Notifiable diseases and how to report them
Source: gov.uk (2025-04-29)

Notifiable diseases in humans that medical practitioners must report and how to report them.

Registered medical practitioners must report a notifiable disease to the UK Health Security Agency (UKHSA, previously Public Health England).

Notifiable diseases are certain infections that may present a risk to human health. Check the list of notifiable diseases (#list-diseases).

How to report a suspected notifiable disease

If the case is an urgent notifiable disease (#list-diseases), you must report it by telephone to your local UKHSA health protection team (https://www.gov.uk/health-protection-team) within 24 hours. This is to discuss actions to protect public health.

Report all cases on the Report a notifiable disease online service (https://www.gov.uk/guidance/report-a-notifiable-disease) within 3 days.

Do not wait for laboratory confirmation of the disease. By law, you must report any suspicion of a notifiable disease.

Diseases you must report

You must report any suspected case of a notifiable disease.

A case may be urgent if:
- it’s part of a current outbreak
- the suspected disease is uncommon in the UK
- the suspected disease spreads easily, or its spread is hard to control
- the patient is high risk, for example because of their age or job
If you are not sure if the case is urgent, telephone your local UKHSA health protection team (https://www.gov.uk/health-protection-team).

You can download and print the list of notifiable diseases on a poster (https://www.gov.uk/government/publications/notifiable-diseases-poster-for-registered-medical-practitioners) for your practice or setting.

Reporting other infectious diseases

You can use the Report a notifiable disease online service (https://www.gov.uk/guidance/report-a-notifiable-disease) to report any other suspected infectious disease if you think it may present a significant risk to human health. Select the category ‘other significant disease’.

Reporting other public health hazards

To report other public health hazards to UKHSA, such as chemical or radiation exposure, contact your local UKHSA health protection team (https://www.gov.uk/health-protection-team).

Reporting organisms that cause infectious diseases

Diagnostic laboratories must report notifiable organisms (https://www.gov.uk/guidance/notifiable-organisms-and-how-to-report-them) that are causative agents of infectious diseases to UKHSA.

Why you must report a notifiable disease

Reporting suspected cases of infectious disease to UKHSA protects public health.

Health protection teams use your information to manage outbreaks and prevent further infections. For example, they:
- provide public health advice to reduce the spread of infection
- carry out contact tracing
- send additional diagnostic test kits
- identify disease trends and risks
Your duty to report notifiable diseases is outlined in the Public Health (Control of Disease) Act 1984 (http://www.legislation.gov.uk/ukpga/1984/22), the Health Protection (Notification) Regulations 2010 (https://www.legislation.gov.uk/uksi/2010/659/contents/made), and the Health Protection (Notification) Regulations 2025 (https://www.legislation.gov.uk/uksi/2025/291/made).

You can provide confidential patient information without consent under Regulation 3 of The Health Service (Control of Patient Information) Regulations 2002.
