Hi Doctor,My wife got an accidental prick after administering insulin to her mother who is currently down with liver failure due to water filling her stomach every few days.       I am also listing below her 63 year old (frail, weak and weighing 39Kgs/80lbs) moms medical histroy below for your ref
Good day, and thanks for your question.  From your story the only transmissible infection your wife can contract from her mother is Hepatitis C. Asthma, breast cancer and high sugar levels cannot be transmitted through needle prick. However, the risk of contracting hepatitis C via needle prick (insulin needle) is extremely low. No need to panic my dear brother. However, you can take her to the hospital, she will do a baseline test on Hepatitis C (Antioch and liver function test especially alpine amino transferase) and the test is repeated 4-6 weeks after. Hope it helps. Thank you.
