INTRODUCTION
This policy has been developed for use in NHS Lanarkshire as part of the Control of
Infection policy manual. This policy should be read in conjunction with the following policy:
 Section 1 – Standard Infection Control Precautions
2.
AIM, PURPOSE & OUTCOME
To ensure that healthcare workers (HCWs) consider Viral Haemorrhagic Fever (VHF) as a
possible diagnosis in patients with an indicative history and symptoms.
To ensure that all HCWs take appropriate actions to minimise the risk of cross infection to
themselves and others by urgent and appropriate referral in line with the guidance
developed by the Department of Health.
To ensure that all HCWs apply appropriate infection prevention and control precautions
when providing care for patients with suspected or known infection with VHF.
3. 1
SCOPE
This policy is designed to safeguard patients, staff and the wider public from the risk of
VHF.

4.1
VIRAL HAEMORRHAGIC FEVERS
Viral Haemorrhagic fevers (VHF) are severe and life threatening diseases caused by a
range of viruses. They are endemic in some parts of the world, particularly:
 Africa
 South America
 Middle East, and
 Eastern Europe.
VHFs are of particular public health importance because:
 they can spread within a hospital setting
 they have a high case-fatality rate
 they are difficult to recognise and detect rapidly, and
 there is no effective treatment.

Version No.2.3
Of 15 viral agents, 4 are more commonly known:
 Ebola (Filoviridae)
 Lassa (Arenaviridae)
 Crimean/Congo haemorrhagic fever caused by Nairovirus
(Bunyaviridae) and
 Marburg
Fever, headache, myalgia, pharyngitis, diarrhoea, vomiting,
macropapular rash, bruising, bleeding, multi organ failure
Up to 21 days (dependent on virus)
Can be up to 61 days post onset
Experimental evidence suggests that the virus can survive on
surfaces in lower temperatures for over three weeks
People remain infectious as long as their blood and body
fluids, including semen and breast milk, contain the virus e.g.
for up to 7 weeks after recovery from illness
Direct contact (through broken skin or mucous membrane)
with blood or body fluids, and
Indirect contact with environments contaminated with
splashes or droplets of blood or body fluids
There is no evidence of an aerosol transmission risk from
VHF patients
Exposure to patients prior to the onset of fever does not
appear to carry the risk of transmission
Bite of an infected tick or mosquito
Animal/insect hosts
No natural environmental reservoirs in UK
Secondary infection risk from exposure to infected blood or
body fluid
Travellers, healthcare workers, laboratory staff
All recorded cases of VHF in the UK have been acquired
abroad, with the exception of one laboratory worker who
sustained a needle-stick injury.
Yes

