Naples, Italy is currently grappling with a significant surge in hepatitis A cases, placing considerable strain on the city’s healthcare system. As of March 18, 2026, Cotugno Hospital, a key medical facility in the region, is reporting 43 patients hospitalized with the infection, a number that represents a substantial increase compared to typical seasonal trends. The situation has develop into so acute that some patients are being treated on stretchers in the emergency room due to a lack of available beds, highlighting the severity of the outbreak and the urgent need for public health intervention.
The recent spike in cases has prompted health officials to launch an investigation into the cause, with initial focus centering on the potential link to the consumption of raw seafood. Hepatitis A, a viral infection affecting the liver, is typically transmitted through the fecal-oral route – meaning it’s contracted by ingesting contaminated food or water, or through close contact with an infected individual. While a vaccine is available for both children and adults, the current outbreak underscores the importance of preventative measures and public awareness. The age range of those hospitalized is primarily between 35 and 45 years old, suggesting a pattern that warrants further epidemiological study.
Rising Case Numbers and Hospital Strain
The situation at Cotugno Hospital is particularly concerning. Reports indicate that the hospital is experiencing an unusual level of overcrowding, with patients being accommodated in non-traditional spaces like emergency room hallways. According to reports from Il Mattino, approximately 50 individuals have been hospitalized with hepatitis A within the last 15 days alone. This rapid increase has overwhelmed the hospital’s capacity, forcing medical staff to adapt and prioritize care in challenging circumstances. One particularly severe case involved a 46-year-old man who developed severe liver failure as a complication of the infection and required transfer to Cardarelli Hospital for evaluation for a potential liver transplant, demonstrating the potentially life-threatening nature of the disease.
The regional government of Campania has responded by intensifying control measures along the entire supply chain of mollusks and bivalves, aiming to prevent further contamination. These measures include increased inspections and enhanced surveillance to ensure food safety standards are being met. The region is also focusing on public health education, aiming to inform citizens about the risks associated with hepatitis A and the steps they can take to protect themselves. As of March 18, 2026, a total of 133 cases have been recorded this year, prompting officials to emphasize the need for vigilance and proactive measures.
Understanding Hepatitis A: Transmission and Symptoms
Hepatitis A is an acute infection of the liver caused by the hepatitis A virus (HAV). The virus is shed in the feces of infected individuals, even before symptoms appear, making it easily transmissible. The incubation period, the time between exposure and the onset of symptoms, typically ranges from 15 to 50 days. Symptoms can vary in severity, ranging from mild flu-like illness to more serious liver damage. Common symptoms include fatigue, nausea, vomiting, abdominal pain, jaundice (yellowing of the skin and eyes), dark urine, and pale stools.
The Centers for Disease Control and Prevention (CDC) outlines several key preventative measures against hepatitis A, including practicing good hygiene, such as thorough handwashing after using the restroom and before preparing food. It also recommends avoiding consumption of raw or undercooked shellfish, particularly when traveling to areas with high rates of hepatitis A. Vaccination remains the most effective way to prevent infection, and is recommended for individuals at increased risk, including travelers to endemic areas, people who leverage illicit drugs, and those with chronic liver disease.

The Role of Seafood Consumption
The current outbreak in Naples has raised concerns about the potential role of contaminated seafood, particularly raw or undercooked shellfish. Health authorities are actively investigating this possibility, conducting inspections of seafood vendors and restaurants to ensure compliance with food safety regulations. The Federazione Nazionale degli Ordini dei Biologi has noted that hepatitis A cases traditionally increase during the winter months, often linked to the consumption of raw seafood during the holiday season. This suggests that the current surge may be related to seasonal patterns, but further investigation is needed to confirm this link.
Experts emphasize the importance of thoroughly cooking shellfish to kill the virus. Individuals who consume raw or undercooked seafood should be aware of the potential risks and take appropriate precautions. The regional government’s intensified control measures aim to minimize the risk of contamination and protect public health. The investigation is focusing on identifying the source of the contamination and implementing measures to prevent further spread of the virus.
Regional Response and Public Health Recommendations
The Campania region has mobilized a comprehensive response to the outbreak, involving the Departments of Prevention of the local health authorities (ASL), the Zooprophylactic Experimental Institute of the South, and a network of technical and scientific experts. This coordinated effort aims to strengthen surveillance, improve food safety, and enhance public awareness. The regional government is also providing guidance to healthcare providers on the diagnosis and management of hepatitis A cases.
For individuals concerned about potential exposure, health officials recommend consulting a physician for testing and vaccination. Early diagnosis and vaccination can significantly reduce the risk of developing severe complications. The public is also urged to practice good hygiene, including frequent handwashing, and to avoid consuming potentially contaminated food or water. Staying informed about the outbreak and following public health recommendations are crucial steps in protecting oneself and the community.
The situation remains fluid, and health authorities are continuing to monitor the number of cases and assess the effectiveness of the implemented control measures. Further updates will be provided as the investigation progresses. The next official update from the Campania regional health authority is expected on March 25, 2026, where they will present preliminary findings from the ongoing investigation into the source of the outbreak.
This outbreak serves as a critical reminder of the importance of robust public health infrastructure, vigilant food safety practices, and proactive preventative measures. The health and well-being of the community depend on a collective effort to address this challenge and protect against future outbreaks.
