An sudden spike in hepatitis A infection in several European countries has led to public health authorities issue urgent advisories and roll out containment strategies. The multicountry outbreak, spanning Austria, Czechia, Hungary, and Slovakia, has already infected more than 2,000 people since January 2025. The European Centre for Disease Prevention and Control (ECDC) confirmed on Friday that two genetically linked strains of the hepatitis A virus (HAV) are behind this multicountry outbreak, which alarms for ongoing community transmission and potential cross-border spillover.

Though hepatitis A is generally a preventable viral illness, its comeback in Europe is a grim reminder of how vaccination gaps, sanitation flaws, and outreach failures can prove lethal — particularly for older people and those who are vulnerable.

This outbreak, characterized by two similarly linked hepatitis A virus (HAV) strains, has not only affected local groups but also infected tourists traveling to popular tourist destinations in Europe. The problem is further complicated by reports of confirmed cross-border transmissions, with Germany reporting cases genetically associated with those in Austria and Hungary, indicating the likelihood for wider spread.

The cluster is focussed in four middle European countries: Slovakia (880), Czechia (600), Hungary (530), and Austria (87). Although all these countries have suffered the majority of the infections, cases that had the outbreak strain are also found within Germany, reflecting the virus's capacity to transcend borders via social networks and travel.

Nine fatalities have been reported to date — six in Czechia and three in Austria — underlining the potentially serious health impact of the disease, especially in older people or those with existing liver disease. The ECDC's rapid risk assessment also verifies genomic evidence of regionally linked transmissions, triggering a coordinated EU response.

What is Hepatitis A?

Hepatitis A is acute viral disease of the liver due to the hepatitis A virus (HAV). In contrast to its more persistent cousins, hepatitis B and C, hepatitis A does not result in chronic liver disease. But it can nevertheless generate full-blown disease and death—particularly among those at high risk.

The virus is mainly spread by ingestion of infected food or water, or direct contact with an infected person. HAV is found in the feces of infected individuals and is thus majorly a factor of poor sanitation and hygiene that leads to outbreaks. The illness quickly spreads in communities lacking clean water, safe food, and proper healthcare.

Contrary to hepatitis B and C, hepatitis A does not develop into chronic liver disease. Nevertheless, it may cause severe liver complications and even death in some people. Severity escalates with age. The ECDC has estimated the risk of serious illness as high in people older than 40 years and very high in individuals with pre-existing liver disease or weakened immunity.

Symptoms and Challenges in Early Detection

Not all people who get hepatitis A develop symptoms. But if symptoms do occur, they might include:

• Weakness and fatigue
• Abdominal pain and fever
• Jaundice, or yellow eyes and skin
• Clay-colored stools and dark urine
• Nausea and loss of appetite
• Diarrhea and joint pain

Since the virus takes weeks to manifest as symptoms, people may spread the virus unknowingly during incubation. That timing makes it harder to track the infections and contain possible routes of exposure.

Who Is Most at Risk?

Although anyone can get hepatitis A, there are groups that are more likely to suffer from severe illness. The ECDC states that individuals aged 40 years and older are at greater risk of developing serious complications, and the risk increases with age. Patients with existing liver disease and those who are immunosuppressed are especially at risk, as are older persons.

Social determinants also come into play. The epidemic has hit disproportionately hard among those living in homelessness, those who inject or use illicit drugs, and those living in filthy conditions or with limited healthcare access. These individuals usually do not have the resources necessary to receive vaccination or be at a hygiene standard to avoid infection.

For the population at large in the affected nations, risk is at present estimated as low to moderate. Yet, the situation is dynamic, and the risk for further transmission cannot be ruled out.

Slovakia has been struggling with hepatitis A since 2022, making it the epicenter of the current outbreak. Its 880 cases this year represent the largest burden across the affected nations. Czechia, meanwhile, has seen a significant jump in cases in 2025, including the majority of the deaths.

Even with the fewer cases reported, there have been three deaths in Austria — highlighting the fact that the virus does not have to be widespread to pose a threat. In Hungary, more than 500 cases of infection have been reported this year, leading health authorities to increase surveillance and prevention measures.

How the Virus Is Spreading?

Genetic sequencing has shown that the current outbreak is being fueled by person-to-person transmission in interconnected social networks and geographic regions. The fact that genetically similar strains were detected in Germany, where it is not an epicenter, is a testament to the ease with which the virus can travel across borders—particularly in an age of high mobility and international travel.

Though foodborne transmission cannot be ruled out, available evidence implicates close personal contact and unsatisfactory sanitation as main movers. This underscores the pivotal role that focused prevention and swift response play in high-risk populations.

The ECDC has called on member states to carry out epidemiologic studies, expand targeted contact with high-risk groups, and improve access to vaccination. Cross-border coordination has also been highlighted by the agency, since the outbreak does not respect geography or citizenship. Strategies that are recommended include:

• Targeted vaccine campaigns among high-risk groups
• Post-exposure prophylaxis (PEP) of close contacts
• Increased sanitation and hygiene in settlements and communities
• Increased genetic testing to track spread of virus
• Public education and awareness to increase early reporting and vaccination rates

ECDC's head of One Health Unit Ole Heuer highlighted the need for increased outreach: "This outbreak is a reminder that hepatitis A infection can lead to severe illness and death, particularly in individuals with poor access to health care and basic hygiene. Vaccination and sanitation services need to reach those who are most vulnerable."

