If you have received the hepatitis A vaccine series, you do not need to be revaccinated.
People who ate at one of the restaurants during these dates who are not currently in the Grand Lake area are urged to contact their state or local public health department or their health care provider to obtain necessary shots.
Immune globulin and/or the hepatitis A vaccine can prevent infection if given within 14 days of exposure. People between ages 1 and 40 can receive hepatitis A vaccine; infants and people over 40 should receive immune globulin.
Workers at both restaurants were immunized with hepatitis A vaccine on Thursday as a precaution.
People who ate at these restaurants between July 10 and 23 may have been exposed but would not benefit from the immunizations because immunizations must be given within 14 days of exposure. These people should watch for signs of hepatitis A and contact their health care provider if they develop illness.
Early signs of hepatitis A appear 2-6 weeks after exposure. Symptoms commonly include mild fever, loss of appetite, nausea, vomiting, diarrhea, tiredness, pain in the upper right side of the abdomen, dark urine and jaundice (yellowness of eyes or skin).
The disease varies in severity, with mild cases lasting two weeks or less and more severe cases lasting 4-6 weeks or longer. Some individuals, especially children, may not develop jaundice and may have an illness so mild it can go unnoticed. However, even mildly ill persons can be highly infectious. Persons with symptoms suggestive of hepatitis should consult a physician immediately, even if symptoms are mild.
Hepatitis A virus is spread as a result of fecal contamination (fecal-oral route) and may be spread from person to person through close contact or through food handling. The virus is commonly spread by contaminated food or beverages. Persons are at increased risk of acquiring hepatitis A when they have been in close and continuous contact with an infected person.
