promotes mosquito breeding, while very heavy rainfall can wash away breeding sites.
  • What are the benefits of predictive modeling for dengue?
    Early prediction models provide authorities critical time to launch preventative strategies to mitigate dengue outbreaks.

Did You Know?

The intricate workings of a mosquito’s life cycle are directly impacted by temperature changes. Warmer weather not only decreases their lifespan but also expedites the maturation of the dengue virus within the mosquito.

Pro Tip: Stay Informed, Stay Prepared

Regularly check the India Meteorological Department’s forecasts for active-break cycles to better anticipate and distinguish the periods of high and low dengue risk.

Shortage and High Demand for Dengue Vaccines

by Chief Editor
written by Chief Editor

"Scarcity and High Demand for Dengue Vaccines: A Growing Concern"

The current outbreak-news/item/2024-DON518″ title=”Dengue – Global situation – World Health Organization (WHO)”>dengue outbreak, the worst in the last 15 years, has sparked a surge in vaccination inquiries. In La Plata, the vaccine for private individuals costs around $103,000 per dose, and demand has outstripped supply, making it scarce in pharmacies.

The national plan for dengue prevention prioritizes individuals between 15 to 59 years old who have had the disease and are registered in the Argentine Health Information System. However, pharmacists report that the vaccine has been unavailable for months due to a lack of delivery from Takeda, the manufacturing laboratory.

Introduced in Argentina, the Qdenga vaccine is distributed in over 14,000 pharmacies and clinics nationwide. It protects against all four dengue serotypes and requires two doses, spaced three months apart. Unlike some other vaccines, no prescription is needed.

As of December 31, 2023, Tucumán led the way in vaccinations with 95,000 doses, followed by Santa Fe with 60,000, and Buenos Aires with nearly 53,000. In La Plata, 89 pharmacies, along with four in Ensenada and nine in Berisso, participate in the provincial vaccination campaign.

The Buenos Aires Ministry of Health reported that, by the end of 2023, 52,577 people received doses, reaching 34% of the campaign’s target. Between June and December 2023, 2,720 compatible cases were reported, with 19 confirmed—an increase of 216 compared to the first half of the year.

While the vaccine is not suitable for everyone, as it has certain contraindications, it plays a crucial role in reducing dengue transmission. Medical professionals advise against self-medicating for symptoms, as vasodilators like ibuprofen can worsen the condition. Instead, seek medical advice for diagnosis and direction.

With the dengue epidemic showing no signs of abating, ensuring access to vaccines and proper medical care remains a pressing concern.

written by Chief Editor

Headline: Dengue Vaccine Shortages Heighten Concerns in Santa Fe, Argentina; Mosquito Sterilization Technique Trialed Amidst Increasing Cases

Article:

In an effort to combat the escalating dengue threat, the Municipality of Santa Fe has initiated a schedule of fumigation across plazas and bustling public spaces in the city. However, the provincial government’s worry has been exacerbated by the acute shortage of second doses of dengue vaccines in pharmacies. This deficiency could potentially compromise the immunization of those who have already started their vaccination schedules.

The recent influx of rain in Santa Fe has fostered optimal conditions for the breeding of the Aedes aegypti mosquito, essential to its life cycle. Yet, farmacias have been receiving insufficient vaccine doses for nearly three months’, with only a small fraction reaching them, according to the College of Pharmacists in Santa Fe. They express their ongoing struggle to meet the high demand, with an ambiguous assurance of a potential normalcy resuming in January.

While the Ministry of Health has refuted the risk of extended intervals between doses, public health experts caution that a prompt vaccination schedule is crucial. In Santa Fe city alone, 4,088 dengue cases have been reported between November 2023 and April 2024, with estimated total cases in the province reaching over 60,000.

To tackle this mosquito-borne threat, the Commission Nacional de Energia Atomica (CNEA) has been investigating a novel technique: Insect Sterilization. Recent trials involved the release of 25,000 fluorescently labeled, sterilized male mosquitoes in Ezeiza’s Barrio Uno. This Technique, which involves raising and irradiating male mosquitos to reduce fertility, holds promise in combating dengue.

As dengue cases continue to escalate, addressing vaccine shortages and exploring innovative mosquito control methods become essential in mitigating the health risks posed by this preventable disease.

Dengue Vaccine Shows Positive Safety and Efficacy Profile, Says Sáez-Llorens

by Chief Editor
written by Chief Editor

Title: Panama’s Health Ministry Halts Dengue Vaccine Acquisition, Citing Lack of Robust Evidence and High Efficacy Threshold

The Ministry of Health (Minsa) in Panama has decided not to acquire the dengue vaccine, Qdenga (TAK-003), at this time. The ministry cited two primary reasons for this decision. First, Minsa stated that there is not yet sufficient evidence demonstrating the vaccine’s effectiveness against the four circulating dengue virus serotypes in Panama. Secondly, the ministry is waiting for a vaccine with at least 90% to 95% efficacy against all four serotypes before proceeding, and will continue to monitor the recommendations of the World Health Organization (WHO) and the Pan American Health Organization (PAHO).

