China reports 10,000 cases of chikungunya virus
This surge began in early 2025, with major outbreaks reported in the Indian Ocean islands of La Réunion, Mayotte and Mauritius—popular holiday destinations. So far, globally, there have been 250,000 cases and 90 related deaths in 16 countries this year, according to the European Centre for Disease Prevention and Control. There is currently no risk of contracting the virus in the UK at present, but it can be found in parts of Southern Europe. However, while concerning, experts have fortunately said it isn't going to be the next pandemic.
Professor Will Irving, a virology expert at the University of Nottingham said: 'There have been equally large, if not larger outbreaks around the world prior to this one.' However, he added: 'With climate change, the mosquitos are spreading, and there are reports of the mosquito being present in parts of Europe (France, Italy, Spain).' The virus is spread to humans by bites from infected mosquitoes but it cannot be passed from person-to-person. Several experts have shared precautionary steps those traveling the sunny beaches of Europe can take to prevent infection.
Professor Paul Hunter, a professor in medicine at the University of East Anglia, advised travelers to wear loose-fitting clothing that covers your arms and legs. Ideally, he added: 'They will be light colored, so you can see if mosquitos have landed on you.' In particular, he warned that it is a bad idea for women in late stages of pregnancy to travel to these destinations. 'If you get infected with it later on in the pregnancy, it can pose a risk to the baby,' he said.
A 2021 study found infection just prior to delivery increases risk of transmission to the baby. Professor Irving said those most vulnerable to the virus are people with immunosuppression, the very young, elderly, and those with underlying comorbidities. In the UK, so far this year, there have been 26 confirmed cases of the virus, from people traveling to Sri Lanka, India, Maldives, Oman and United Arab Emirates. However, the government said the figure includes individuals who travelled to more than one country—so the number may be higher than actual cases.
Previously the virus was more commonly found in Asia, Africa and South America, but more recently cases have emerged in Europe and the US. The chikungunya virus has also spread to Madagascar, Somalia, Kenya and India and is making its way to Europe. Case counts have also been increasing in Samoa, Tonga, French Polynesia, Fiji and Kiribati. Meanwhile there have been 46 cases of chikungunya infections in the US this year, all contracted by travelers returning from high-risk areas, but no deaths.
The majority of people infected with Chikungunya develop a sudden fever and severe pain in multiple joints. Other symptoms may include headache, muscle pain, joint swelling, or rash. The virus is spread to humans by bites from infected mosquitoes, but cannot be passed from person-to-person. Symptoms typically resolve within seven to 10 days, and most patients make a full recovery. However, in some cases the joint pain and arthritis may persist for several months or even years.
Occasional cases of eye, neurological and heart complications have been reported, as well as gastrointestinal complaints. A small number of people may develop a severe version of the disease, which can lead to multiple organ failure and death. Severe symptoms and deaths are rare and usually occur in young babies or elderly people with coexisting health problems. There is no specific antiviral treatment for chikungunya but medications (such as paracetamol) for fever and pain can be used to alleviate these symptoms.
There are currently two vaccinations which protect against the virus; IXCHIQ for those aged between 18 and 64 and Vimkunya for those 12 years and older. In the UK, the vaccine is given to those who travel abroad to certain regions where the chikungunya virus is present. However, unfortunately, some of the most vulnerable to the virus are those who cannot get the virus—those who are immunosuppressed.

UKHSA warning as France, Italy and others report Chikungunya virus cases
Holiday hotspots like France, Italy and Cuba have all reported locally acquired cases of the mosquito-borne illness The UK Health Security Agency is warning travellers bound for certain international destinations to remain alert for the Chikungunya virus, which is sparking growing concern. Sharing guidance on X, the agency stated: "There is currently no onward transmission in the UK, but for those travelling to at risk countries our blog post offers the best advice on prevention and protection." Initial symptoms of Chikungunya encompass headaches, light sensitivity, skin rashes, high fever and excruciating joint pain. This may impact smaller joints or previously injured areas. While most people make a complete recovery within several weeks, the joint discomfort can linger for years in certain instances. Research shows that up to 12% of patients continue experiencing pain three years following infection. Mosquitoes transmit the virus, which derives its name from the Kimakonde language of Southern Tanzania, translating to 'that which bends up' due to the agonising joint pain it triggers. For decades, it remained confined to regions of Africa and Asia, but has now spread worldwide with outbreaks emerging across numerous popular holiday destinations this summer. Countries reporting Chikungunya cases within the past month, according to Travel Health Pro: France China Cuba Hong Kong Italy Mauritius Bangladesh Mayotte Health agencies express concern over China's nearly 5,000 confirmed cases of a virus spread across 12 cities in Guangdong Province. The UKHSA has highlighted that the global spread of the virus is likely due to changing climates that create more suitable environments for disease-carrying mosquitoes. The Chikungunya mosquito, unlike those that carry malaria and are mostly nocturnal, is active during the day, prompting a warning for travellers to high-risk countries to be vigilant during daylight hours. To avoid contracting the illness, UKHSA recommends "rigorous" mosquito bite prevention tactics. These measures include wearing light-coloured, loose clothing that covers both arms and legs, and applying repellent to any exposed skin. The agency also advises: "Travellers should also be aware that these mosquitoes breed in standing water around human habitation." To minimise exposure risk, avoiding areas with natural and artificial water containers is suggested. Aedes mosquitoes, which transmit the virus, prefer urban settings and are known to bite indoors, making it crucial to take precautions even inside hotel rooms. For UK travellers seeking additional protection, two new vaccines have been approved, although they come with certain limitations. More information about these vaccines can be found here.

