These striking images narrate a grave tale of climate change and the spread of dengue fever, a disease recognized as the world’s fastest-growing mosquito-borne illness.

Photographer Yuri Segalerba presents a photo essay focusing on the alarming increase in temperature and the emergence of dengue fever in the Himalayan region of Nepal. Nestled at 2,438 meters above sea level, Chandannath is one of the highest towns where Aedes aegypti and Aedes albopictus mosquitoes and their larvae have been found. These mosquitoes, known carriers of dengue fever and other illnesses, were previously noted only up to an altitude of 2,100 meters.

Segalerba, who studies how traditional knowledge systems react to external pressures, was exploring dengue’s spread to Peru’s high Andes when he stumbled upon alarming developments in Nepal: “This was an ideal setting for my inquiry—where an ancient medical tradition confronts a disease it has never encountered,” he reflects.

Due to climate change and increased travel, dengue fever has proliferated across vast regions of Nepal. Reports indicate that in 2025, an estimated six fatalities from dengue fever occurred, with around 9,000 infections reported, spreading the virus to 76 out of 77 districts in the country, according to Kathmandu News.

This close-up reveals a female Aedes aegypti. The Nepal Health Research Council (NHRC), in collaboration with the Institute of Tropical Medicine in Antwerp, Belgium, is studying adult mosquitoes and larvae for color and shape alterations. These changes indicate potential resistance to insecticides and adaptations to different altitudes.

The research is supported by Mr. Ishan Gautam, Associate Professor and Director of the Natural History Museum at Tribhuvan University, Kathmandu. The larvae were sent to Geetamata Junior High School in Kathmandu, where an awareness campaign is being conducted to educate locals about Aedes mosquito habits, emphasizing the importance of eliminating breeding sites such as stagnant water.

Experts warn that these figures likely underrepresent the disease’s prevalence, as about 90% of cases show no symptoms, leaving many infections and deaths unreported.

Review of “A Boy with Dengue” by Michel Nieva from Book Club Members: Candid Thoughts

Michelle Nieva and his novel, Dengue Boy

I’ve read all sorts of things from classic slices of Dystopian Fiction by Octavia E. Butler at the New Scientist Book Club. The Memories of SowingAdrian Tchaikovsky’s Space Exploration Alien clay. Michel Nieva Dengue fever boy (And if you haven’t read it yet, this is not an article for you: spoilers first!) was something completely different.

There was part of this novel I loved, especially the wild originality of Nieva, who dreams of his future world. This is where Antarctic ice thawed in 2197, and sea level rise means that Patagonia, once famous for its forests, lakes and glaciers, has transformed into a scattered path on a small, burnt hot island.

It is the place where “hundred thousands of unrecorded viruses emerge each year thanks to the complete deforestation of all forests in the Amazon and China and Africa.” And when the infinite and terrible ingenuity of humanity means that people are currently trading on the Financial Virus Index. Powered by quantum computers, this is “not only determined at 99.99% effectiveness, but it is likely that these new viruses will not only unleash a new pandemic, but will collect stocks from companies that are likely to benefit from its effectiveness and offer them to the market in packages sold like pancakes.” Great idea!

I also think Nieva’s writing (translated by Rahul Bery) will occasionally leap to elevated levels. At some point, our hero is early in school (because she can fly there, unlike she’s narrated in traffic). She needs to “wait completely still for a few minutes, minutes, minutes, minutes, minutes, no idea what her excessive cor should do.” Excessive corporateity! It would be a glorious and appropriate explanation of this miserable mosquito.

It has an unbearable emotional feeling. This was with me after finishing and stayed with the vision of Niwa’s great iceberg gallery. “I couldn’t walk through the Great Iceberg Gallery and in the early stages I couldn’t feel the sudden weight of the world. The relic box of true planetary gemstones, its total age was greater than that of all humankind.”

And I can only admire Neeva’s virtuosity in thinking of myself in the mind of a murderous mosquito. I think he can do this a lot. My sympathy enjoys what half of us wanted with our “stubbornly murderous” hero, half of which was violently postponed by her actions.

Some of you have seen a lot of positive things in the novel. “If I solved that this is not science fiction, but a realism of the magic of South Americans, I enjoy it (a huge fan of Gabriel Garcia Marquez, Italo Calvino, and Umberto Eco. It’s a completely different genre.” Facebook Groupwhere do all these comments come from? “It’s weird, surreal and all-talented, and I think it works very well in these terms.”

For Terry James, the book began hard. We need to deal with “rough language” as we needed a lot of disbelief halts to embrace the protagonist of Nieva’s mosquito (and its incredible size). However, Terry was happy he kept going. “The more I read, the more I enjoyed it. I found literary techniques to reveal the inner struggle of the wealth, privilege and the gorgeousness of the poor, as very effective,” he wrote. “This book is creative.”

