virus

AS the UK waves goodbye to summer, experts are urging people to take extra precautions to stay healthy.

As winter illnesses start to circulate, one virus parents are being asked to be especially wary of is RSV – as new evidence shows it can be just as risky to healthy babies as those born premature of with underlying health conditions.

RSV, which stands for respiratory syncytial virus, is a common cause of respiratory infections in young children and accounts for around 245,000 hospital admissions annually in Europe. 

In some cases, it can lead to more severe respiratory issues like bronchiolitis and pneumonia, which can lead to hospitalisation, the need for oxygen or mechanical ventilation, and even death.

Researchers have now analysed data from more than 2.3 million children born in Sweden between 2001 and 2022 to find out who is at greatest risk of suffering serious complications or dying from an RSV infection

Almost all children will get RSV at least once before they’re two years old.

Premature babies and children with chronic diseases are known to be at increased risk of developing severe illness when infected with the virus.

And children under three months of age are also particularly vulnerable – although it hasn’t been entirely clear how common severe disease is among previously healthy children. 

As part of their findings, scientists from Karolinska Institutet in Sweden found the largest group among the children who required intensive care or were hospitalised for a long period of time were under three months of age, previously healthy and born at full term.

“When shaping treatment strategies, it is important to take into account that even healthy infants can be severely affected by RSV,” said the study’s first author, Giulia Dallagiacoma, a physician and doctoral student at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet.

“The good news is that there is now preventive treatment that can be given to newborns, and a vaccine that can be given to pregnant women.”

The NHS RSV vaccine programme was launched in England on September 1, 2024 offering protection to pregnant women from 28 weeks gestation to protect their baby and to older adults aged 75 to 79.

Several factors were linked to an increased risk of needing intensive care or dying by the researchers.

Children who were born in the winter, or had siblings aged 0–3 years or a twin, had approximately a threefold increased risk, while children who were small at birth had an almost fourfold raised risk.

Children with underlying medical conditions had more than a fourfold increased risk of severe illness or death.

“We know that several underlying diseases increase the risk of severe RSV infection, and it is these children who have so far been targeted for protection with the preventive treatment that has been available,” said the study’s last author, Samuel Rhedin, resident physician at Sachs’ Children and Youth Hospital and associate professor at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet.

“However, the study highlights that a large proportion of children who require intensive care due to their RSV infection were previously healthy.

“Now that better preventive medicines are available, it is therefore positive that the definition of risk groups is being broadened to offer protection during the RSV season to previously healthy infants as well.”

In the UK, if you’re pregnant, you should be offered the RSV vaccine around the time of your 28-week antenatal appointment.

If you’re aged 75 to 79 (or turned 80 after 1 September 2024) contact your GP surgery to book your RSV vaccination.

Spotting RSV symptoms is important to help prevent serious complications.

Most people who get an RSV infection will only get cold-like symptoms, according to the NHS, including the five following signs:

• a runny or blocked nose
• a cough
• sneezing
• tiredness
• a high temperature – signs include your back or chest feeling hotter than usual, sweatiness and shivering (chills)

Babies with RSV may also be irritable and feed less than usual.

But if RSV leads to a more serious infection (such as pneumonia or bronchiolitis) it may also cause a worsening cough, shortness of breath, faster breathing, difficulty feeding in babies, wheezing, and confusion in older adults.

It’s important to note cold-like symptoms are very common in babies and children and aren’t usually a sign of anything serious.

They should get better within a few days.

There’s no specific treatment for an RSV infection as it often gets better on its own in one or two weeks.

If you or your child have mild RSV symptoms, there are some things you can do to help ease symptoms at home, including taking paracetamol or ibuprofen if you have a high temperature and are uncomfortable (giving children’s paracetamol or children’s ibuprofen to your child) and drinking lots of fluids.

But children and adults who get a more serious infection may need to be treated in hospital.

For five years, I dodged every bullet.