Woman, 41, had parasitic WORMS crawling under her eyelid after telling docs ‘something was stuck in her eye' for a month
IT'S pretty common to feel like something's stuck in your eye - even when there isn't anything visible there. Dry eyes, scratches on the eye, or foreign objects like dust or an eyelash are popular culprits. 4 4 But when one woman went to hospital on multiple occasions when the feeling wouldn't go away, it turned out to be parasites. In a case report published in BMC Ophthalmology, the 41-year-old decided to seek medical help after feeling like there was something stuck in her right eye. At first, doctors examined her eye, noted the outer surface, the cornea, appeared damage, but didn't find any foreign bodies. They prescribed the patient, who was living in Beijing, eye drops, one type to treat the eye irritation and another with antibiotics in it to help prevent infection. However, the eye drops didn't east her symptoms, and the next month she returned to the hospital reporting the same feeling something was stuck in her eye. Persistent eye redness and itchiness had also developed. Doctors reexamined he eye and this time noticed the tissue beneath her upper eyelid looked inflamed. There were also "significant pimple-like bumps", authors of the case report wrote. Using a device called an eyelid retractor, they pulled back her eyelid to more closely examine the tissue beneath. Upon more detailed inspection, the doctors found four small, white worms crawling around. I thought I had sand in my eye - now I'm blind after parasite burrowed into my cornea The medical team proceeded to apply a topical anaesthetic to numb the area, and then removed the worms with forceps. The worms were then sent to a lab for examination. A microscopic and genetic analysis of the worms revealed that they were a species called thelazia callipaeda, also known as the oriental eye worm, which can cause a parasitic infection called thelaziasis. After ensuring the woman had no more worms, doctors rinsed out her eye with a solution and prescribed her an ointment containing an antibiotic to reduce the risk of a subsequent bacterial infection. "One week later, the patient's symptoms were significantly relieved, and no recurrence was reported over the following two months," the doctors wrote. Thelaziasis is rare in humans, and tends to be more common in animals. 4 4 It's primarily transmitted by drosophilid flies (fruit flies) that act as intermediate hosts. These flies feed on the lacrimal secretions (tears) of infected animals, ingesting larvae, which then develop into an infective third-stage larva within the fly. When the fly then feeds on the eyes of another animal (or human), it deposits the infective larvae, transmitting the infection. Historically, most cases of thelaziasis in humans have been reported in Asia, with China reporting the largest number overall. Between the country's first known human cases in 1917 and 2018, more than 650 cases have been reported. "Thelaziasis cases have been reported mainly in agricultural areas and areas with high potential for contact with domestic animals," the report authors noted. But in the case, the source of the woman's infection wasn't certain. She was an office worker based in an urban setting, and didn't recall a recent exposure to flying insects. She did, however, report having a pet cat who'd recently had an eye infection. But a pathological examination of the cat wasn't performed as the patient refused. The report authors concluded, even in urban areas, doctors should be aware of the symptoms of thelaziasis and consider it as a potential diagnosis. Symptoms can range from mild to severe, including the feeling of something in your eye, itching, eye pain, bleeding or inflammation of the tissue covering the eye and eyelids, ulcers in the cornea, and vision changes. Doctors should ask about whether patients have pets or have had recent contact with flying insects, they added.

Century-old pair of lungs stored in jar reveals how 1918 Spanish flu pandemic began
A pair of lungs preserved over a century ago from a deceased Spanish flu patient has helped unravel the genetic adaptations undergone by the virus to spread across Europe during the start of the 1918 pandemic. The Spanish flu pandemic of 1918-1920 was one of the most devastating pandemics in history, claiming some 20 to 100 million lives worldwide. However, little is known about how the flu virus mutated and adapted throughout the pandemic. Understanding how viruses evolved during past pandemics remains crucial for developing targeted countermeasures for the future, researchers say. Scientists have now reconstructed the first Swiss genome of the influenza virus behind the 1918 pandemic, helping unravel how it spread across Europe during its initial waves of infections. Researchers used an over 100-year-old virus sample taken from a formalin-fixed lung specimen in the Medical Collection of Switzerland's University of Zurich. The virus sample was taken from an 18-year-old patient from Zurich who died during the first wave of the pandemic in Switzerland and underwent an autopsy in July 1918. 'This is the first time we've had access to an influenza genome from the 1918–1920 pandemic in Switzerland. It opens up new insights into the dynamics of how the virus adapted in Europe at the start of the pandemic,' said Verena Schünemann, a co-author of the study from the University of Zurich. Researchers compared the Swiss genome with versions previously published from Germany and North America to find that the Swiss strain already carried three key adaptations to infect and spread among humans that would persist in the virus until the end of the pandemic. Two of these mutations seem to have made the virus more resistant to the human immune system, an important barrier against the transmission of such flu viruses originating from animals. Another mutation of a protein in the virus's membrane improved its ability to bind to entry point receptors in human cells, making it more resilient and infectious. In the study, scientists used a new method with improved ability to recover ancient RNA fragments from specimens. 'Medical collections are an invaluable archive for reconstructing ancient RNA virus genomes. However, the potential of these specimens remains underused,' said Frank Rühli, another author of the study. Researchers hope future studies using the method could lead to a better understanding of how viruses adapt to humans during a pandemic, enabling us to better anticipate and adapt to future pandemics.