How You Can Protect Yourself?

For people, the best defense against hepatitis A is vaccination. The hepatitis A vaccine is given in two doses, usually six to twelve months apart. The CDC says getting the vaccine — or immune globulin treatment — within two weeks of infection can ward off illness. Other important prevention measures are:

• Washing hands frequently with soap and water, particularly before meals
• Drinking clean, filtered water and avoiding suspect food sources while abroad
• Not getting direct exposure to the body fluid of infected people

The CDC also advises travelers to countries with outbreaks of hepatitis A to get vaccinated before they go.

As the peak travel season for summer draws near, it's a time of vigilance for public health officials and travelers alike. Vaccination, education, and enhanced sanitation are the pillars of prevention—not only for hepatitis A, but for the countless infectious diseases that still threaten global health security.

The World Health Organization (WHO) recommended that vaccine manufacturers must change the three strains included in the vaccines for the Northern Hemisphere's next influenza season. The WHO recommended that the vaccines for the next flu season must include the new variant of the influenza virus that increased last fall too late to be included in this winter's flu shots.

As of now with the technology available, companies need at least six months time to prep for new flu shots in time for immunization campaigns beginning in the late summer or early fall.

What Is The New Strain That WHO HAs Recommended To Be Included In Vaccine Shots?

Researchers first found out about the new variant in October after this season's flu shot was already out and distributed. This was the A (H3N2) subclade K. As per Danuta Skowronski MD, a flu researcher at the British Columbia Centre for Disease Control in western Canada, this led to a mismatch in the vaccines that went into people's arms and the viruses circulating around them.

While vaccines manufactured for the Southern Hemisphere were updated as compared to those distributed in the US last year, subclade K also appeared too recently. In the Southern Hemisphere, including Australia and South Africa, flu season runs from April to October. The highest number of cases and peak activity is seen between June and September.

More About Subclade K

The A (H3N2) subclade K, also known as the "super flu" is the new version of H3N2, which has been circulated worldwide this year "acquired 7 new mutations over the summer," said Antonia Ho, a consultant in infectious disease at Scotland's University of Glasgow. As per her media statement, this "means the virus is quite different to the H3N2 strain included in this year's vaccine".

Does That Mean Earlier Flu Shots Were Useless?

Many scientists and public health experts were worried that the current flu shots in circulations used in Northern Hemisphere were useless against the subclade K. However, Skowronski says that the vaccine, in fact, worked better than imagined.

Many other experts, William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, in Nashville, Tennessee, as reported by NBC, said, “Decades of data show that even when the match isn’t perfect, the flu shot continues to prevent hospitalizations, ICU admissions, and helps keep people out of the cemetery."

In an interim report released earlier this month, researchers found that the latest flu vaccine sin Canada reduced the risk of illness caused by influenza A (H3N2) viruses and severe enough to require an outpatient medical visit by 40 per cent as compared with the risk faced by unvaccinated people.

Strains Recommended For Fall Flu Shots

The WHO recommended different strains on how the latest flu shots will be manufactured. For instance, some traditional vaccines are based on viruses grown in eggs, whereas new vaccines are made in cell cultures or use recombinant or nucleic acid based technology.

The recommendation for egg-based vaccines are:

• an A/Missouri/11/2025 (H1N1)pdm09-like virus;
• an A/Darwin/1454/2025 (H3N2)-like virus; and
• a B/Tokyo/EIS13-175/2025 (B/Victoria lineage)-like virus.

The recommendation for cell culture-, recombinant protein- or nucleic acid-based vaccines are:

• an A/Missouri/11/2025 (H1N1)pdm09-like virus;
• an A/Darwin/1415/2025 (H3N2)-like virus; and
• a B/Pennsylvania/14/2025 (B/Victoria lineage)-like virus.

A recent study by the Indian Council of Medical Research (ICMR) showed that more than 40 percent of prostate cancer patients in the country are diagnosed after the cancer has spread.

The 43 percent of late diagnosis cases indicates the significant burden of late detection of prostate cancer in the country. This can not only limit treatment options but also lead to poorer survival outcomes.

The study, published in the Indian Journal of Surgical Oncology, revealed that while more than 80 per cent began treatment within two months, but referral patients experienced longer delays.

Researchers from the ICMR’s National Centre for Disease Informatics and Research, in Bengaluru, stressed the need to strengthen referral pathways to ensure timely, stage-appropriate care.

“Our study indicates that over 80 percent of patients commence treatment within two months of diagnosis, but referral systems and delays in care persist,” said corresponding author Prashant Mathur, Director, ICMR-NCDIR, in the paper.

“To address these challenges, the healthcare system must prioritize improving referral efficiency, reducing administrative bottlenecks, enhancing coordination through digital health records, and multidisciplinary tumor boards,” the authors added.