I don’t know how I managed to beat COVID-19 for so long, even as family, friends and colleagues got hit with the coronavirus. Although I took precautions from the beginning, with masking and vaccinations, I was also out in public a lot for work and travel.

But my luck has finally run out, and it must have been the air travel that did me in. I returned from a cross-country trip with a razor blade sore throat and a stubborn headache, followed by aches and pains.

The first test was positive.

I figured it had to be wrong, given my super-immunity track record.

The second test was even more positive.

So I’ve been quarantined in a corner of the house, reaching alternately for Tylenol and the thermometer. Everything is a little fuzzy, making it hard to distinguish between the real and the imagined.

For instance, how can it be true that just as I get COVID for the first time, the news is suddenly dominated by COVID-related stories?

It has to be a fever-induced hallucination. There’s no other way to explain why, as COVID surges yet again with another bugger of a strain, the best tool against the virus — vaccine — is under full assault by the leaders of the nation.

They are making it harder, rather than easier, to get medicine recommended by the overwhelming majority of the legitimate, non-crackpot wing of the medical community.

Under the new vaccine policies, prices are up. Permission from doctors is needed. Depending on your age or your home state, you could be out of luck.

Meanwhile, President Trump fired Susan Monarez, the head of the U.S. Centers for Disease Control and Prevention, essentially for putting her own professional integrity and commitment to public service above crackpot directives from a cabal of vaccine skeptics.

And following Health and Human Services Secretary Robert F. Kennedy Jr.’s cancellation of $500 million in mRNA vaccine research, Trump is demanding that pharmaceutical companies show proof that vaccines work.

My eyes are red and burning, but can COVID be entirely to blame?

I got a booster before my travels, even though I knew it might not stand up to the new strain of COVID. It’s possible I have a milder case than I might have had without the vaccine. But on that question and many others, as new waves keep coming our way, wouldn’t the smart move be more research rather than less?

Trump downplayed the virus when it first surfaced in 2019 and 2020. Then he blamed it on China. He resisted masking, and lemmings by the thousands got sick and died. Then he got COVID himself. At one point, he recommended that people get the vaccine.

Now he’s putting on the brakes?

My headache is coming back, my eyes are still burning, and unless my Tylenol is laced with LSD, I think I just saw a clip in which Kennedy and Defense Secretary Pete Hegseth attempted 50 pull-ups and 100 push-ups in 10 minutes.

I appreciate the health and fitness plug, and because Kennedy and I are the same age — 71 — it’s impressive to see him in the gym.

But there’s something that has to be said about the Kennedy-Hegseth workout tape:

They’re cheating.

Take a look for yourself, and don’t be fooled by the tight T-shirts worn by these two homecoming kings.

Those were not full chin-ups or push-ups.

Not even close.

Cutting corners is the wrong message to send to the nation’s children, or to any age group. And how is anyone going to make it to the gym if they come down with COVID because they couldn’t get vaccinated?

Honestly, the whole thing has to be a fever dream I’m having, because in the middle of the workout, Kennedy said, and I quote, “It was President Trump who inspired us to do this.”

He is many things, President Trump. Fitness role model is not one of them, no matter how many times he blasts out of sand traps on company time.

Getting back to cutting corners, Kennedy said in slashing mRNA research that “we have studied the science,” with a news release link to a 181-page document purportedly supporting his claim that the vaccines “fail to protect effectively.”

That document was roundly eviscerated by hordes of scientists who were aghast at the distortions and misinterpretations by Kennedy.

“It’s either staggering incompetence or willful misrepresentation,” said Jake Scott, an infectious-disease physician and Stanford University professor, writing for the media company STAT. “Kennedy is using evidence that refutes his own position to justify dismantling tools we’ll desperately need when the next pandemic arrives.”

I lost my sense of smell a few days ago, but even I can tell you that stinks.

The mosquito-borne virus has crossed the Taiwan Strait from southern China, where confirmed cases of chikungunya top 8,000.

