Newport, Wales: A sterilization lapse at a National Health Service hospital in Wales has led to 21 patients being identified as at risk of exposure to blood-borne viruses, including HIV, hepatitis B, and hepatitis C. The issue was identified in March 2026 during an internal review.
The incident occurred at the Royal Gwent Hospital in Newport, which is managed by Aneurin Bevan University Health Board. According to official statements and multiple reports, the affected patients underwent minor procedures, including orthodontic treatments such as brace fitting, where medical instruments did not undergo the full sterilization process.
Hospital staff used instruments that had undergone cleaning and disinfection but had not been fully sterilized. Sterilization is a critical step that eliminates all microorganisms, including viruses and bacterial spores. Disinfection reduces microbial load but does not ensure complete elimination of infectious agents.
The health board identified the issue during an internal review of decontamination processes. Reports indicate that the lapse involved a failure to complete the final stage of the sterilization cycle for certain reusable instruments.
Following this discovery, officials traced affected cases and contacted 21 patients who underwent procedures during the identified period.
The health board stated that the risk of transmission of blood-borne viruses is considered extremely low. As a precaution, all affected patients have been offered blood tests to screen for HIV, hepatitis B, and hepatitis C. Patients may require follow up testing over time, as some infections may not be immediately detectable after exposure.
According to reports, some individuals were notified around two to three weeks after their procedures. This delay in informing patients has raised concerns about communication, transparency, and patient safety. The health board has acknowledged the delay and stated that it is reviewing its patient notification protocols.
Reports from International Business Times and other outlets indicate that concerns about sterilization practices were raised internally before the incident was formally recognized. A whistleblower reportedly highlighted issues related to equipment handling and adherence to sterilization procedures.
The health board has confirmed that an internal investigation is underway. It has also reported the incident to relevant regulatory bodies and is conducting a broader review of its decontamination systems.
Reports indicate that at least one of the affected patients was a teenager who underwent a dental or orthodontic procedure. The case has drawn attention due to the involvement of young patients and the nature of the exposure risk.
The lapse involved reusable medical instruments rather than single use instruments. Authorities have not reported any confirmed transmission of infection linked to this incident.
Blood-borne viruses such as HIV, hepatitis B, and hepatitis C spread through contact with infected blood or certain body fluids. In healthcare settings, improper sterilization of instruments can allow transmission if contaminated equipment is reused between patients.
The likelihood of transmission depends on several factors, including whether any instrument was contaminated with infected blood, the type of procedure performed, and the extent of tissue exposure. Although the risk in this case is considered extremely low, testing is recommended as a precaution due to the serious nature of these infections.

Aneurin Bevan University Health Board has apologised to the affected patients and stated that patient safety remains a priority. The board stated that it has taken immediate corrective actions, including reinforcing sterilization protocols, reviewing equipment handling procedures, and providing additional staff training.
The board continues to monitor the situation and has stated that no confirmed cases of infection linked to this incident have been identified so far.
