Dengue fever is no longer a recurring disease

Dengue fever is no longer a disease that "recurs" during the rainy season. Dengue fever now appears all year round, not limited to regions, becoming a constant threat to public health.

Dr. Nguyen Huy Luan, Head of the Vaccination Unit, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, shared: " Dengue fever is spreading both in time and geography, not only in the South, the disease is spreading in the Central Highlands and the North with hot spots being Hai Phong and Hanoi. Abnormal climate changes, unseasonal rains and prolonged abnormally high temperatures have expanded breeding conditions for disease-transmitting mosquitoes. In addition, rapid urbanization, the storage of domestic water and crowded residential areas also create an ideal environment for Aedes mosquitoes to develop. In particular, strong trade development between regions makes it easy for mosquitoes to "follow" people moving across the country, increasing the risk of outbreaks even in places where cases were rarely recorded before."

Not only is there a change in epidemiology, dengue fever also poses many potential health risks if not diagnosed and treated promptly. "We have recorded patients being hospitalized very early in the year, no longer following the old cycle of the middle and end of the rainy season as before. The number of complications has increased due to late hospitalization, many patients are hospitalized in serious condition due to being subjective with the initial symptoms. Dengue fever does not have typical symptoms, is easily confused with flu, viral fever and can cause dangerous complications such as dengue shock, plasma leakage, multiple organ failure if not closely monitored," said specialist doctor 1 Nguyen Thanh Luan, Deputy Head of the Department of Infectious Resuscitation, Children's Hospital 2, Ho Chi Minh City.

Unlike other infectious diseases, dengue fever can be reinfected up to 4 times in a lifetime due to the existence of 4 different types of viruses (DENV-1, DENV-2, DENV-3 and DENV-4). The first infection does not mean immunity, and the risk of severe progression when reinfected is even very high. In particular, all subjects, from children, adults, to pregnant women, are at risk of serious complications.

Proactive prevention of dengue fever

Dr. Nguyen Huy Luan affirmed: "To effectively control dengue fever, a comprehensive prevention strategy is needed, combining many solutions. In particular, traditional methods such as killing mosquitoes, killing larvae/wrigglers, eliminating mosquito breeding sites and avoiding mosquito bites still need to be maintained regularly and synchronously. However, these methods alone are not enough. Vaccination is a new solution integrated into existing prevention and control strategies, not only helping individuals prevent disease but also contributing to creating community immunity - a key factor in sustainable disease control".

Epidemiology changes, mosquito-transmitting habits change, so the way we prevent disease also needs to change. Taking proactive measures today, raising vigilance, from awareness of killing mosquitoes every day, monitoring early signs of disease, to accessing vaccination solutions is the most practical and urgent way for each person to protect themselves, their families and the community.

Vodcast "Dengue fever is no longer seasonal - Take the initiative to prevent it today" is produced by Ho Chi Minh City University of Medicine and Pharmacy Hospital. Led by Master Do Thi Nam Phuong, Head of the Communication Center, and specialized doctors: Doctor - Doctor Nguyen Huy Luan, Head of the Vaccination Unit of Ho Chi Minh City University of Medicine and Pharmacy Hospital; Specialist Doctor 1 Vo Thanh Luan, Deputy Head of the Department of Infectious Resuscitation, Children's Hospital 2. The program is broadcast on Youtube and Facebook of Ho Chi Minh City University of Medicine and Pharmacy Hospital.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Bee attack claims life of newspaper distributor

Bee attack claims life of newspaper distributor Newspaper distributor Pushparaja Shetty (45), who sustained severe injuries in a bee attack, succumbed to his injuries on Thursday at a hospital in Mangaluru. Pushparaja was attacked by a swarm of bees on Wednesday morning while walking at Kenjaru Taangadi under Bajpe town panchayat limits. He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

Why the Caraways are proud to “bee” farmers

Why the Caraways are proud to “bee” farmers Bees play a vital role in our ecosystem by spreading nutrients to crops, produce, and other plants. Ron and Diane Caraway are reminded of that each day on the homestead, Boggy Branch Farms, that’s been in their family for three generations. While Ron cared for the land as a teenager, he followed in his father’s footsteps and joined the U.S. Air Force after graduating high school. He managed airplanes for 45 years as an air traffic controller. Now, Ron manages flying insects as a beekeeper—or, as he puts it, a ‘bee partner.’ “They allow me to work alongside with them and to help them in some cases, with the case of parasites or diseases and I’m able to enjoy that fruit that they provide,” explained Ron. Along with raising their handful of hives, the Caraways grow hay and produce. Above all, they want to raise awareness for the bees’ essential role in making things grow. “One of the things that I think that we overlook is—in the Wiregrass ...