Taiwan has reported its first confirmed case of chikungunya fever, imported from China, where a historic outbreak of the mosquito-borne virus is under way.

Chikungunya has swept through southern China in recent weeks, primarily in the manufacturing hub of Foshan on the Pearl River Delta, with cases rising to more than 8,000. The outbreak is the largest on record, according to Roger Hewson, virus surveillance lead at the United Kingdom’s Wellcome Sanger Institute.

Taiwan’s Centers for Disease Control (CDC) said on Friday that the chikungunya virus was detected in a Taiwanese woman who had travelled to Foshan and returned to Taiwan on July 30.

It was the first case of its kind detected so far in 2025, though more than a dozen cases have been previously detected and originated in Indonesia, the Philippines and Sri Lanka.

The CDC has raised its travel advisory for China’s Guangdong province, the epicentre of the outbreak, to level 2 out of 3, urging travellers to use “enhanced precautions”.

The virus can lead to high fever, rash, headache, nausea and fatigue lasting up to seven days, and muscle and joint pain that can last for several weeks.

“The outbreak in Foshan and surrounding areas of Guangdong province has unfolded rapidly and at a scale unprecedented for China,” Hewson said in a statement.

The surge is due to limited immunity in China and “environmental suitability” for the virus-carrying Aedes aegypti and Aedes albopictus mosquitoes, which breed in stagnant water, he said.

Chinese health authorities have responded with containment strategies ranging from household-level inspections and enforced bed nets, to drone-based fogging and even quarantines, reminiscent of the COVID-19 pandemic, Hewson said.

The Associated Press news agency reported that residents of Foshan can be fined as much as up to 10,000 RMB ($1,400) for keeping water in outdoor containers – a popular breeding ground for mosquitoes.

The outbreak follows more than a month of typhoons and heavier-than-usual monsoon rains in China.

Last week, Hong Kong – located some 180km (110 miles) from Foshan – was hit by its worst August rainstorm since records began in 1884.

Chinese state media said despite the historic number of chikungunya cases, the outbreak appears to have finally peaked.

Foshan reported 2,892 local infections from July 27 to August 2, but no severe or fatal cases, according to China’s state-run Xinhua news agency.

“The recent surge has been initially contained, with a downward trend in newly reported cases across the province,” Kang Min, director of the infectious disease control institute at the Guangdong Provincial Center for Disease Control and Prevention, told Xinhua.

United States health officials are urging travellers to remain vigilant as a mosquito-borne virus continues to circulate across parts of Asia, Africa, Europe, Latin America and the Indian Ocean.

Since the beginning of 2025, there have been approximately 240,000 chikungunya virus infections and 90 deaths in 16 countries, according to the European Centre for Disease Prevention and Control (ECDC).

In China, an outbreak has infected roughly 7,000 people since late June, with most cases concentrated in the city of Foshan, in Guangdong province, just north of Hong Kong. This marks the country’s largest chikungunya outbreak since the virus was first identified there in 2008.

Here is what we know about the disease and how it is spreading.

What is the chikungunya virus?

Chikungunya is a viral disease that is spread through the bite of infected Aedes aegypti mosquitoes. These mosquitoes also carry and spread dengue, yellow fever and the Zika virus.

The name, chikungunya, derives from a word in the Kimakonde language, spoken in Tanzania and Mozambique, meaning “to become contorted”.

In most cases, patients will feel better within a week. In many cases, however, the joint pain can last for months or even years.

There is no cure for the chikungunya virus, but deaths are rare. If an infected mosquito bites a healthy human, it injects the virus into the bloodstream.

People most at risk of serious illness from chikungunya include newborns, older adults and those with existing health problems such as heart disease or diabetes.

There is no cure for the chikungunya virus, but the death rate is low, except in high-risk populations.