4.2
PATIENT RISK ASSESSMENT
A risk assessment of exposure to biological agents is a legal obligation under the Control
of Substances Hazardous to Health (CoSHH) Regulations.
It is the responsibility of the general practitioner, or admitting physician to recognise the
risk of VHF.
VHF infection is possible in any patient presenting with:
 a fever of unknown origin, or a history of fever within previous 24 hours, AND
 a travel history or epidemiological exposure within 21 days
Other symptoms of concern would be:
 bruising or bleeding,
 uncontrolled diarrhoea or vomiting.
When assessing a patient with fever who has a history suggestive of VHF, it is difficult to
make a firm diagnosis solely on clinical grounds, therefore attention must be paid to
epidemiological evidence e.g. travel to endemic areas, association with any known cases.
A possible VHF case must fulfil the following conditions:
A) The patient has a fever or history of fever in past 24 hours AND has returned from a
VHF affected area or endemic country within 21 days
OR
B) The patient has a fever or history of fever in past 24 hours AND has cared for / come
into contact with body fluids of / handled clinical specimens (blood, urine, faeces, tissues,
laboratory cultures) from an individual or laboratory animal known or strongly suspected to
have VHF?
If any of the above conditions are fulfilled secure answers to the following questions:
1) Patient travelled to Guinea, Liberia, Sierra Leone, Mali, Congo DR or other countries
where cases of Ebola / VHF have been reported during past 21 days?
2) Lived or worked in basic rural conditions?
3) Visited caves OR mines, or had contact with or eaten primates, antelopes or bats?
4) Sustained a tick bite, crushed a tick OR had close involvement with animal slaughter?
If none of the four above apply AND the patient has no history of bruising, active bleeding,
vomiting or diarrhoea, then there is a LOW POSSIBILITY OF VHF.
To assist clinical decision making, please see: APPENDIX 1 – VHF Risk Assessment
Algorithm
For up to date information on VHF risk maps see: Travax and WHO Ebola Response
Roadmap
Version No.2.3
December 2014
Page 6 of 35
Management of Viral Haemorrhagic Fevers
Following initial assessment, and where VHF is considered, formal risk assessment
MUST be carried out by the on-call Consultant Infectious Diseases (ID) physician
[Contact via Monklands General Hospital switchboard: Telephone 01236 748 748]
Following this assessment, patients will be classified as:
 Unlikely to have a VHF – answers no to questions A & B on page 6
N.B. With this classification, a patient is no longer suspected of having VHF, and as
such additional PPE and patient isolation are no longer required (unless they are
needed for other clinical reasons). There is also no need for a VHF laboratory
communication cascade or a teleconference with the Scottish Ambulance Service.
However, if the patient’s risk classification is ever upgraded to “Low Possibility” or
“High Possibility”, then the appropriate guidance as shown in this document should
be followed. An example where this may occur is when an individual is initially
asymptomatic after returning from a VHF endemic country, therefore is “unlikely to
have a VHF”, but subsequently becomes symptomatic.

Low Possibility – (1) answers yes to question A, but (2) answers no to question B
and all stated additional questions and (3) does not have extensive bruising or
active bleeding.

High possibility – (1) answers yes to question B, or (2) answers yes to question A
and any additional question (3) and/ or has extensive bruising or active bleeding.

Confirmed VHF – any patient with a positive VHF screen
A patient pathway is available as Appendix 2 to help determine the initial actions and
precautions required to safely manage patient care and minimise the risk of infection to
staff and the wider population. A sample contact tracing form is available as Appendix 9 to
record list of contacts that may have been inadvertently exposed to a high possibility case.
The Consultant Microbiologist will liaise with the Imported Fever Service at Public Health
England to discuss VHF screening as appropriate: Telephone 0844 7788990.
From 1st December 2014, a Scottish VHF testing service is available for testing samples
of “high possibility of VHF” using molecular (real time PCR) approaches. A checklist
summarising the actions for Consultant Microbiologists is available as Appendix 4.
4.2.1
MANAGEMENT OF PATIENT IN PRIMARY CARE
All suspected Ebola cases that present to primary care should be discussed with
the ID Consultant who will lead the risk assessment and arrange clinical review.
Individuals that telephone the surgery or walk-in centre and report that they are unwell and
have visited an affected area in the past 21 days must be told not to visit the surgery or
walk-in centre. The patient should be called back as soon as possible by the GP or duty
doctor to risk assess prior to discussion with the ID Consultant.
Version No.2.3
December 2014
Page 7 of 35
Management of Viral Haemorrhagic Fevers
Surgeries, out of hours’ centres and walk in centres should clearly display information requesting patients to tell the receptionist on arrival if they are unwell and have returned from
an Ebola-affected area within the last 21 days. Any patients identifying themselves to
reception staff should not sit in the general waiting room once Ebola is considered a
possibility. These patients should be isolated in a single side room immediately to limit
contact, and urgent clinical advice sought from the ID Consultant.
If at the time of a consultation it becomes apparent that Ebola may be a possibility then the
attending primary care clinician should take immediate steps to isolate the patient to limit
further contact and seek advice from the ID Consultant. Hand hygiene is an important
infection control measure; the Ebola virus is not a robust virus, and is readily inactivated,
for example, by soap and water or by alcohol. It is important to remember that
transmission of Ebola from person to person is only through direct contact with the blood
or body fluids of a symptomatic infected person.
There is no evidence of Ebola transmission through intact skin or through small droplet
spread, such as coughing or sneezing. Cleaning and decontamination of any rooms in
which a suspected or confirmed Ebola patient has been isolated or any facilities used by
the patient should be discussed with the local Health Protection Team.
Further information for GP practices can be found on the Health Protection Team Firstport
page.
4.3
PATIENT MANAGMENT – INFECTION PREVENTION AND CONTROL
It is assumed that ALL STAFF will observe standard infection control precautions (SICPs)
at ALL TIMES with ALL PATIENTS, to minimise the risk of infection to staff and other
patients.
In addition to standard precautions, staff should also be familiar with, and practice the
following Transmission Based Precautions (TBPs):
 Contact precautions
 Droplet precautions
 Airborne precautions
Personal Protective Equipment (PPE) must be worn by all staff caring for suspected VHF
patients.
This PPE must establish a barrier against contact with contaminated surfaces, splash,
spray, bulk fluids and aerosol particles. It must also cover all exposed skin with sufficient
integrity to prevent any ingress or seepage of liquids or airborne particles.
Please see Appendix 3 for detailed advice on the infection control precautions required.

