Influenza and respiratory syncytial virus (RSV) healthcare data paused

We will not be updating influenza and RSV healthcare data for the next few months. This is because the systems used to report this data do not operate during the summer. We hope to resume updating this data in the autumn.

Weather health alerts

The alerting system provides an early warning when adverse temperatures are likely to impact on the health and wellbeing of the population.

The Weather health alerting system is provided by the UK Health Security Agency (UKHSA) in partnership with the Met Office. It's intended to provide early warning to the health and social care sector, the responder community, the voluntary and community sector and government departments when adverse temperatures are likely to impact on the health and wellbeing of the population. The Weather health alerting system is made up of the Heat-Health Alerts (HHA) and Cold-Health Alerts (CHA). The Weather health alerting system underpins the Adverse Weather and Health Plan.

The core alerting season for the HHA runs from 1 June to 30 September, with the core alerting season for CHA running from 1 November to 31 March. Should a period of heat or cold occur that meets alerting criteria outside of the core alerting periods, an extraordinary alert will be issued.
