Hepatitis A is a virus that can cause fever, fatigue, loss of appetite, abdominal discomfort, dark urine, diarrhea, and yellow skin and eyes. Symptoms typically last several weeks to as long as two months. Hepatitis A virus is found in the stool of infected persons and is usually spread by eating contaminated food or drinking water, but can also be spread through close personal/sexual contact. Persons should seek medical attention immediately should they develop symptoms.

“Hepatitis A infection is a vaccine-preventable disease, and fortunately, most children and adolescents have been vaccinated as part of routine childhood vaccination recommendations,” said Health Director Dr. Virginia Pressler. “However, many adults have not been vaccinated and remain susceptible.”

State Epidemiologist Dr. Sarah Park added, “Healthcare providers have been informed and asked to notify us immediately if they have a patient they suspect may be infected. Treatment for hepatitis A infection is supportive only, and while most people will recover without complications, we are encouraging everyone to review their immunization record and talk to their healthcare provider about vaccination.”

Hepatitis A vaccine is readily available at local pharmacies. Two doses of hepatitis A vaccine, given at least six (6) months apart, are needed for lasting protection.

While vaccination provides the best protection, frequent handwashing with soap and warm water after using the bathroom, changing a diaper, or before preparing food can help prevent the spread of hepatitis A. Appropriately cooking foods can also help prevent infection.
