How Zika Virus is Spread
The majority of Zika virus cases are caused by the bite of infected Aedes mosquitoes. However, there is also evidence that mother-to-child transmission may occur. There have also been reports of Zika virus being spread through infected blood and sexual intercourse.
Symptoms and Treatment of Zika Virus
Symptoms of Zika virus include low-grade fever, headache, pink eye, rash, joint/muscle pain, and lack of energy. The incubation period of Zika virus ranges from three to 12 days. The disease symptoms are usually mild and last for two to seven days. Approximately one in four people infected with Zika virus are believed to develop symptoms.
Most people fully recover without severe complications, and hospitalization rates are low. Zika virus infection may go unrecognized or be misdiagnosed as dengue, chikungunya or other viral infections causing fever and rash.
Currently, there is no vaccine for Zika virus, although the development of one is underway.
Countries Affected by Zika Virus
First reported in 1947 in the Zika forest of Uganda, outbreaks of the Zika virus have since been reported in Africa, Asia and the Oceanic Pacific Region. In 2015 and 2016, Zika virus was reported for the first time in the Americas, including Brazil and parts of Central America, South America, the Caribbean and Mexico.

Risk of Zika Virus in Canada
The overall risk of Zika virus infection to Canadians (while in Canada) is relatively low. The two main types of mosquitoes (Aedes aegypti and Aedes albopictus) known to transmit Zika virus are not found in Canada because of its cool climate. There have been travel-related cases of Zika virus reported in Canada in returned travellers from countries where the virus is known to circulate.
Advice for Travelers
If you plan to travel to countries where Zika virus is circulating, reduce your risk of getting sick by protecting yourself from mosquito bites. Use insect repellent containing DEET and wear protective clothing.

If you are pregnant (or considering becoming pregnant) and are going to travel to a country with Zika virus, discuss your travel plans with your health care provider to assess the risk.
For additional information, please refer to the Government of Canada’s Travel Health Notice for Zika Virus.
If you develop symptoms similar to Zika virus infection when you are traveling, or after you return, see a health care provider and tell them where you have been traveling or living.
