Public health specialists in the Public Health Protection Unit (PHPU) are responsible for dealing with outbreaks of infectious diseases and environmental incidents that may harm health.

For example, we work to prevent people from developing infections by measures such as improving immunisation coverage and contact tracing (finding out who has been in contact with the infected person) when there is a case of TB or meningococcal meningitis.
We also work closely with community health staff such as GPs and hospital colleagues as well as staff from other organisations, including your local council, to investigate the cause of the outbreak or incident and put measures in place to control it.

This means that where there's an outbreak of an illness such as E Coli or an environmental incident such as diesel spill into water, we're on the case.
