Health authorities in New South Wales are issuing an urgent call for former patients of a Strathfield dentist to undergo screening for blood-borne viruses, following a discovery of systemic failures in infection control and patient record-keeping.
NSW Health has warned that up to 5,000 people who visited the practice of Dr. William Tam over the last 25 years may have been exposed to hepatitis B, hepatitis C, and HIV. The alert comes after an inspection revealed that the clinic, located at Suite B, 2 Albert Road, Strathfield, failed to maintain the rigorous sterilization and documentation standards required for dental surgery.
The situation is complicated by a critical administrative failure: the absence of comprehensive patient records. Because Dr. Tam did not maintain an accessible list of those treated at the clinic, health officials are unable to contact potentially exposed individuals directly, turning a targeted medical recall into a broad public health appeal.
As a physician, I recognize that the phrase “low risk” can often lead patients to dismiss a warning. However, in the context of blood-borne pathogens, low risk does not mean no risk. The danger lies in the asymptomatic nature of these viruses; many individuals can carry hepatitis or HIV for decades without a single outward symptom, while the viruses silently cause damage to the liver or immune system.
A Failure of Clinical Governance
The investigation into the Strathfield practice began following a complaint lodged with the Dental Council of NSW. The complaint centered on two primary concerns: substandard infection control practices and a failure to maintain proper patient records. Infection control in dentistry is not merely a guideline but a life-saving necessity, as the environment involves frequent contact with blood and saliva through invasive procedures.
Following the inspection by health authorities, Dr. Tam retired and is no longer a registered dentist. This departure, coupled with the missing records, has left NSW Health in the tricky position of having to rely on public awareness to identify at-risk individuals.
Dr. Leena Gupta, clinical director of public health at the Sydney Local Health District, emphasized that the window of exposure spans more than a quarter of a century. This means patients who visited the clinic in the late 1990s or early 2000s are just as relevant to this warning as those seen more recently.
Understanding the Blood-Borne Risks
When sterilization protocols fail—such as the improper autoclaving of instruments or the reuse of single-use needles—pathogens can be transferred from one patient to another. The three viruses of concern in this case have very different clinical profiles, but all require professional screening for detection.
Hepatitis B (HBV) is a highly contagious liver infection. While some people recover completely, others develop a chronic infection that can lead to cirrhosis or liver cancer. Fortunately, a vaccine is available, and chronic cases can be managed with medication.
Hepatitis C (HCV) is primarily transmitted through blood-to-blood contact. Unlike Hepatitis B, there is no vaccine, but the medical landscape for HCV has changed dramatically in recent years. Modern direct-acting antiviral (DAA) treatments can now cure the vast majority of Hepatitis C infections with a short course of oral medication and minimal side effects.
HIV (Human Immunodeficiency Virus) attacks the body’s immune system. Without treatment, it progresses to AIDS. However, with early detection and antiretroviral therapy (ART), people living with HIV can lead long, healthy lives and reduce their viral load to undetectable levels, meaning they cannot transmit the virus to others.
| Virus | Primary Risk | Prevention/Treatment | Symptom Timeline |
|---|---|---|---|
| Hepatitis B | Chronic Liver Disease | Vaccine & Management | Days to Decades |
| Hepatitis C | Cirrhosis/Liver Cancer | Curable via Antivirals | Often Asymptomatic |
| HIV | Immune System Failure | Lifelong ART Therapy | Variable/Long-term |
Steps for Former Patients
If you received dental treatment at Suite B, 2 Albert Road, Strathfield, from Dr. William Tam at any point over the last 25 years, NSW Health advises you to take the following steps immediately:
- Schedule a GP Appointment: Visit your general practitioner or a healthcare provider and explicitly mention that you were a patient of Dr. William Tam in Strathfield.
- Request a Full Screen: Ask for specific blood tests for HIV, Hepatitis B, and Hepatitis C.
- Review Your History: If you have had these tests in the last few months for other reasons, check your results, but consult your doctor to ensure the tests were comprehensive enough.
- Utilize Official Resources: NSW Health has provided detailed fact sheets on these viruses to help patients understand what to expect during testing.
For those who are anxious about the process, it is crucial to remember that testing is a simple blood draw. The goal of this public health initiative is early detection; the sooner a virus is identified, the more effective the intervention.
Patients seeking further guidance can contact their GP or utilize the Healthdirect service for initial triage and information.

NSW Health continues to monitor the situation and is working to identify any other gaps in the patient registry. Further updates regarding the clinical audit of the Strathfield practice are expected as the Dental Council of NSW concludes its review of the case.