Age, The Strongest Risk Factor For Prostate Cancer

The ICMR study is based on an analysis of 9,347 cases from 96 hospitals under the National Cancer Registry Program.

The researchers found that 75.6 percent of total prostate cancer cases occurred in the age group of 60–80 years, indicating that advanced age remains the biggest risk factor for the condition.

As life expectancy increases, more men reach the higher-risk age group, but awareness and screening practices have not scaled proportionately.

Adenocarcinoma was the most common pathology, constituting 77 percent of cases.

It is the most common form of prostate cancer, accounting for over 95 per cent of all cases. It develops in the gland cells that produce prostate fluid and typically grows slowly over several years.

Further, the ICMR researchers noted that about 57 percent of cases were diagnosed with localized (29.9 percent) or locoregional (27 percent) cancer.

Thirty percent underwent surgical treatment, and 22 percent received radiation therapy. Systemic therapy was the most common single modality treatment.

“Early detection and streamlined referral pathways are essential to improve prostate cancer outcomes in India,” the researchers said.

Prostate Cancer And Its Prevalence In India

Prostate cancer forms in the cells of the prostate -- a gland found only in males and a part of the male reproductive system. It lies below the urinary bladder and in front of the rectum.

Nearly all prostate cancers develop from glandular cells (adenocarcinomas).

Globally, prostate cancer is the most frequently diagnosed cancer among men in 112 countries and the leading cause of cancer death in 48 countries. In 2020, an estimated 1.4 million new cases of prostate cancer and 0.37 million deaths were reported worldwide.

In India, it is the second most common cancer among men, accounting for more than 60 percent of the prostate cancer burden in South-Central Asia. As per the ICMR data, the country reported 34,540 incidences of prostate cancer and 16,783 deaths.

Prostate cancer symptoms include urinary difficulty, a weak stream, or blood in the urine.

As prostate cancer is a slow-developing disease, it often causes no symptoms during the early-stage, leading to delayed medical consultation.

Other reasons for late detection in India include low awareness, limited routine screening -- PSA (prostate-specific antigen) programs; social stigma and hesitation due to embarrassment or cultural taboos.

Lack of access to specialist care, diagnostic facilities, and cancer centers, especially in rural populations, coupled with cost and referral gaps, also leads to delay in diagnosis.

In a shocking video, a woman who ordered packaged eggs sold by Eggoz from Zepto claims they were filled with plastic-made strands instead of yolk, however the brand soon quoted FSSAI's rules and issued a clarification.

Earlier this week, Shalini Singh shared an Instagram video of six eggs that appear to have yellow, thread-like strands emerging from within, suggesting that instead of slimy yolk, she found a plastic substance bursting out of the eggs after boiling them.

In the clip, the visibly upset customer is heard saying: “Until now we had only heard that fake eggs or plastic eggs were being sold in the market, but today I witnessed an example in my own home. I ordered Eggoz Everyday brand eggs from Zepto and as soon as I put them on to boil, instead of yolk, plastic started coming out from inside."

Pointing at the cracked eggs, she added, “You can see in the video yourself, plastic is coming out in the form of noodles. Each egg has the Eggoz Everyday stamp on it. Look at how plastic fake eggs are reaching our homes.

“This is what we are buying today. If they had been cooked in another way, we might not even have realized we were consuming plastic. These boiled eggs burst, and that is how we found out it was plastic. If this is the condition of such big brands today, what is even left safe to eat?"

Can Egg Yolks Be Filled With Plastic?

"Consumers need to remember that the quality and appearance of the egg mostly depend on the way they are stored and for how long they are stored. Egg quality is best maintained when they are stored in cold temperatures preferably inside refrigerators and consumed within a period of 2 to 3 days.

"When kept in room temperature, several changes take place in an egg that bring about differences in the smell, texture and appearance of the egg."

The FSSAI further suggested holding up an egg against a very bright light in a dark room to detect its age. If its fresh, the egg will display a small air gap usually at the broader (blunt) end and if its starting to age, the air cell will expand in volume.

Upon hard boiling a fresh egg, you can clearly see the indentation left behind at the top of the egg once the shell is peeled off.

When fresh eggs are boiled, the yolk normally stays in the center and is not very mobile because of the chalaza (the strings of tissue) that hold it in place. These strings break down as the egg ages (during storage or transportation). When hard boiled eggs are cut length wise, one can see that the yolk has moved off the centre.

What Did The Company Say?

"Thank you for bringing this to our attention."

They also reached out with an official clarification, stating that there is no such thing as plastic eggs and that the claims stem from common misconceptions, quoting FSSAI's guidance.

In an official statement, the brand commented: "There are no plastic eggs. Eggs are a natural agricultural product, and variations in texture or appearance may occur due to storage or temperature conditions at different stages after production. Such natural changes do not indicate the presence of artificial or plastic material and do not affect food safety."

The company also highlighted its commitment to strict farm-to-shelf quality processes, including hygienic handling, batch traceability and temperature-controlled logistics.
