Case of hepatitis A

There has been a case of hepatitis A which has resulted in potential exposure in one of the residences at Western University. Close contacts have been offered the hepatitis A vaccine to decrease the risk of acquiring infection.

Importance of suspecting the diagnosis and reporting to the Health Unit

It is very important for hepatitis A to be reported to the Health Unit as soon as it is suspected so that post-exposure vaccination with the hepatitis A vaccine can be administered to close contacts as soon as possible. Delays in the administration of the hepatitis A vaccine after an exposure can lower its ability to prevent subsequent infection.

When considering the diagnosis of hepatitis A, it should be noted that risk factors such as recent travel (within the 2 to 6 weeks before onset of symptoms), or exposure to a known case may be present, but people with no obvious risk factors can also develop hepatitis A.

The Health Unit can be reached at 519-663-5317 ext. 2330.

Symptoms

Symptoms of hepatitis A included: fever, loss of appetite, nausea, abdominal pain and malaise. A few days later, jaundice can develop, along with dark urine and pale stools. The incubation period for hepatitis A can range from 2 to 6 weeks.

Blood test

If hepatitis A is suspected, please order a STAT IgM to Hepatitis A and contact the Health Unit. Hepatitis B (HBsAg, anti-HBs, IgM hepatitis B core, total anti-hepatitis B core) and hepatitis C (anti-HCV) should be ordered as well if these are also suspected. Please do not wait for the hepatitis A test results to contact the Health Unit.
