Over 200 mothers warned after hepatitis B exposure at Sydney Hospital

Australia's New South Wales Health has issued a warning after it was revealed that more than 200 mothers may have been exposed to hepatitis B at Nepean Hospital in Sydney over an 11-year period.

The exposure is linked to a healthcare worker in the Birth Unit who was infectious with the virus between 2013 and 2024.

A total of 223 women who gave birth at the hospital during this time may have experienced "potential low-risk exposure" to the virus, NSW Health officials confirmed.

The hospital has also reviewed the care provided to 143 children who could have been affected.

The exposure is thought to have occurred during certain medical procedures performed by the infected worker.

These include episiotomies, repairs for vaginal or perineal tears, and the application of fetal scalp electrodes on both mothers and babies. Health authorities are reaching out directly to patients who underwent these procedures.

NSW Health assured the public that the risk of transmission is considered low, but out of an abundance of caution, they are offering free hepatitis B testing and assessment to the affected women and children. "The risk of transmission has been determined to be low for the 223 women and 143 children," said the NSW Health Blood Borne Viruses Advisory Panel.

In a statement, the Nepean Blue Mountains Local Health District (NBMLHD) expressed regret over the potential distress caused, offering their sincerest apologies to those impacted by the exposure. They reassured future patients that the hospital continues to maintain high standards of care and safe birthing environments.

Hepatitis B is a serious liver infection caused by the hepatitis B virus, which can be transmitted during birth, sexual contact, or blood-to-blood contact. NSW Health emphasized the importance of testing for the virus, as there are treatments available that can prevent long-term complications and limit the spread of the infection.

For those unsure about whether they may have been exposed, a dedicated support line is available at 1800 716 662 for further information and advice. The best defense against hepatitis B is vaccination, and testing is crucial for early detection and treatment.
