Has Zika virus been detected in Canada?

As of February 9, 2017, there are 473 travel-related cases and 3 sexually transmitted cases, including 27 pregnant women reported in Canada.Footnote * There's ongoing low risk to Canadians travelling to countries or areas in the U.S. with reported mosquito-borne transmission of Zika virus.

The data will be updated monthly. The next update will be made on Thursday, March 9, 2017.

The number of reported Zika-related pregnancies may not reflect all pregnancies and pregnancy outcomes among Zika-positive women in Canada.

The data for fetal and newborn outcomes include observations made during:

  • pregnancy
  • pregnancy losses, including miscarriages, stillbirths and terminations
  • births 

Zika-related congenital anomalies could present as:

  • neurological manifestations of varying degrees, ranging from mild to severe, and/or
  • a congenital syndrome associated with Zika virus infection, including, but not limited to, microcephaly

How many cases are there of Zika virus around the world?

The virus was first identified in humans in the 1950s. From 1951 through 1981, evidence of human Zika virus infection was reported from African countries and in parts of Asia.

In 2007, the first major outbreak of Zika virus occurred in Micronesia (Yap island) in the southwestern Pacific Ocean. This was the first time that Zika virus was detected outside of Africa and Asia.

Between 2013 and 2015, several significant outbreaks were noted on islands and archipelagos from the Pacific region. This included a large outbreak in French Polynesia.
In early 2015, Zika virus emerged in South America with widespread outbreaks reported in Brazil and Colombia.

The World Health Organization monitors Zika case reports from around the world. To date, a number of countries, territories and areas have reported cases of microcephaly and/or central nervous system malformation potentially associated with Zika virus infection. Monitoring of pregnant women in other countries experiencing Zika virus outbreaks is ongoing.

How does Canada monitor Zika virus?

The National Microbiology Laboratory is able to detect the virus and offers testing support to provinces and territories.

As part of their West Nile virus surveillance programs, several provinces and territories conduct mosquito surveillance activities.

Planning is underway to enhance mosquito surveillance to detect an introduction of new mosquito species into Canada. This would include those species responsible for Zika virus transmission.
