At least three people in Clarke County, AL, have fallen ill with Hepatitis A, according to the Alabama Department of Public Health. The health department is investigating how the patients might been sickened. Two of the individuals reportedly have a history of international travel. Hepatitis A is a contagious liver disease caused by the Hepatitis A virus, most commonly contracted from food or drinks contaminated with infected fecal material. Symptoms of Hepatitis A typically develop 15 to 50 days after infection and include fatigue, nausea, abdominal pain, loss of appetite and jaundice. While most cases resolve themselves within two weeks, severe cases can last for a month or more. A Hepatitis A vaccine can help prevent symptoms from developing if received within two weeks of infection if the patient believes they might have been exposed to the virus. Those who have received a vaccine in the past are not at risk of developing symptoms. Anyone who suspects they or a family member contracted a Hepatitis A infection are encouraged to contact a healthcare provider.