SPECIMEN HANDLING & LABORATORY PROCEDURE
To minimise the risk of contamination to staff and patients, point of care/near patient
testing equipment (e.g. blood gas analysers) should not be used to process samples from
patients who are being assessed for VHF. The only exception to this is blood glucose
(capillary testing) testing for diabetics.
All samples should be sent to the appropriate laboratories for processing and the
laboratory staff advised, before sending samples, of a possible diagnosis of VHF. The
receiving laboratory should telephone the ward to confirm receipt of samples. Specimens
from patients who have a high possibility of confirmed VHF should only be requested
following discussion with the ID Consultant.
Routine biochemistry/haematology tests can be taken and sent (with prior notification) to
the laboratories whilst awaiting the outcome of the malaria film.

To minimise the risk to staff, the following must be observed:
 Laboratory staff MUST be informed of specimens BEFORE THEY ARE SENT
 Specimen handling and storage should be kept to a minimum
 Vacutainer system must be used
 All specimens from cases with a high possibility of VHF must be appropriately
labelled, double bagged and placed into a rigid PVC container (i.e. a bio bottle
within an appropriate cardboard box) ¹ (obtained from the laboratory) for transport
from the Emergency Department / ward to the laboratory
 Pneumatic tube system must not be used for the transport of samples to the
laboratory
 Strict adherence to standard infection control precautions and laboratory
procedures by all staff at all times.
 Clinical staff MUST inform the laboratory if the patient risk category changes during
the period of admission.
Specimen handling for VHF investigations
 Non essential samples (urine, stool and sputum) will only be processed after
discussion between Consultant Microbiologist and Infectious Diseases (ID)
Consultant.
 It has been agreed that patients with a high possibility of VHF should receive
unmatched Group O Rh (D) Negative red cells and Group AB FFP/CRYO without
any pre-transfusion serological testing if their clinical situation demands transfusion
support.
 Samples must be transported to the laboratory by clinical staff and handled
directly to the Microbiology BMS staff to the named person expecting the sample
 No samples should be left unattended in the Laboratory reception
 All samples must be processed in the Category 3 Containment Laboratory
 Laboratory forms must accompany the specimen to the category 3 laboratory. Data
entry into the Laboratory Information System must be performed in Category 3. No
forms should be scanned or leave the Category 3 facility
 Blood tubes or blood culture bottles that are visibly contaminated with blood or are
leaking will not be accepted and repeat samples will be required
 Visibly soiled forms should not be accepted and the ward should inform to provide a
repeat form asap
 Appropriate disinfection of sample containers should be performed prior to handling
the sample.
 Containers and left over sample must be disposed as hazardous waste and
incineration and autoclave. Samples should not be kept after processing
 Appropriate PPE must be used in accordance with the laboratory Standard
Operating Procedure.
Adherence to the NHSL Standard Operating Procedure (SOP): Guidelines for Processing
Samples Potentially Infected with Viral Haemorrhagic Fever is expected when handling

