Imported fever service (IFS)

The imported fever service (IFS) provides:

  • 24-hour, 7-day a week telephone access to expert clinical and microbiological advice to support management of febrile patients, infection control and public health interventions
  • 24 hour on-call molecular diagnostic service for viral haemorrhagic fevers and certain key differential diagnoses eg malaria, dengue
  • next working day diagnostic service for a range of other acute imported fevers such as chikungunya and rickettsias
  • panels of diagnostic tests designed for 10 world regions, with the aim of delivering a positive diagnosis rather than ruling out single infections

Expert advice is provided by PHE consultant microbiologists and virologists and by infectious disease physicians from PHE and our NHS partner organisations.
