An outbreak of Hepatitis A in the Snoqualmie Valley has county health authorities asking people to get vaccinated.

Matias Valenzuela, public education coordinator with the county’s public health department, said his office has responded to six confirmed cases in the Valley, all in adults.

The nonlethal virus spreads easily, Valenzuela said in a press release, and it can spread through close contact with a person with hepatitis A.

The illness can spread when an infected person does not wash hands adequately after using the toilet and has close contact with others, or prepares food or drinks for others.
