An international map and data are available.
Globally, efforts have focused on taking measures to contain the outbreak and prevent further spread.
Travel advice and advisories are the Government of Canada's official source of destination-specific travel information. They give you important advice to help you to make informed decisions and to travel safely while you're abroad.
Risk to Canadians
Some people are at higher risk of more severe disease or outcomes from COVID-19 infection than others. However, there are a number of vaccines and treatments available.
The risk of getting COVID-19 varies between and within communities. Some settings and activities are also associated with higher risk of COVID-19 transmission.
We continue to reassess the public health risk based on the best available evidence as the situation evolves.

How Canada is monitoring COVID-19
The Public Health Agency of Canada is working with provinces, territories and international partners, including the World Health Organization, to actively monitor the situation. Global efforts are focused on containment of the outbreak and the prevention of further spread.
Canada's Chief Public Health Officer of Canada is in close contact with provincial and territorial Chief Medical Officers of Health to ensure that any cases of COVID-19 occurring in Canada continue to be rapidly identified and managed in order to protect the health of Canadians.
Canada's National Microbiology Laboratory is performing diagnostic testing for the virus that causes COVID-19. The laboratory is working in close collaboration with provincial and territorial public health laboratories, which are now able to test for COVID-19.

Genetic variations of viruses, such as the one that causes COVID-19, are common and expected.
SARS-CoV-2, the virus that causes COVID-19, will naturally develop mutations, which are changes to the genetic material in the virus over time.
When there have been several significant mutations to the virus then it's called a variant. A variant is of concern when it affects:
- disease spread
- disease severity (for example, whether you have mild symptoms or require hospital care)
- tests used to detect the virus
- protection from previous infection, vaccines or treatments
Monitoring the variants
Monitoring for genetic changes in the virus allows us to better understand the potential impact of the mutations.
The Public Health Agency of Canada works with the provinces and territories, and other partners to monitor and identify variants of concern in Canada.
Currently, Omicron and its sub-lineages are the primary variants of COVID-19 circulating in Canada.
Evidence demonstrates that Omicron is more transmissible than previous variants of concern. Vaccination is one of the most effective ways to protect our families, communities and ourselves against COVID-19. A booster dose following a primary series of mRNA vaccines offers better protection against Omicron infection and severe disease than the primary series alone.
Previous variants of concern in Canada are as follows:
These variants are no longer considered variants of concern. They aren't spreading widely and no longer pose a significant risk to people in Canada.
About the variants
Variants of concern include mutations that seem to make the virus more infectious, allowing it to spread more easily. They may also affect the severity of the disease.
At this time, there's evidence that some variants may have an impact on certain drugs and vaccines. However, more research is needed to confirm these findings.
The variants don't currently affect the performance of COVID-19 authorized tests, including rapid antigen tests.
Given the limited data on new variants as they emerge, research is needed to confirm early findings on their significance. The Canadian and global medical, public health and research communities actively evaluate these variants and other significant mutations.