If an infected mosquito bites a healthy human, it injects the virus into the bloodstream. If a non-infected mosquito bites a person who is already infected, it sucks the virus from that person’s blood and becomes a carrier capable of transmitting the virus to others through bites.

How bad is the current spread of the virus?

According to the World Health Organization (WHO), the current surge in cases began in early 2025, with major outbreaks in Indian Ocean Islands, including La Reunion, Mayotte and Mauritius.

In La Reunion, more than 47,500 cases of chikungunya and 12 associated deaths were reported up to May 2025, with sustained high transmission across the island, according to the WHO. The ECDC also reports that as of July 18, there were more than 54,000 cases reported from La Reunion.

This is now the most serious chikungunya outbreak in La Reunion since the 2005–2006 epidemic, which saw an estimated 244,000 to more than 300,000 cases, and prompted large-scale public health efforts to control mosquito breeding and limit transmission.

The virus has also spread to other countries, including Madagascar, Somalia and Kenya, and has shown signs of epidemic-level transmission in parts of Southeast Asia, as well as India, where financial capital Mumbai has seen a surge in cases since July.

The WHO has also raised concerns about the rising number of imported chikungunya cases in Europe. Since May 1, about 800 imported cases have been reported in mainland France.

According to the ECDC, the Americas as a region have reported the highest number of chikungunya cases globally. As of mid-July 2025, the countries with the most cases in the region include Brazil (185,553), Bolivia (4,721), Argentina (2,836) and Peru (55).

In China, infections have been reported in at least 12 cities across southern Guangdong province, in addition to Foshan.

Chinese authorities said that an “imported case triggered local transmission” in July, but did not specify where the infection originated. According to experts, rising global temperatures have led to warmer and wetter weather, allowing mosquitoes to thrive.

Separately, on Saturday, Hong Kong confirmed its first case of chikungunya: a 12-year-old boy who developed a fever, rash and joint pain since July 31, after visiting Foshan. This was the territory’s first case of the virus in six years.

How are China and other countries fighting the spread?

According to a Bloomberg news report, China has promised to take swift and decisive action to contain the spread of the chikungunya virus.

Drones are being used to find places where mosquitoes are breeding. At the same time, scientists are releasing large “elephant mosquitoes” – about 2cm (0.8 inches) long – whose larvae eat the smaller mosquitoes that spread the virus. Health experts hope these mosquito helpers will play an important role in stopping the outbreak.

According to a report by the BBC, residents of affected areas in China have been ordered to eliminate standing water in and around their homes – including in flowerpots, coffee machines and empty bottles. Noncompliance may result in fines of up to 10,000 yuan (approximately $1,400), and in more serious cases, people could face criminal charges for “obstructing the prevention of infectious diseases”.

Citing local sources, The New York Times said that in some instances, infected residents in Foshan are being moved to “quarantine wards”, where they are kept behind mosquito nets and screens. Some patients also say they were given no choice but to seek treatment at their own expense.

In other places, such as La Reunion and Mayotte, authorities have also launched enhanced surveillance, mosquito control initiatives and targeted vaccination efforts.

The Basque Country in Spain activated preventive protocols after a case was detected in Hendaye, just across the border in France. The protocols include increased surveillance in border towns and encouraging people to make reports through apps such as Mosquito Alert.

How can chikungunya be prevented and treated?

Health authorities advise protecting oneself against mosquito bites as the most effective strategy against the spread of chikungunya.

This may involve wearing long sleeves and trousers, applying mosquito repellents, removing bodies of standing water where mosquitoes can breed, and staying in closed, air-conditioned spaces indoors or behind mosquito netting when outdoors.

While there are no specific medicines to treat the virus, rest, fluids and pain relievers may help alleviate symptoms, according to the US Centers for Disease Control and Prevention (CDC).

However, some pain relievers may be unsafe during a suspected infection. The CDC recommends avoiding non-steroidal anti-inflammatory drugs (NSAIDs) until dengue is ruled out, as they can raise the risk of bleeding.
