Infection service

Treating patients with all types of suspected or proven infections

Coronavirus: Infection service update

Due to increased demand on the hospital due to the COVID-19 pandemic we are having to make significant changes to our services which may require cancellation of appointments. 


We are attempting to contact all patients with a future scheduled appointment.

  • In some cases we are changing appointments to a telephone consultation, and in certain circumstances, a video appointment.

  • Some appointments may be cancelled without a future date being arranged at this stage. If we cancel your appointment you will remain on our waiting list and we will contact you in due course.

  • Some patients may be discharged back to their GP and we will write to you if this is the case.

If you have not heard from us within three days of your scheduled appointment please contact us by emailing If you are unable to use email or your query is urgent, please call 020 7188 3148. Our phone lines are very busy and there may be a wait for your call to be answered.

If you are an existing patient who has previously been seen in our service and need advice from the clinical team please see below for the appropriate option. Please state your name, hospital number, treating clinician's name, question and urgency of your query. 

We will endeavour to get back to you within two working days or sooner for very urgent issues.

Contact us by email or telephone for: 

  • any queries regarding your appointment or the contact details

  • a request for clinical advice if you are already a patient known to our service (if possible please have to hand your hospital number and name of your treating consultant)

Advice and guidance

We are doing everything we can to support GPs and your patients during the COVID-19 pandemic. Therefore, prior to any referral, we would strongly advise that GPs seek advice and guidance via e-RS or Consultant Connect (if it is available in your area). Please note that all of our services available on e-RS are set up for advice requests. This will enable the clinical team to review your request and provide an interim treatment plan for ongoing management of a patient.  They can also advise or provide clarification regarding a patients test results.

The GP can attach documents to the e-RS advice request, which may include diagnostic results, scanned images (e.g. ECGs). Providers can also respond with attachments.

There is always a consultant microbiologist and consultant virologist on call 24/7 for urgent clinical queries. They are contactable via the hospital switchboard on 020 7188 7188. 

eRS referrals

If you feel that a referral is absolutely necessary, please refer via eRS and use the 'defer to provider' functionality for urgent/two week wait referrals.  Please attach the referral letter at the point of referral or within 24 hours. For two week wait referrals, please ensure that the patient meets the criteria ahead of referring. Please do not refer urgent patients under two week waits as this will overwhelm the service.

The Trust will vet the referral and either book into a virtual appointment or add the patient to the waiting list if they need a face-to-face appointment. In some cases the referral may be returned (rejected) back to you with advice.

Please do not defer to provider routine referrals. Send the appointment request to the patient so they can do this when they are ready to book.

Please consider this before making any referral as our capacity to see new patients is very limited.

For any training issues or technical assistance with eRS/Smartcards, please contact your local commissioning support unit facilitators or the Registration Authority Helpdesk.

Consultant Connect

For SEL GPs, your CCG has commissioned the Consultant Connect service so you can also use this to seek advice. We are in the process of expanding our Consultant Connect lines – these will be available Monday to Friday, 9am-5pm, and the communication will come via your local CCG bulletins so please ensure you cascade this within the practice.

Please see the frequently asked questions we are receiving from our patients.

Service overview 

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.
