European beachgoers face risks from sea bacteria as summer heats up

Euronews5 days ago
As holiday-goers flock to Europe's beaches this summer, health authorities are warning about the growing health risks from bacteria that thrive in warm, brackish water.
The European Centre for Disease Prevention and Control (ECDC) issued an alert over Vibrio bacteria, which are often found in the Baltic Sea but are now appearing across Europe as sea temperatures rise.
'The bacteria live naturally in brackish coastal waters, where saltwater and freshwater mix, especially when temperatures are high and salinity is lower,' the ECDC said.
'These conditions are becoming increasingly common in parts of Europe due to climate change,' the agency added, noting that the bacteria has been found in the North Sea and enclosed bathing sites.
Vibrio bacterial infections, called vibriosis, can cause serious health issues. People can be infected by eating raw or undercooked shellfish, particularly oysters, or by swimming in bacteria-heavy waters while they have a cut or another open wound.
People with weakened immune systems or chronic liver conditions are at higher risk from complications such as sepsis, bloodstream infections, flesh-eating disease or even limb amputation.
These infections are still 'relatively rare' in Europe, the ECDC said. But several northern countries around the Baltic Sea have reported an increase in cases in recent years, particularly in summers with longer heatwaves.
In 2018, for example, 445 cases were reported during one of Europe's hottest summers on record. That's more than triple the median of 126 cases recorded per year between 2014 and 2017.
But that is likely an undercount because infections are 'probably under-reported,' the agency said.
The ECDC recommends that people avoid eating raw shellfish and ensure their seafood is cooked thoroughly. It also said people with cuts or recent piercings should avoid swimming in brackish or salty water or cover their cuts with waterproof bandages.
The agency advised people to 'be aware of the risks and to consult a doctor if symptoms appear after contact with the type of water where Vibrio bacteria thrive'.

Hot European summers raise health risks from mosquito-borne diseases

Europe is in for a long, hot summer – and with it, a swarm of mosquitoes. The insects are more than just pesky. Some mosquito species carry illnesses such as Zika, West Nile virus, dengue, and chikungunya – and outbreaks of these diseases, typically found in tropical and subtropical climates, are becoming more common in Europe as a result of increased travel and warmer weather driven by climate change. Last year, there were 1,436 cases of West Nile virus and 304 dengue infections acquired in Europe, up from 201 the previous two years combined, according to the European Centre for Disease Prevention and Control (ECDC). Italy made up 238 of those dengue cases, the largest outbreak the bloc has ever seen. This may be another record-breaking year. France already has seven active outbreaks of chikungunya this summer, which the ECDC said indicates the mosquito season started earlier than usual. 'It's an exponential curve,' Jan Semenza, an environmental epidemiologist at Umeå University in Sweden, told Euronews Health. Dengue can spread easily because most infected people have no or mild symptoms, but it can cause severe illness and death. The most common symptoms are fever, headache, body aches, nausea, and rash. Chikungunya is rarely fatal, but it can cause similar symptoms to dengue as well as debilitating joint pain that can last months or even years. Semenza and other scientists believe these diseases could soon become endemic in Europe. One recent study found that if a new mosquito species arrived in a European country in the 1990s, it would take about 25 years for a major outbreak to occur. Now, it's under five years. 'That time span has collapsed dramatically,' Semenza said. Outbreaks in Europe are still small compared to the rest of the globe. So far in 2025, there have been more than three million dengue cases and 220,000 chikungunya cases worldwide. More than 1,400 people have died from dengue and there have been 80 chikungunya deaths worldwide. But other vector-borne diseases could soon emerge as public health threats, as well. The mosquito species that spreads yellow fever, once eliminated in Europe, has reappeared in Cyprus. 'We are very concerned that Europe could potentially be invaded by this aggressive mosquito,' Semenza said. What can be done to combat mosquito-borne diseases? Semenza said that while it's impossible to eliminate mosquitoes altogether, governments can do more to prevent them from spreading disease. They could, for example, boost surveillance in hotter southern European countries during the summer, particularly around airports and other transit hubs where people might unknowingly bring viruses in. 'We want to make sure that if a passenger arrives from a dengue-active area, that if that person has the virus in [their] blood, we would like to isolate that individual as quickly as possible to make sure that he or she doesn't get bitten by a mosquito, because then you have these larger outbreaks,' Semenza said. Spain is taking some steps to minimise the risks. People can submit photos of mosquitoes to an app that uses artificial intelligence (AI) to identify the species and issue an alert if it hasn't been detected in that area before. Regional health authorities can then take steps to prevent infections. This 'citizen science' programme has helped officials identify invasive Asian tiger mosquitoes, which can carry dengue and chikungunya viruses, in 156 municipalities since 2023, according to the Spanish health ministry. Meanwhile, the ECDC said people can take steps to minimise their own risks from mosquitoes , including using insect repellent and wearing long sleeves and trousers at dusk and dawn, when mosquitoes are most active. Travellers returning from countries where these viruses are endemic – most parts of Central America, South America, and the Caribbean – should maintain these precautions for at least three weeks after their return to Europe to prevent mosquitoes from biting them and spreading any viruses locally, the agency said. Other climate scientists say European countries grappling with the reemergence of mosquito-borne diseases should take lessons from regions where they have long been endemic, such as sub-Saharan Africa, Asia, and the Americas. 'In Europe, it's definitely a seasonal disease,' Semenza said. 'But we see the season expanding, and we'll see more and more cases'.

Greek authorities on alert after man dies of rare tick-borne illness

Health authorities in Greece are raising the alarm after a 72-year-old livestock farmer died of Crimean-Congo haemorrhagic fever. The man was infected by a tick and hospitalised in Larissa, where he transmitted the disease to his doctor, who now appears to be in good health. In all, 25 people have been quarantined because they were either close contacts or nursing staff who came in touch with the man who died. None have fallen ill, but 10 people belong to high-risk groups. Crimean-Congo haemorrhagic fever is a viral illness that spreads through tick bites. It is rare in Europe, but sometimes appears in the Balkan and Mediterranean countries. Greece last reported a case in 2018. More than 80 per cent of cases have no or mild symptoms, but among severe cases that require hospitalisation, about 30 per cent of patients will die from the disease, according to the European Centre for Disease Prevention and Control (ECDC). Symptoms can include fever, muscle and stomach pain, and dizziness, as well as nosebleeds and organ failure, the ECDC said. Since the man's infection was identified, Greece's public health officials have taken samples from humans and 15 ticks to conduct laboratory testing, with results expected in the next few days. They are also fumigating the area to reduce risks to people. The authorities have advised health workers to be vigilant about suspicious illnesses and are taking steps to inform high-risk groups about prevention measures, such as avoiding woods and meadows where ticks may be present, wearing light-coloured clothing to make it easier to spot ticks, and using insect repellant. To prevent person-to-person spread, public health authorities recommend that people avoid close physical contact with someone who may have hemorrhagic fever, wear gloves and protective equipment when caring for patients, and wash their hands regularly.
