Hepatitis A Outbreak
Since January 1, 2017, Utah public health has identified 193 confirmed cases of hepatitis A virus (HAV) infection; many among persons who are homeless and/or using illicit drugs. Several cases have been linked by investigation and/or viral sequencing to a national outbreak of hepatitis A involving cases in California and Arizona. Hospitalization rates of less than 40% have been described in previous hepatitis A outbreaks; however, other jurisdictions associated with this outbreak are reporting case hospitalization rates approaching 70%. The high rate of hospitalization may be a result of cases having underlying illnesses (e.g., alcoholism), or a higher rate of hepatitis comorbidities (e.g., hepatitis B or C). In response to the outbreak, public health officials have been working to identify cases and contacts, provide education, and ensure opportunities for vaccination of close contacts to cases and vulnerable populations.
Hepatitis A is usually spread through having oral contact with items contaminated with hepatitis A, for example, through ingesting food or drinks contaminated by infected feces. Some people do not develop symptoms, even if infected. If symptoms occur, they usually appear anywhere from 2-6 weeks after exposure. Symptoms usually develop over a period of several days, and may include jaundice (the yellowing of the skin or whites of the eyes), abdominal pain, nausea or diarrhea. Hepatitis A vaccination is the best way to prevent hepatitis A infection. For more information on hepatitis A, click here.
