Key messages
- There has been an increase in mpox cases notified in Victoria, with 8 cases reported from mid July 2025, including 5 cases locally acquired in metropolitan Melbourne.
- Mpox mostly impacts gay, bisexual, and other men who have sex with men (GBMSM), although anyone can be affected.
- All sexually active people with compatible symptoms should be tested, regardless of sexual orientation, vaccination status or travel history.
- Clinicians should remain aware of the possibility of mpox infection amongst other groups.
- Mpox testing can be done in any primary care service (general practitioner) or sexual health clinic.
- Vaccination should be promoted to all eligible people at risk of mpox, including second doses.
- Free mpox vaccine is widely available for eligible people through sexual health clinics, hospitals, general practitioners, Aboriginal health services, councils and pharmacies.
What is the issue?
There has been an increase in mpox cases notified in Victoria, with 8 cases reported from mid July 2025, including 5 cases locally acquired in metropolitan Melbourne.
This follows a period of reduced mpox activity with only 3 cases, and no local transmission reported between May and July 2025.
In addition, there is an ongoing risk of mpox being imported into Victoria by travellers returning from overseas or interstate.
In Victoria, mpox mostly affects gay, bisexual, and other men who have sex with men (GBMSM), however, it can affect anyone.
To help prevent further transmission in Victoria, clinicians are requested to increase testing for mpox and promote vaccination in at-risk groups.
For further information on mpox, see the Department of Health page on .
Who is at risk?
In Victoria at present, GBMSM (including those who identify as heterosexual) and their sexual partners are most at risk. Venues or events where close intimate or sexual contact occurs carry a higher risk of mpox transmission, particularly where casual or group sex occurs.
However, anyone can become infected, and anyone who has been in close and usually prolonged intimate contact with someone with mpox is at risk. While vaccination decreases the risk of mpox, those who are vaccinated, particularly if not fully vaccinated, may still become infected.
Symptoms and transmission
Symptoms may include lesions or rashes anywhere on the body, including the anogenital area. Other symptoms may include pain on urination (urethritis) or rectal pain, bloody stools and/or diarrhoea (proctitis). General symptoms include fever, chills, tiredness, headache, sore throat, muscle aches and swollen lymph nodes. Most people experience mild illness and recover within a few weeks, but severe illness can occur.
Mpox can spread from person-to-person through close (skin-to-skin) or prolonged contact, for example during sexual contact, as well as contact with contaminated items or surfaces, and respiratory droplets. Symptoms can occur up to 21 days after being exposed to mpox.
Recommendations
For GPs and other clinicians
Who to test:
- Test all sexually active people with compatible symptoms, regardless of sexual orientation, vaccination status or travel history. If testing for herpes simplex virus, test for mpox.
- Remain aware of the possibility of mpox infection in any patient.
- Be alert to the possibility of atypical and attenuated presentations in people who are fully and partially vaccinated. Some patients have had multiple presentations to healthcare prior to diagnosis.
How to test:
- Most testing occurs in primary care settings and can be easily and safely done. The risk to healthcare workers is very low and can be further reduced with use of appropriate personal protective equipment (PPE). This includes gloves, eye protection, gown and surgical mask. See the Public Health Laboratory Network (PHLN) for further advice on PPE.
- Request mpox PCR on suitable swabs (e.g. rash/lesion, anorectal, pharyngeal) and send to VIDRL via your routine pathology provider. See the PHLN for further advice on testing.
Advice and notification:
- Advise patients to cover lesions and abstain from sexual activity while awaiting the result. Advise to wear a mask if oral, throat or respiratory symptoms.
- See Better Health for recommendations to patients who are tested for mpox. If positive, the Local Public Health Unit will provide further advice.
- Any suspected or confirmed mpox cases should be urgently notified to the Local Public Health Unit by calling 1300 651 160.
- If mpox is suspected in a returned traveller or someone who has had contact with a returned traveller from affected countries in Africa, contact your Local Public Health Unit for advice.
Vaccinate:
- Offer free JYNNEOS® vaccine to all eligible GBMSM, their sexual partners and sex workers. Refer to the Better Health Channel mpox immunisation for eligibility.
- Check that eligible patients have had two doses of vaccine. Give the second dose if it is due.
- If your clinic does not offer vaccination, refer patients to the Mpox immunisation providers to find a provider.

For people at increased risk of mpox
- Take measures to protect yourself and others. Avoid sexual activity if you have any symptoms of mpox, consider limiting sexual partners, and keep contact details of new partners.
- Mpox vaccine is free for eligible groups. Two doses of mpox are required for optimal protection. If you haven’t had your second dose, get it now. See Mpox immunisation providers to find a provider of mpox vaccine.
- If you develop symptoms, restrict contact with others and get tested at your GP or sexual health clinic. Make sure to wear a mask, cover any exposed lesions and call ahead.
