Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, pursuant to the Answer of 24 November 2025 to Question 91494, if the UK Health Security Agency will publish its assessment of the need for mandatory notification for Group B Streptococcus.

The UK Health Security Agency (UKHSA) plays a key role in addressing group B streptococcus (GBS) infection both through routine service activities and innovative research.

The UKHSA does not believe that there is a rationale at present for GBS being added to the Health Protection Notification Regulations. There are no immediate and specific public health actions required to be taken in response to a case being diagnosed. Whilst periods of enhanced surveillance suggest routine surveillance may be underestimating numbers of infections, this has not been audited to identify the source and reason for discrepancies between different sources of reports during these periods. Given the largely automated nature of laboratory surveillance, making GBS notifiable would not necessarily address any deficits in reporting.

The list of notifiable disease is kept under review by the Department with the UKHSA involvement. Further information is available at the following link:
