Hepatitis A outbreak in Kyiv: Over 30 infected, children mostly

An outbreak of hepatitis A has been recorded in Kyiv, affecting 33 people, including 19 children. According to the Center for Public Health, 25 of those infected - 15 of them children - have been hospitalized and are undergoing treatment at medical facilities in the capital.

The outbreak began in one of Kyiv’s districts, with initial reports of 15 cases. Thanks to prompt action by the Kyiv Center for Disease Control and Prevention (CDC), epidemiologists identified more than 200 people who had been in contact with the infected. Upon examination, another 18 cases were confirmed.

Water samples within norms

Specialists collected water samples from three schools, bottled water stored in shelters, and two district water wells. Lab tests for bacterial, chemical, and viral contaminants (including hepatitis A) all came back within normal limits. Students from affected schools have temporarily switched to remote learning.

The CDC emphasized that the epidemiological investigation is ongoing to determine the source and factors contributing to the spread of the infection. Relevant government agencies have been engaged in the process.

What is hepatitis A?

Hepatitis A is a viral liver disease that can cause mild to severe illness. The virus spreads through consumption of contaminated food or water and poor hygiene practices. It can survive for:

• 5 minutes at boiling temperatures;

• Up to a week in dry conditions at room temperature;

• 3–10 months in water;

• Up to 30 days in feces.

While nearly all infected individuals recover fully, there is a risk of severe, fast-developing cases that can be fatal. A person who recovers from hepatitis A gains lifelong immunity.

Transmission and symptoms

Common transmission routes include:

• Consuming contaminated water or food;

• Poor personal hygiene;

• Food prepared by an infected person;

• Certain sexual activities.

The incubation period is typically 14–28 days. Symptoms can range from mild to severe and include:

• Fatigue and weakness;

• Fever;

• Loss of appetite;

• Diarrhea and vomiting;

• Abdominal discomfort, especially in the upper right side;

• Dark-colored urine;

• Jaundice (yellowing of the skin and eyes), seen in 70% of adults.

Not all infected individuals exhibit symptoms, so if you’ve been in contact with someone with hepatitis A, consult your doctor and get tested.