I think David Jones nailed it when he said “reading isn’t comfortable,” but he “actually enjoyed it a lot.” “It’s a very dystopian satirical, very bloody view of the future. It’s the day you read and digest how I felt about it,” he writes.

But perhaps this is because I am not a steampunk enthusiast, as the novel is mentioned on its cover. The “excessive corporation” I enjoyed with mosquitoes comes in a variety of scenes of violence and sexual depravity that I found difficult to read. I’m a Stephen King fan – I don’t mind a bit of fear and gore. But I really didn’t understand what brought richness to the story here other than making me totally terrible. I hated the sheep! I really hate it! (As some may say, that was the point, but for me it was a point that I wasn’t keen on being made.)

And when our mosquitoes were on a bloody adventure, I found it later on when we were on a bloody adventure that was far more convincing than the Borges-esque “Computer Games in Computer Games” section we had reached. It was on the wrong side of Surreal for me, or I wasn’t getting it. Terry James also had problems with the “Mighty Anarchy” component of the story and was unable to grasp its meaning. “I call this kind of ideology pseudointelligence, because it sounds very clever, but doesn’t make sense in a holistic, integrated system,” he wrote.

Overall, for me, this is not the book I’m coming back to, and I think the majority of our members were also more negative about this than positive. Judith Lazelle felt that was “unfortunate.” “Free sexual fantasy and undeveloped characters, violence is explicit and rebellious. Perhaps that was the point,” she wrote. [was] It’s effective in bringing back memories of terrible places to live.”

For Eliza Rose and Andy Feest, it was their least favorite book club ever read. Like me, Eliza wasn’t a fan of body horror, but she liked some of the corrupt companies in the storyline. “I think he’s finished it well enough because he feels like he told the story, but I didn’t need all the gore,” she wrote.

Andy described the story as “plain and weird,” and Nieva came up with an interesting concept, but he felt he could have used more backstory and details. “The end was a shame (I can’t say I’m confused),” Andy writes. “Overall, I was grateful that this was a short book because I wasn’t sure if it was a bigger novel (and I hate that I haven’t finished the book I started paying for).

Perhaps Andy doesn’t have to pay for the next book: We’re reading: Larry Nivens Ring WorldAn old classic that many of you may have on your shelf. Come and tell us what you think about us Book Club Member Facebook Pagetry this excerpt and get insight into how Larry came up with the work he wrote here to come up with the epic creation mechanisms.

Potential Spread of Dengue Fever-Carrying Asian Tiger Mosquitoes to the UK Within Decades | Latest UK Updates

The Asian tiger mosquito, which carries dengue fever, could be endemic in Britain by mid-century, government health experts say.

In recent years, insects have spread to most of Europe due to the warmer climate, tending to live in urban areas and feed during the day, putting people at greater risk.

They have striped bodies and are known for their ability to spread dengue fever, Zika virus, and chikungunya fever (diseases usually associated with tropical regions).

The UK Health and Safety Agency (UKHSA) fears dengue fever could be transmitted in London by 2060, and mosquitoes themselves could be widespread across the UK by the 2040s.

UKHSA entomologist Jolyon Medlock said surveillance at borders could help slow the spread of mosquitoes, and people should cover standing water and empty containers as the insects lay their eggs to keep mosquitoes away.

Professor Dame Jenny Harries, chief executive of the UKHSA, said: “What was called a tropical disease when I was trained many years ago will actually become a national household disease.”

Officials also said other food- and water-borne infections could become more common, increasing the risk of further pandemics.

The dangers of heatwaves will worsen, flooding will become more severe, and people’s mental health may be adversely affected.

Food prices could also become more volatile, as much of the food the UK imports comes from areas prone to climate impacts such as drought.

Wildfires that produce toxic smoke are also expected to occur more frequently during hotter, drier summers.

Young children, the elderly, and people with pre-existing conditions are most vulnerable to these threats.

“In the summer of 2022, temperatures in the UK exceeded 40 degrees for the first time on record,” Dame Jenny said.

“Nearly 3,000 excess deaths were recorded during this prolonged heat wave, while many other countries have experienced extreme heat and prolonged heat waves in recent months.

“Using a high emissions scenario, health-related deaths in the UK are estimated to increase by more than 100% in the 2030s, more than 500% in the 2050s and more than 1,000% by 2070.”

Doctors fear an outbreak could occur in the UK too – and here’s why

The Earth is already 1.2 degrees warmer than pre-industrial levels, and given the amount of carbon in the atmosphere, further warming is already locked in, even if emissions start to fall overnight.

This means some adaptation will be needed, alongside emissions reductions, housing improvements, flood protection and extreme heat warnings, UKHSA said.

Mrs Jenny added: ‘Climate change is an important threat to public health around the world, not only through increased mortality from extreme temperatures and weather impacts, but also through increased spread of infectious diseases and worsened earth system vulnerabilities.”
