Mpox (previously known as Monkeypox)

Please click the frequently asked questions below for further information and IPC precautions required:

• What is Mpox?

  Mpox (previously known as monkeypox) is a rare disease caused by infection with the mpox virus. Mpox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. Mpox symptoms are similar to smallpox symptoms, but milder, and mpox is rarely fatal. Mpox is not related to chickenpox.

  Mpox was first discovered in 1958 when outbreaks of pox like disease occurred in monkeys kept for research. The first human case was recorded in 1970 on the Democratic Republic of Congo (DRC). Since then it has been occurred in several African countries, before 2022 most cases were reported in DRC and Nigeria.

  There are 2 main genetic groups of Mpox known as clades. In 2022 cases of human Mpox were reported in multiple counties including the UK and Ireland. This is was associated with sexual activity and was caused by Mpox Clade II. Clade II is no longer considered a High Consequence Infectious Disease (HCID) in the UK.

  

• How does it spread?

  Mpox can spread to anyone through close, personal, often skin-to-skin contact, including:

  • Direct contact with mpox rash and scabs from a person with mpox, as well as contact with their saliva, upper respiratory secretions, and areas around the anus, rectum, or vagina

  This direct contact can happen during intimate contact, including:

  • Oral, anal, or vaginal sex, or touching the genitals (penis, testicles, labia, and vagina) or anus of a person with mpox
  • Hugging, massage, and kissing
  • Prolonged face-to-face contact
  • The risk is considered low for getting mpox by touching objects, fabrics, and surfaces that have been used by someone with mpox and not disinfected, such as clothing, bedding, towels, fetish gear, or sex toys.

  Other points to remember:

  • Incubation period is between 5 and 21 days
  • It is usually a self-limiting illness, where people recover within several weeks. However, some can develop severe illness.
  • People are considered infectious from onset of symptoms until scabs have fallen off and there is intact skin underneath.
• What are the symptoms of Mpox?

  

  People with mpox often get a rash that may be located on hands, feet, chest, face, or mouth or near the genitals, including penis, testicles, labia, and vagina, and anus.

  • The rash will go through several stages, including scabs, before healing.
  • The rash can initially look like pimples or blisters and may be painful or itchy.

   

  Other symptoms of mpox can include:

  • Fever
  • Chills
  • Swollen lymph nodes
  • Exhaustion
  • Muscle aches and backache
  • Headache
  • Respiratory symptoms (e.g., sore throat, nasal congestion, or cough)

   

  You may experience all or only a few symptoms

  • Sometimes, people have flu-like symptoms before the rash.
  • Some people get a rash first, followed by other symptoms.
  • Others only experience a rash.

  

• Why is this important?

  If NIAS staff are aware that the patient has a suspected or confirmed Mpox this should be communicated to EAC / NEAC and the receiving unit when transferring the patient to ensure effective patient care and management.

  This should also be communicated to the IPC team in hours or when next available.

• IPC Precautions
  • Airborne Precautions
  • A fit tested FFP3 mask – Ensure a fit check is completed
  • A Fluid resistant Coverall
  • Full face visor
  • Gloves
  • Apron

   

  Conveyance:

  When the patient is on a vehicle ensure that –

  • the ventilation systems are operational
  • the bulkhead is closed
  • on arrival at a receiving unit ensure that you inform the staff you have arrived before entering
  • if the patient can tolerate it ask them to wear a fluid resistant surgical mask
• What cleaning is required?
  • All equipment and the ambulance should have a deep clean with a hypochlorite solution.
  • Open all doors to allow the vehicle to be ventilated before and during cleaning.
  • Waste can be treated as healthcare (clinical) category B waste. It can be disposed of in an orange bag for alternative treatment and does not have to be sent for incineration. The waste is assigned to UN 3291, clinical waste.
  • Linen must be bagged in an alginate bag and sealed, then placed into a red linen bag and secured prior to placement with the soiled linen. If the patient is transported to hospital, the waste should be left with the receiving unit.
• Do staff need prophylaxis or follow up?

  A list of staff will be recorded of all staff who have had interaction with the suspected/confirmed case.

  All staff in contact with a case of Mpox will be individually risk assessed by the multi-agency team.

  If you believe you have had a breach in PPE, ensure line manager and OH are informed immediately.