samples from these patients. Use of personal protective equipment (PPE) in accordance
with the SOP is required when processing specimens.
¹ Rigid PVC UN marked container which meets the standard required by The Carriage of Dangerous Goods and Use of
Transportable Pressure Equipment Regulations 2009
Appendix 5 provides a summary of the steps involved in taking blood samples from
patients with a possibility of VHF.
Retrieval of specimens
If the possibility of VHF is realised after specimens have been sent, it is the responsibility
of the Consultant Microbiologist to ensure that specimens are:
 Located quickly
 Made safe by autoclaving and incineration (Category A waste). OR
 If not for immediate disposal, packed in rigid containers, which should be surface
decontaminated and retained within the laboratory awaiting safe disposal
4.5 VHF LABORATORY COMMUNICATION CASCADE
The ID Consultant in charge of the patient will contact the Consultant Microbiologist to
inform of the possibility of VHF. The Consultant Microbiologist will cascade this information
to the relevant Consultant Biochemist and Haematologist to alert them.

4.6 PATIENT TRANSPORT
GPs should not use 999 ambulance services to arrange hospital transfer of patients from
the community. The Infectious Disease Consultant will arrange, with the SAS, for the
transfer of any patients who are suspected of being infected with VHF.
VHFs are classified as Ambulance Category 4 infectious diseases across all Ambulance
Services in the UK.
Version No.2.3
December 2014
Page 12 of 35
Management of Viral Haemorrhagic Fevers
Therefore, patients categorised as ‘low possibility’; ‘high possibility’ or ‘confirmed’ will
require to be transferred in accordance with Scottish Ambulance Service (SAS) protocols.
Only staff who have received specialist training are permitted to transport these cases.
Ambulance control will coordinate the Special Operations Response Team (SORT).
The decision to transfer a patient should be made by the Consultant in Infectious
Diseases. Transfer to any unit outwith NHS Lanarkshire (e.g. Royal Free Hospital London
High Level Isolation Unit (HLIU) will only be arranged following consultation and
agreement with referring clinician or clinicians at the HLIU/other unit to which the patient is
to be transferred.
Consultant ID
Call ambulance control - request ‘National Operations Manager’
Rapid teleconference - ID consultant/SAS/ referring doctor (+/CPHM - discuss patient risk category, medical and other
requirements
Special operations response team (SORT) team mobilised with 2 nd
team following as back up.
The ID Consultant is responsible for liaising with SAS to arrange emergency tertiary
referral to the Royal Free Hospital, London HLIU. If an isolator is required (for confirmed
cases) SAS SORT will liaise with North East Ambulance Service or London Ambulance
Service to coordinate the provision of this.
Transfer of a patient within the UK to an HLIU may be necessary when either:
 the patient has had a positive VHF screen result, OR
 the patient has been categorised as ‘high possibility of VHF’, AND
 has bruising or bleeding, OR
 uncontrolled diarrhoea or uncontrolled vomiting.
The Director of Public Health of the patient’s health board of residence and the Scottish
Government Health Department must be informed promptly of referral to the Royal Free
Hospital, London HLIU.
4.6.1
INTERNAL TRANSFER OF PATIENTS
Patients admitted via the Emergency Department may be required to be transferred
internally to Ward 2 (MGH) Infectious Diseases Unit following the NHS Lanarkshire
radiation procedure.