Qdenga: A Promising Vaccine

Qdenga, developed by Japanese pharma giant Takeda, was evaluated in Panama by a team of scientists at the Cevaxin research center. The clinical trials involved 3,000 local volunteers and lasted for five years. The vaccine demonstrated safety and efficacy in the Panamanian population, according to Dr. Xavier Sáez-Llorens, an infectologist, pediatrician, and clinical researcher at Cevaxin.

While acknowledging that many vaccines in use globally, such as BCG, pertussis, influenza, and malaria, do not exceed 90% efficacy, Dr. Sáez-Llorens highlighted their significant impact on public health by reducing hospitalizations and deaths. In this context, Qdenga could also have a relevant impact, he suggested.

The WHO has recommended the use of Qdenga in regions with a seroprevalence of 60% or more and high transmissibility, such as Panama. In the absence of seroprevalence studies, the recommendation is based on high hospitalization rates among adolescents, a current trend in Panama.

However, Qdenga is ineffective against serotype 3 in dengue-naive individuals, and data for serotype 4 is limited due to its low circulation during trials. In seropositive subjects, the vaccine is effective against all four serotypes. In Panama, serotypes 1 and 2 are most prevalent, and Qdenga has shown high efficacy against them.

Expert Opinions Divide

Dr. Sáez-Llorens believes that while Qdenga’s impact on public health might be moderate due to the need for mass immunization to maximize its effect, individual protection against hospitalization and death would be significantly elevated.

On the other hand, Dr. Javier Nieto, an infectologist and former director of the Institute Conmemorativo Gorgas de Estudios de la Salud (ICGES), criticized the ministry’s decision. He argued that even with a low efficacy rate, the widespread prevalence of dengue makes the vaccine beneficial for public health by reducing cases and potential hospitalizations.

Dr. Nieto also noted that serotype circulation can vary annually, and the vaccine’s purpose remains to reduce the disease’s specific burden. Furthermore, he emphasized the insufficiency of current disease reduction measures and the necessity of additional preventive tools.

Dengue in Panama and the Region

As of the 51st epidemiological week (December 15-21, 2024), Panama has recorded 31,605 dengue cases and 52 deaths. Over 2,600 hospitalizations have been reported, with the majority occurring in the Metro, Panama Oeste, and Colón regions.

This dengue outbreak is not exclusive to Panama. In 2024, Latin America has experienced its largest dengue epidemic since 1980, with over 12.6 million cases, 21,000 severe cases, and at least 7,700 deaths. Argentina, Brazil, Colombia, and Mexico account for 90% of these cases, with Brazil reporting the highest figures.

The dengue vaccine is available in Brazil (both public and private systems), Argentina, and Colombia (private), while several Asian countries offer it in the private sector, and some European nations provide it for travelers.

Brazil began vaccinating its population for dengue in February 2024, focusing on high-risk areas. The WHO approved the vaccine in May 2024 and recommended its use in children aged 6 to 16 in regions with high dengue prevalence. The vaccine, administered in two doses, protects against all four dengue serotypes.

written by Chief Editor

Headline: Dengue Cases Lower Than 2024 So Far, But Experts Urge Caution For Upcoming Months

Article:

In a reassuring development, infectologist Eduardo López revealed today that dengue cases this year have been significantly lower compared to the same period in 2024. However, professionals warn that the coming months may bring an increase in infections, emphasizing the importance of vaccination and prevention measures.

Early Relief, pero Cautela Necesaria

López, speaking to Radio Rivadavia, indicated that the majority of dengue cases thus far have been concentrated in the northeast of the country, particularly in Formosa and Chaco. He attributed the lower numbers in areas like Buenos Aires City and province to the delayed onset of high temperatures in December.

"This doesn’t mean we’re out of the woods," López cautioned, "February and March are historically the months with the highest dengue cases. We should wait to see how the situation evolves."

Vacunación, Una Herramienta Importante para Prevenir Dengue

Both López and infectologist Victoria Micieli, from the Conicet, expressed concern about the hesitancy among adolescents to get vaccinated against dengue. López emphasized the vaccine’s effectiveness in preventing severe cases, while Micieli stressed it as the primary preventive tool.

Micieli warned of the upcoming dengue season, saying, "Now we’re entering the hot and rainy season, which favors the reproduction of Aedes aegypti. It’s crucial to take preventive measures."

Mitos y Mitos: Eficacia de Repelentes y Resistencia al Mosquito

Addressing queries about repellent resistance, Micieli clarified that no scientific evidence supports the idea of Aedes aegypti becoming resistant to approved repellents. However, she noted ongoing research into potential resistance to insecticides like pyrethroids, used in fumigation.

