Dengue fever: with a record 12.4m cases in 2024 so far, what is driving the world’s largest outbreak? Please check out this excellent article on The Guardian by Kat Lay, Tiago Rogero, and Kenneth Joseph Mohammed. https://lnkd.in/e9NwGVft Key points: 🔸 In 2024, #denguefever has surged to an unprecedented level, with over 12.4 million cases reported globally, making it the largest #outbreak on record. 🔸 Several factors are driving this massive increase. #Climatechange plays a major role, with rising temperatures, heavier rains, and increased humidity creating ideal breeding conditions for Aedes mosquitoes, the primary vectors of the #dengue #virus. 🔸 Events like El Niño exacerbate the situation by extending mosquito activity seasons and increasing rainfall in regions where dengue is endemic. 🔸 Urbanization and population growth are also significant contributors. Rapid, unplanned urban development in many regions leads to poor water management and waste disposal, creating breeding sites for mosquitoes. 🔸 Human migration spreads the virus to new areas, some of which are unprepared to handle dengue outbreaks, leading to increased transmission. 🔸 The circulation of multiple dengue serotypes further complicates the situation. In regions like Latin America and Asia, the simultaneous presence of different serotypes raises the risk of severe outbreaks and complications like dengue hemorrhagic fever, especially when individuals are exposed to more than one serotype over time. https://lnkd.in/e9NwGVft 🔸 Countries like #Brazil and #Peru have seen a dramatic rise in cases, while new regions, including parts of the U.S. and Iran, are witnessing locally transmitted cases for the first time. In response, health authorities emphasize the need for mosquito control, public education, and early detection to mitigate the spread and severity of the disease. https://lnkd.in/e9NwGVft #publichealth #globalhealth #scicomm #globaldevelopment

Thanks to Paige Hornor and Tom Mahoney for organizing this event at Harvard Studio on "Combatting the Global Threat of Dengue Fever". It was exciting to discuss the reasons behind the dengue global increases and new interventions with my fellow panelists Marcia Castro, Dan Neafsey and Guillaume Leroy. Great job from our moderator Helen Branswell raising critical questions. https://lnkd.in/ebeZvHAt

https://lnkd.in/etuehYdn Our short course on Introduction to Dengue was subscribed by 14000 learners in the past 11 months! If you want to learn some basics about Dengue, please check it out.

According to latest European Centre for Disease Prevention and Control (ECDC) figures (https://lnkd.in/exhjw9cj), there is a worsening spread of mosquito-borne disease outbreaks in EU/EEA.

World Health Organization launches global strategic plan to fight rising #dengue and other Aedes-borne arboviral diseases Today, WHO launched the Global Strategic Preparedness, Readiness and Response Plan. The Plan aims at reducing the burden of #disease, suffering and #deaths from #dengue and other #Aedes-borne #arboviral diseases such as #Zika and #chikungunya, by fostering a global coordinated response The Plan outlines priority actions to control #transmission and offers recommendations to affected countries across various sectors, including disease #surveillance, #laboratory activities, #vector control, #community engagement, #clinical management, and #research and #development, through a whole-of-society and regional approach   An estimated 4 billion people are at risk of infection from #arboviruses around the world, and this number is estimated to increase to 5 billion by 2050. Dengue cases have surged across all six WHO regions, and the number of cases has approximately doubled each year since 2021, with over 12.3 million cases as of the end of August this year – almost double the 6.5 million cases reported in all of 2023 Dengue is endemic in tropical and subtropical climates, particularly in South-East Asia, the Western Pacific and the Americas. The situation is equally concerning in Africa, where countries are battling multiple diseases amid conflict and natural disasters, placing additional strain on already fragile health systems. In December 2023, WHO graded the current global dengue upsurge as grade 3, the highest level of emergency for WHO, to support countries to strengthen their surveillance capacities and implement response activities “The rapid spread of dengue and other arboviral diseases in recent years is an alarming trend that demands a coordinated response across sectors and across borders,” said Tedros Adhanom Ghebreyesus, WHO DG. “From maintaining clean environments to supporting vector control and seeking and providing timely medical care, everyone has a role to play in the fight against dengue. This plan is a roadmap to turn the tide against this disease and other Aedes-borne arboviral diseases, protect vulnerable populations and pave the way for a healthier future.” Factors such as unplanned #urbanization and poor #water, #sanitation and hygiene practices, #climatechange and international travel, are facilitating the rapid geographical spread of dengue. The disease is now endemic in more than 130 countries. Similar trends are also observed for other arboviral diseases, such as Zika, chikungunya and more recently the #Oropouche #virus disease, especially in the Americas. This global escalation underscores the urgent need for a robust strategy to mitigate risks and safeguard #populations https://lnkd.in/eAZ7in8Y

To strengthen global surveillance, and monitor temporal trends and disease incidence, World Health Organization has established a global dengue surveillance system with monthly reporting across all WHO regions, which is now available as a dashboard (https://lnkd.in/eZDN-DEz). This has so far captured 103 countries including 28 zero reporting countries (dashboard accessed in June 2024) Visit dengueacademy.com and learn more about dengue (for an international audience of healthcare professionals outside of the US and UK) #dengue #denguefever #dengueacademy #surveillance #dashboard

Given current and future trends in human mobility, climate, and zoonotic spillover, understanding the interplay between connectivity and environmental suitability will be increasingly necessary to contain emerging and re-emerging pathogens. Harish et al. (2024; https://lnkd.in/es9Sm2cR) developed a dynamic modelling approach for infectious diseases and found that early dengue invasion is more heavily influenced by environmental factors, resulting in patchy non-contiguous spread, while short and long-distance connectivity becomes more important in later stages.

INDONESIA DENGUE REPORT  (data collected till 20 September 2024) •Total Cases : 763.971 •Confirmed Cases : 195.305 •Reported from 481 of 514 districts in 36 of 38 Provinces The trend seems to be decreasing, but currently in many places in Indonesia the rainy season has started, so there will be a lot of water reservoirs which will become a place for mosquitoes to lay eggs and grow into adults. What we have to do? 1.Continues to eradicate mosquito nests regularly at least once a week in homes, office and public places. 2.Strengthen referral networks from the community to hospitals, and the necessary logistics 3.Early detection, mandatory notification, quick response conducting epidemiological investigations 4.Strengthening community participation through IEC and electronic media.
