There have been 34 cases of monkeypox identified in NSW since 20 May 2022.

The situation with monkeypox in NSW is changing rapidly. Many of the cases are in men who have sex with men and have been acquired overseas, but some cases in NSW are likely to have been acquired in Australia.

Monkeypox spreads through close skin-to-skin physical contact with someone who has symptoms, such as when you are having sex, or by direct contact with contaminated objects, such as bedding, towels or clothes.

Symptoms include:

  • rashes, lesions or sores, particularly in areas that are hard to see such as the genitals, anus or buttocks and on the face, arms and legs
  • ulcers, lesions or sores in the mouth
  • fever, headache, muscle aches, backache, swollen lymph nodes, chills and/or exhaustion prior to the rash or lesions developing.

If you have symptoms, self-isolate and seek medical attention immediately. Call your GP, local sexual health clinic or the NSW Sexual Health Infolink on 1800 451 624. It is best to call and not attend a health service in person. If you need to attend in person, wear a mask.

Call Triple Zero (000) immediately if your symptoms are severe and tell them you may have monkeypox.

What is monkeypox (MPXV)?

Monkeypox is a viral infection that causes a rash. It is spread by skin-to-skin contact with someone who has monkeypox. Most people recover within a few weeks.

Since May 2022, there has been a global increase in monkeypox cases reported from multiple countries where monkeypox is not usually seen. Most of the cases are in men who have sex with men.

The situation with monkeypox in NSW is changing rapidly. While most cases have been acquired overseas, a small number may have acquired their infections in Australia.

What are the symptoms?

Symptoms usually begin 7-14 days after exposure. This can be as short as a few days or as long as 21 days.

Monkeypox symptoms may include:

  • rashes, pimple-like lesions or sores, particularly in areas that are hard to see such as the genitals, anus or buttocks. and on the face, arms and legs.
  • ulcers, lesions or sores in the mouth
  • People can experience fever, headache, muscle aches, backache, swollen lymph nodes, chills and/or exhaustion prior to the rash or lesions developing

The lesions start as a flat red rash that develops into pustules, which then form crusts or scabs and fall off.

How does monkeypox spread?

Monkeypox mainly spreads from one person to another by direct skin-to-skin contact. It may be spread by breathing in droplets breathed out by someone who has monkeypox during prolonged close contact, but this is rare. It can also be spread through contact with infected bodily fluids or contaminated objects, such as bedding or clothes.

Monkeypox may be passed on during sex. It is not known how long the monkeypox virus remains present in semen and other genital excretions. People who have monkeypox should abstain from sex for the duration of their infection. People who have recovered from monkeypox should use condoms when engaging in sexual activity for 8 weeks after recovery.

People with monkeypox are infectious from the time they first get symptoms until all the lesions have crusted, the scabs have fallen off and a fresh layer of skin has formed underneath.

Who is at risk of monkeypox?

Most people are not at risk of monkeypox.

People at highest risk are men who have sex with men, particularly those who are travelling to outbreak areas, have multiple sexual partners or attend large parties or sex on premises venues.

To date most people with monkeypox in Australia have been infected while overseas. However, some people have been infected in Australia following contact with people who have recently travelled overseas.

How is monkeypox prevented?

Staying alert for symptoms and taking steps to prevent infection

Vaccination is only one way to prevent monkeypox infection.

As there is still a risk of infection following vaccination, it's still important to take steps to reduce the chance of catching or spreading monkeypox.

  • Prevent the spread of monkeypox
    • Avoid close contact with people who have monkeypox.
    • Events such as parties or clubs where there is less clothing worn, and therefore a higher likelihood of direct skin-to-skin contact, carry risk of monkeypox exposure. Avoid any rashes or sores you see on others and minimise skin-to-skin contact.
    • Exchange contact information with your sexual partners to assist with contact tracing if needed.
    • Avoid contact with any materials, such as bedding or towels, that may have been in contact with an infected person.
    • Practise good hand hygiene. Wash your hands with soap and water or use an alcohol-based hand sanitiser.
  • Monitor for symptoms
    • Men who have sex with men who are returning from known outbreak hotspots such as Europe and North America should monitor for signs or symptoms of monkeypox, particularly those who have attended dance parties, sex parties, saunas, or sex on premises venues.
    • Check yourself for symptoms before you leave home. If you feel unwell or sick, or have any rashes or sores, do not attend events or venues.
    • If signs or symptoms develop, self-isolate immediately and seek care by calling ahead to make an appointment with your local GP or sexual health clinic.
    • Limit sexual partners for three weeks following your return from overseas.
  • Take action if you are exposed
    • If you are advised that you are a close contact of someone with confirmed monkeypox, self-isolate immediately and call your GP or sexual health clinic. If you have questions about monkeypox, contact the NSW Sexual Health Infolink on 1800 451 624.
    • If you are caring for someone with monkeypox, use personal protective equipment (PPE), including gloves and a N95 mask.
    • Use a condom during sex for at least 8 weeks after you recover from monkeypox.

Vaccination

Smallpox vaccines can provide protection against monkeypox because the two viruses are closely related. NSW Health has secured limited supplies of a new vaccine against smallpox (JYNNEOS) which has fewer side effects than previous smallpox vaccines and can be safely used by all groups of people, including those who are immunocompromised.

NSW Health will begin vaccinating people at highest risk from monkeypox from 8 August 2022.

Doctors and other community partners are identifying people who are most at risk from monkeypox to receive a vaccine when the first supplies of vaccine become available. Many people will not be eligible during the initial rollout. NSW Health is working to ensure the most vulnerable people access the vaccine first.

NSW Health expects to receive a further 30,000 doses at the end of September and 70,000 doses in early 2023.

NSW Health will provide more information about eligibility and access to the vaccine at that time.

How is monkeypox diagnosed?

Diagnosis depends on the doctor suspecting monkeypox in someone who has monkeypox symptoms. Infection can be confirmed by testing the blister fluid or scabs from the skin rash.

How is monkeypox treated?

The illness typically lasts for 2−4 weeks and is mild. Most people with monkeypox only need regular over-the-counter pain medicines and oral fluids and can be monitored by their GP or treating clinician. A few people may need supportive management such as intravenous fluids and treatment to control fever or pain.

There are antiviral medications available that may help to treat people with severe illness.

What is the public health response?

Doctors, hospitals and laboratories must notify any suspected cases to the local public health unit immediately. Public health unit staff will initiate a public health investigation, contact tracing and control measures.

Further information

If you think you might have symptoms of monkeypox, please call ahead to your GP or local sexual health clinic. Wear a mask when attending the clinic.
