Background

Mpox is a zoonotic disease, meaning it can be transmitted from animals to humans. It is caused by the monkeypox virus, which is a member of the Orthopoxvirus genus. The disease is similar to smallpox, but generally less severe. Mpox is endemic in certain parts of Africa, but outbreaks have occurred in other regions, including North America.

Outbreak Timeline

The first cases of the 2022–2023 mpox outbreak in Canada were reported in May 2022. The initial cases were linked to international travel and contact with infected individuals. The outbreak quickly spread, with cases reported in multiple provinces.

May 2022

In May 2022, the first cases were identified in Quebec, with subsequent cases reported in Ontario. Health authorities began contact tracing and public health measures to contain the spread.

June 2022

By June, the number of cases had increased significantly, prompting public health officials to issue warnings and guidelines to prevent further transmission. Vaccination campaigns were initiated, targeting high-risk groups.

July 2022

In July, the outbreak continued to grow, with cases reported in British Columbia and other provinces. Public health measures were intensified, including increased testing and vaccination efforts.

August 2022

The outbreak peaked in August, with the highest number of cases reported during this month. Public health campaigns focused on education and prevention, particularly among vulnerable populations.

September 2022 to 2023

From September 2022 onwards, the number of new cases began to decline, thanks to effective public health interventions and increased immunity in the population. By 2023, the outbreak was largely under control, with sporadic cases still being monitored.

Public Health Response

The Canadian public health response to the mpox outbreak involved several key strategies:

• Surveillance and Contact Tracing: Health authorities implemented robust surveillance systems to track the spread of the virus and identify new cases quickly.
• Vaccination Campaigns: Vaccines were distributed to high-risk populations, including healthcare workers and individuals with known exposure to the virus.
• Public Education: Information campaigns were launched to educate the public about mpox, its symptoms, and prevention measures.
• International Collaboration: Canada worked with international health organizations to share data and strategies for controlling the outbreak.
