The emergence of a new mpox variant has been confirmed in Toronto. Toronto Public Health (TPH) reported two travel-related cases of the rapidly spreading clade Ib strain. This marks the first identification of this variant in both Toronto and Ontario. The variant has been linked to outbreaks in Central and Eastern Africa and has been detected in limited travel-related cases internationally, notably in several European nations.
Details on the New Mpox Variant
Since 2022, Toronto has only reported the clade IIb strain cases of mpox. However, the Public Health Agency of Canada noted that the new mpox variant is considered “less severe” than the clade Ia strain. TPH has observed a higher concentration of mpox cases among residents in downtown Toronto, and in 2022, there were 155 confirmed cases in the city.
Understanding Mpox
Mpox is a viral illness that spreads primarily through person-to-person contact. The transmission can occur through:
- Infected lesions
- Skin blisters
- Body fluids
- Respiratory secretions
- Contaminated materials such as clothing or bedding
- Bites or scratches from infected animals
The virus is predominantly spread through intimate contact, affecting gay, bisexual, and other men who have sex with men more significantly.
Symptoms and Prevention
Both variants of the mpox virus share similar symptoms, including:
- Painful skin lesions
- Fever
- Flu-like symptoms
Vaccination is the most effective method for preventing mpox transmission. TPH provides the Imvamune vaccine at no cost through various clinics and community partners, and no OHIP card is required. To achieve optimal protection against both mpox strains, two doses are recommended. Individuals previously receiving one dose are encouraged to obtain a second dose 28 days after the first. Those who have received two doses do not need additional vaccinations.
Availability of Vaccination
Appointments for vaccination can be scheduled online or through local 2SLGBTQ+ health-care providers. Even those who have had the smallpox vaccine are advised to get vaccinated against mpox, as previous vaccinations may not provide sufficient protection. Additionally, post-exposure treatments are available for individuals who believe they may have been exposed to the virus.
As mpox cases evolve, public awareness and preventive measures remain crucial to curbing its spread in Toronto and beyond.