4.7 LAST OFFICES, POST MORTEM & GUIDANCE FOR FUNERAL STAFF
Post Mortem:
 A post mortem examination on a person known to have died of VHF exposes staff
to an unwarranted risk and should NOT be performed.
 Removal of pacemakers or implants should only be undertaken following discussion
and agreement with the CPHM
Body preparation/last offices:
 Hygienic preparation and embalming on a patient known to have died of VHF
exposes staff to an unwarranted risk and should NOT be performed.
 Viewing of the deceased should be avoided.
 Where the body of a confirmed or suspected VHF patient is not in an isolator, staff
wearing suitable PPE should place the body inside double-sealable leak-proof body
bag, with absorbent material between each bag. Absorbent material should be
placed between each bag, and the bag sealed and disinfected with 1000ppm
available chlorine or other appropriate disinfectant. The bag should be labelled as
high risk of infection
 The body bag should be placed in robust coffin with sealed joints.
 Post mortem examinations should not be performed
 Blood sampling can be undertaken by a competent person to confirm or exclude
VHF diagnosis
 An infection control notification sheet should be completed for the funeral director
(section O of CIM)
Specific guidance for undertakers
 The person in charge of the mortuary has a statutory duty to protect people coming
into contact with infected bodies, and family and funeral directors must be informed
of the infection risk.
 The body bag/coffin must not be opened except if authorised by the Consultant in
Public Health Medicine (CPHM), and then only by a person designated by them.
 Transportation of the body out of the country is not recommended. Following
cremation, ashes may be safely transported.
 In the unlikely event of a VHF infected body being embalmed abroad and
transported back to the UK, it would need to be contained within a sealed zinc lined
transport coffin in accordance with International Air Transport Association IATA
requirements.
Return of personal effects
Version No.2.3
December 2014
Page 14 of 35
Management of Viral Haemorrhagic Fevers
The family of the deceased should be consulted and, as far as is reasonably practicable,
their needs and wishes should be respected. In principle; clothing, personal effects and
valuables may be returned to relatives in accordance with normal health service procedure
following decontamination.
Items of clothing visibly contaminated should be safely disposed of. Other items of clothing
should be autoclaved prior to laundering. Wedding rings, jewellery and other physical
artefacts should either be autoclaved or decontaminated using a validated disinfectant.
With sensitivity and respect for the dignity of the bereaved, relatives should be alerted that
some clothing fabrics and materials from which personal effects are made (e.g. plastics)
may be adversely affected or even destroyed by autoclaving or disinfection (hypochlorite,
the disinfectant of choice is a powerful bleach). In such cases, with the agreement of
relatives, subsequent disposal may be the preferred option.
4.8 COMMUNICATION CASCADE
Any possible, highly possible or confirmed case of VHF must be notified to the Consultant
in Public Health Medicine (CPHM) without delay.
The On- Call CPHM will issue a communication cascade to relevant clinical and
management colleagues about a possible diagnosis of VHF.
If transfer of the patient is likely, early communication with Scottish Ambulance Service is
required. Following notification, a teleconference will be arranged to discuss the risk
assessment and clinical requirements for transfer.

4.10 PUBLIC HEALTH MANAGEMENT
On notification of any confirmed case of VHF, the duty Consultant in Public Health
Medicine will convene and chair an Incident Management team (IMT). An IMT may also be
considered for managing high possibility cases.
The CPHM or Director of Public Health must notify HPS and the Chief Medical Officer’s
team in the Scottish Government.
Using the Hospital Infection incident Assessment Tool (HIIAT) potential cases should be
categorised as:
 Low possibility of VHF- AMBER
 High possibility of VHF (with or without bleeding etc) –RED
 Confirmed case of VHF - RED
The ‘Management of Public Health Incidents Plan’ will be activated. Core membership of
the IMT will include:
 CPHM
 Health Protection Nurse
 Consultant in Infectious Diseases
 Consultant Microbiologist/Infection Control Doctor
 Scottish Ambulance Service
 Infection Control Nurse
 Consultant in Occupational Health Medicine
 Administrative support
 Communications officer
Other persons may be co-opted at the discretion of the IMT. Members of the IMT will be
responsible for briefing other members of their organisation as appropriate.

