In recent months, there has been a concerning uptick in pediatric hepatitis cases affecting children aged one to six, not only in the U.S. but also in countries like Spain, Denmark, the Netherlands, and the U.K. On May 6, the Centers for Disease Control and Prevention (CDC) announced an investigation into over 100 cases across various states. Reports indicate that more than 90 percent of these children required hospitalization, and tragically, five have died due to complications from the illness.
Health authorities, pediatricians, and parents are understandably on high alert as these cases have emerged suddenly and are causing serious illness in previously healthy children. However, experts emphasize that despite the alarming headlines, the likelihood of a child developing severe symptoms remains very rare. Most affected children are expected to recover fully. So, what should parents know about this unexpected surge in pediatric hepatitis? What symptoms should they be vigilant for? Can family pets be a source of transmission? To provide clarity on this situation, we consulted Dr. Emily Rivers, a pediatric specialist at Oakwood Medical Center, and Dr. Sarah Lee, a board-certified pediatrician and founder of KidsHealth Hub.
Understanding Hepatitis
Hepatitis, in simple terms, refers to inflammation of the liver. Dr. Rivers explains, “The term ‘hepatitis’ encompasses several specific viruses known to cause liver inflammation, such as Hepatitis A, B, C, D, and E.” Dr. Lee adds, “In children, hepatitis is typically linked to viral infections, toxins, medications, or certain medical conditions. While parents may be familiar with vaccines for Hepatitis A and B, hepatitis cases in children are uncommon, which is why this recent outbreak is garnering attention.”
Patterns of Reported Cases
The first cluster of these mysterious hepatitis cases was identified in early April in the U.K. Healthcare officials could not find commonalities in diet, travel, or exposure among affected children when ruling out typical hepatitis viruses. As of May 10, the World Health Organization (WHO) reported 348 probable cases in children across 20 countries, with 70 additional cases pending confirmation. Notably, a series of cases in Alabama from October to February, including two children requiring liver transplants, prompted the CDC to issue a nationwide alert regarding symptoms to monitor. However, no definitive cause or pattern linking the cases has been established.
Dr. Rivers noted, “These children were previously healthy, which makes this phenomenon unusual and concerning, prompting us to alert parents and public health officials.”
Potential Causes of the Outbreak
Local and national health officials are still investigating the outbreak, but Dr. Rivers indicates that hepatitis in children has existed prior to this event. It is often caused by viruses such as cytomegalovirus (CMV), Epstein-Barr virus (EBV), or adenovirus, which can lead to liver inflammation. Current suspicions point towards adenovirus 41, although certainty remains elusive, as not all hepatitis cases have tested positive for it. Hepatitis A and B have been ruled out.
Symptoms for Parents to Monitor
If your child becomes ill, keep an eye out for the following symptoms:
- Yellowing of the skin and eyes (jaundice)
- Nausea
- Diarrhea
- Vomiting
- Severe abdominal pain
- Fever
- Fatigue
- Loss of appetite
- Dark-colored urine
- Light-colored stools
- Joint pain
- Respiratory symptoms like a runny nose, cough, or pink eye
Dr. Lee stresses that the most concerning symptoms are jaundice and light-colored stools, which necessitate immediate medical attention. While more information is needed about this outbreak, both doctors agree there is currently no direct link to COVID-19 or the vaccine, as affected children were not vaccinated or symptomatic for COVID at the time of illness.
Regarding concerns that household pets might be involved in transmission, Dr. Rivers notes, “It’s important to conduct thorough investigations, but current evidence does not convincingly support this theory,” a sentiment echoed by Dr. Lee.
What to Do If You Suspect Hepatitis in Your Child
If you have concerns about your child’s health, Dr. Rivers recommends consulting your pediatrician. “Outbreaks of rare viruses do occur, and while vaccination can protect against many illnesses, hepatitis is usually caused by viruses we lack vaccines for. Prioritize good hygiene and stay connected with your healthcare provider if you’re worried. Remember, while serious, these cases remain very rare.”
Dr. Lee adds, “I don’t want parents to panic since it’s still relatively uncommon, but being aware of the signs and symptoms is important. Practicing good hygiene—like handwashing and being cautious in social settings—is always beneficial, especially given the ongoing pandemic.”

Summary
The rise in pediatric hepatitis cases is concerning but still considered a rare occurrence. Parents should monitor for specific symptoms and maintain good hygiene practices. Consulting with a pediatrician if there are concerns is essential, as outbreaks of rare viruses can happen. Staying informed and cautious is key during this time.
