| hepatitis A | <virology> A form of viral hepatitis, known as infectious hepatitis, due to its ability to be spread through personal contact with oral secretions or stool. Virus will be shed in the stools of an infected individual 2-3 weeks prior to the onset of any symptoms. Hepatitis A may also be transmitted sexually. Symptoms are similar to those of influenza, but the skin and eyes may become yellow. Recent travel to a third world country is a risk factor. There is no specific treatment but infected individuals should avoid potentially hepatotoxic substances. The virus is a small (27nm diameter) single stranded RNA virus with some resemblance to enteroviruses such as polio. (27 Sep 1997) |
| hepatitis a immunization | When immediate protection against hepatitis a (infectious hepatitis) is needed, immunoglobulins are used. Protection is effective only if given within 2 weeks of exposure and lasts but 2-4 months. Immunoglobulins can be used to protect household contacts of someone with acute viral hepatitis and travelers to regions with poor sanitation and high hepatitis a rates, when the traveler has to depart sooner than the vaccines can take effect (about 2 weeks). Travelers can receive the immunoglobulin and vaccine simultaneously and be protected immediately and for longer term. When immediate protection is not needed, hepatitis a vaccines are considered for individuals in high-risk settings, including frequent world travelers, sexually active individuals with multiple partners, homosexual men, individuals using illicit drugs, employees of daycare centres, and certain healthcare workers, and sewage workers. Two hepatitis a vaccines called havrix and vaqta are commercially available in the u.s. Both are highly effective and provide protection even after only one dose. Two doses are recommended for adults and 3 doses for children (under 18 years of age) to provide prolonged protection. (12 Dec 1998) |
