“Hepatitis A is spread by unknowingly getting the virus in your mouth after touching or eating items that are contaminated with small amounts of stool from an infected person,” said Beth Daly, Chief of the Bureau of Infectious Disease Control. "Hepatitis A can also spread from close personal contact with an infected person or caring for someone who is ill."
Daly said the disease is preventable "with a safe and effective vaccine, which she said is vitial to stopping the outbreak.
"People at high risk for infection should talk with their healthcare provider about getting vaccinated," Daly said.
The department said people at highest risk of contracting the virus are:
• people with direct contact with someone with hepatitis A<br/> • people using injection or non-injection recreational drugs, including marijuana<br/> • people experiencing homelessness or with unstable housing (e.g. "couch surfing")<br/> • gay and bisexual men <br/> • people with ongoing, close contact with high-risk individuals
Symptoms of the disease include fever, tiredness, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain and jaundice, which is the yellowing of the skin and eyes.
