Infection service

Treating patients with all types of suspected or proven infections

The infection service at the Guy’s and St Thomas’ provides specialist inpatient and outpatient infection services for clinical diagnosis and management of adult patients (16 years or older). We treat all types of suspected or proven infections and/or infection control related problems excluding HIV services, which are provided by the Harrison Wing team.

The medical team consists of consultants with expertise in clinical infectious diseases, medical microbiology, infection control, virology and general medicine with supporting specialist registrars, a core medical trainee and a foundation year trainee.

We work closely with other departments across Guy’s and St Thomas’ Hospitals and Evelina London Children’s Hospital to provide a comprehensive infection service to all patients with infections related to other medical conditions.

The team has considerable experience in caring for patients with:

  • infections acquired in the UK 
  • illnesses acquired overseas and in the tropics 
  • healthcare associated infections
  • exposure to animal bites
  • arthropod borne infectious diseases
  • viral illnesses 
  • bacterial illnesses 
  • viral hepatitis 
  • fevers of unknown origin 
  • bone and joint infection
  • vascular graft infection
  • infections in the immunocompromised.

Outpatient parenteral antibiotic therapy (OPAT) service

We offer an outpatient parenteral antibiotic therapy (OPAT) service (PDF 108Kb) that supports patients in the community who are receiving intravenous anti-microbial therapy. The OPAT service primarily facilitates early discharge from Guy's and St Thomas’ Hospitals for patients whose only barrier to discharge is the requirement for intravenous therapy. We also work closely with the Guy's and St Thomas' @home services in Lambeth and Southwark.


Our Centre for Clinical Infection and Diagnostics Research is a research facility set up as a joint initiative by Guy's and St Thomas' NHS Foundation Trust and King's College London.

We conduct research that improves the prevention, diagnosis and treatment of infectious diseases relevant to our local population and beyond. Find out more about our projects.
