What is monkeypox?

Monkeypox is a virus that can cause a rash, lesions or blisters. Before developing a rash, there is normally a period of fever, muscle aches and pains, and fatigue. Both animals and humans can contract the monkeypox virus, and it is spread by prolonged, close contact. 

Prior to 2022, most cases of monkeypox were located in central and western Africa, and cases outside of these areas were very rare.

Is monkeypox in Canada?

There were currently 957 cases of monkeypox in Canada as of August 10th, 2022

For a more up-to-date count of reported monkeypox cases, we recommend you check out the Canadian government's official website.

What are the symptoms of monkeypox?

Symptoms will often show after about 6-13 days of exposure but can take up to 21 days to appear.

These symptoms can include:

- Fever and chills

- Swollen lymph nodes

- Muscle aches and pains

- Headaches

- Exhaustion

- Rash or what appear to be blisters in your mouth, palms of the hands, soles of the feet, facial, genital area and/or in and around your butt

These symptoms can last from 2 to 4 weeks and will resolve on their own over time.

What does the monkeypox rash look like?

Monkeypox lesions can be flat or slightly raised and filled with clear or yellow fluid. They often will crust, dry up and fall off. Some people have very few lesions, while others may have thousands. 

The monkeypox rash is typically located on the face, palms of the hands and soles of the feet. The recent outbreak of cases in Europe and North America has included cases with lesions limited to the mouth, eyes and/or genital area. 

Can you die from monkeypox?

While severe cases can occur, this is very rare. 

Recent fatality rates have been around 1-5%, and the strain detected in Europe and North America in 2022 is milder, with no deaths recorded (as of June 10, 2022).

Who is most at risk for monkeypox?

It is important to remember that anyone can contract the monkeypox virus, regardless of their gender, sexuality or sexual behaviour.

However, there are a number of factors that can increase risk:

- multiple sexual partners

- living in the same household as a person who has monkeypox

- providing care for a person who has monkeypox

- being immunocompromised 

How does monkeypox spread from person to person?

The monkeypox virus can be transmitted from person to person through contact with an infected person’s:

- lesions/sores

- blood

- body fluids (including respiratory droplets)

- mucosal surfaces (eyes, mouth, throat, rectal area)

- contaminated clothing or linens (bedding and towels)

Are gay, bisexual and other men who have sex with men (gbMSM) at a higher risk of getting monkeypox?

Currently, we are seeing a number of cases in the gbMSM community. This may be because gbMSM are a social network that have close contact with each other. Another possibility is that gbMSM are more proactive about their health and undergo STI testing on a more frequent basis.

The risk of monkeypox is not limited to gay, bisexual and men who have sex with men (gbMSM). Anyone in close contact with an infectious person is at risk regardless of their sexuality. 

The World Health Organization has stated, “One reason we are currently hearing reports of cases of monkeypox from sexual health clinics in communities of men who have sex with men in this outbreak may be because of positive health seeking behaviour in this demographic.”

Monkeypox can resemble the rashes and lesions that are sometimes seen with other sexually transmitted diseases, which is a reason why these cases are being seen at sexual health clinics.

How do you test for monkeypox?

Several testing methods can be used for monkeypox, depending on the stage of the virus.

These tests can include:

- Blood tests 

- Swabs of lesion fluid, scab or crusts

- Nasopharyngeal/throat swabs 

If you have symptoms

If you have symptoms, it is suggested that you self-isolate and contact your healthcare provider. Your healthcare provider can guide you on testing and supportive care. 

Is there a monkeypox vaccine?

The smallpox vaccine called Imvamune is being used to vaccinate against monkeypox.

Imvamune is at least 85% effective in preventing monkeypox, and its safety has been evaluated in 20 completed clinical trials, where approximately 13,700 vaccines were administered to 7,414 people.  

Imvamune is administered subcutaneously (into a fatty part of the body) and is divided into two doses given 28 days apart.

The most common side effects seen with Imvamune include:

- discomfort at the injection site

- fatigue

- headache

- muscle pains

- nausea 

The smallpox vaccine is safe to receive if you have received your COVID-19 vaccine.

Where can I get vaccinated for Monkeypox?

Vaccine responses to monkeypox are managed by Public Health units.

Please note that there are certain criteria for receiving the vaccine and the Ministry of Health determines these.

The below resources can offer more information on upcoming vaccination sites.


British Columbia





If you are outside of these areas, please check your local public health unit for more information about vaccination efforts.