4.10.1 Management of Staff accidentally exposed to potentially infectious material
Any staff member who is exposed to, or sustains an injury with potential for exposure to,
blood or body fluids in high possibility or confirmed cases of VHF must:
 Take immediate first aid in line with current policy (e.g. needlestick injury)
 Wash the affected area soap and running water
 Irrigate mucous membranes with emergency wash bottles
All such exposures must be reported without delay to the Consultant in Infectious
Diseases, Infection Control Doctor and SALUS Occupational Health & Safety.
A DATIX form should be completed as per policy for any blood or body fluid exposure

12. Don a new (third pair) of gloves before handling the BioPack packaging and
packing the disinfected blood samples into it
13. Follow the instructions for the use of the BioPack.
14. Do not use pathology transport bag for the samples. Insert these tubes into the
bubble wrap provided in each pack labelled accordingly as biochemistry,
haematology and microbiology.
15. Place each of the blood culture bottles into a clear pathology transport bag and seal
the transport bags and place these samples into the BioJar
16. Screw the top onto the container.
17. Wipe down the outside of the container with alcohol wipes, Chlorox wipes, or a
chlorine based solution
18. Ask the designated person waiting outside the room with the transport box, to open
the door. Insert the jar into the box without touching the box.

Appendix 8: Health Facilities Scotland Waste Management Guidance for Highly
Infectious Waste to Accompany HPS Guidance
NHS Lanarkshire
1. The NHS Lanarkshire waste contractor should be notified that highly infectious waste is being
produced or may be produced from a suspected case. Notification can be made by the clinician or
via the Board’s NHS Waste Manager. Contact Harry Campbell NHS Lanarkshire Head of Technical
Services Tel: 01698 377697 Mobile: 07919 396816
2. ‘Soft’ waste should be double bagged in YELLOW clinical waste bags. Bags should then be
placed in a suitably sized rigid container for incineration (burn container). The container should
then be placed in a rigid 770 Ltr UN wheeled container.
3. Any sharps waste should be placed in a regular sharps container (the smallest size needed to
accommodate the amount of waste produced, ensuring the sharps box is not filled more than ¾
full). The container should then be sealed and placed in a suitably sized rigid container for
incineration (burn container). The container should then be placed in a rigid 770 Ltr UN wheeled
container.
4. The outer packaging of highly infectious waste containers must be clearly labelled, the label
must state:
• Waste description: ‘highly infectious waste’;
• The source or point of generation of the waste: ‘room x / ward x’; and
• The date produced.
In the absence of pre-printed labels this information should be handwritten on the external
container.
5. The Contractor should liaise with the site regarding suitable short-term on-site quarantine
storage for highly infectious wastes separate from ALL other wastes. If a quarantine area is not
immediately available waste should be stored in the patient’s room in a safe manner e.g. bagged
and boxed. Quarantine areas for highly infectious waste should be away from areas used to store
other wastes, including other clinical wastes. Where practicable within the quarantine area boxes
containing highly infectious waste should be placed directly into a dedicated 770 litre wheeled
container to avoid double handling of the waste before uplift. Quarantine areas should be locked
to prevent unauthorised access and a record of all waste entering and leaving the area should be
maintained.
6. The timing and frequency of collection must be agreed with the waste contractor at a local level.
Highly infectious waste should not be permitted to accumulate.
7. The contractor is responsible for providing any additional packaging or labelling required prior to
movement off site.
8. The Board will work with the contractor in order to obtain the DfT derogation required to move
this waste in line with the Carriage Regulations 1996 (as amended).
9. In the event that this procedure requires to be activated any associated costs will appear in the
regular monthly invoice, thus no further authorisation should be required from the Board Waste
Management Officer.