Atención a las Cuatro Enfermedades del Virus del Dengue

As a reminder, dengue can present itself in four distinct forms—ranging from mild dengue fever to severe and potentially life-threatening dengue hemorrhagic fever and shock syndrome. Symptoms, which usually appear 4-10 days after infection, include fever, headache, muscle and joint pain, nausea, and skin rash.

To protect against dengue, health professionals urge the use of repellents, protective clothing, and window screens. Keep your surroundings clean to prevent mosquito breeding. Additionally, consider vaccination, especially if you live in an area with a high dengue risk. Consult your healthcare provider for personalized advice.

Low Dengue Vaccination Rates in Peru Amid Rising Cases

Peru’s Ministry of Health (Minsa) has so far administered only 45,228 doses of the dengue vaccine since the campaign began on November 23, 2023, covering just 20.30% of the targeted 222,750 children aged 10 to 16 across 16 prioritized districts in Loreto, Ucayali, Tumbes, and Piura regions. This two-dose vaccination requires a three-month interval between doses.

According to health data analyst Juan Carbajal, using the Reunis (Repositorio Único Nacional de Información en Salud), Loreto has the highest vaccination coverage at 30.24%, followed by Ucayali (22.96%), Tumbes (17.48%), and Piura (14.55%). Carbajal notes that the third week of February marks the window for administering the second dose, with Loreto leading the pace.

While vaccination progresses slowly, dengue cases are surging swiftly. Since mid-2023, cases have increased mainly in Piura, Loreto, Ucayali, San Martín, Cusco, Madre de Dios, Huánuco, Ayacucho, and Puno regions. By the end of 2024’s Week 51, Peru has reported 279,564 dengue cases and 260 deaths.

Ricardo Peña Sánchez, viceminister of Public Health, attributes the low vaccination turnout to parents’ reluctance to sign consent forms and bring their children to health facilities. He emphasizes the need for better parent engagement and education about the vaccine.

However, infection experts like Juan Carlos Celis and Antonio Quispe contend that weak communication campaigns, antivaccine groups, and insufficient prevention measures are at play. They urge the Minsa to improve communication, especially in schools, and stress the importance of the second vaccine dose for maximum protection.

Dengue symptoms include nose or mouth bleeding, abdominal pain with vomiting, fever, and general discomfort. Seek medical attention if you experience these symptoms.

Combatiendo la Epidemia de Dengue: La Lucha por la Vacunación en Perú

La epidemia de dengue más grave en tres décadas azota el Perú, con un escenario propicio para la reproducción del vector, el mosquito Aedes aegypti, gracias a las lluvias y el aumento de la temperatura, exacerbadas por el cambio climático. Según el Centro Nacional de Epidemiología, Prevención y Control de Enfermedades (CDC-Minsa), desde enero hasta el 7 de diciembre de 2024, se han registrado 256 fallecidos y 278,332 infectados, una cifra preocupante que responde a una tendencies alza desde septiembre en 13 regiones del país.

La situación es einget que el Ministerio de Salud (Minsa) ha logrado la compra de un lote de vacunas contra el dengue y, en noviembre de 2024, inició un programa piloto de inmunización en 16 distritos de las regiones más críticas: Piura, Loreto, Ucayali y Tumbes. La estrategia, que comenzó el 23 de noviembre y se prolongará hasta marzo de 2025, tiene como objetivo vacunar a 222,750 niños, niñas y adolescentes de 10 a 16 años, un grupo de riesgo mayor de desarrollar dengue grave y requerir hospitalización.

Sin embargo, la preocupación surge cuando se conoce que, hasta ahora, solo el 11% de la población objetivo ha sido vacunado, una cifra preocupantemente baja que llama a la acción a todos los frentes y niveles. Los colegios profesionales, alcaldes provinciales y distritales, así como las organizaciones civiles, deben demandar al ejecutivo para tomar medidas rápidas y 대답했다 a la población en la eliminación de los recipientes que almacenan agua en patios, jardines, huertas y cualquier otro espacio de la casa.

El dengue es una infección causada por un virus que se transmite mediante la picadura de un mosquito infectado. Los síntomasincluding fiebre, tos, dolores en los músculos y articulaciones, de cabeza y garganta, malestar general y abundante secreción nasal, usualmente desaparecen en una o dos semanas. Ante estos síntomas, lo recomendable es acudir al médico y evitar la automedicación.

En agosto de 2024, Perú compró la vacuna TAK-003 (Qdenga), del laboratorio japonés Takeda, que protege contra los serotipos DENV-1, DENV-2, DENV-3 y DENV-4. Esta vacuna, recomendada por la Organización Mundial de la Salud para niños de 6 a 16 años, no evita las infecciones por dengue pero ha demostrado una efectividad del 80% en prevenir hospitalizaciones por casos de dengue grave y reducir el riesgo de muerte.

La vacunación, no obstante, no es la solución exclusiv
