Zika is a type of virus that is spread by mosquitoes. The mosquitoes that carry Zika are most active during the day but can bite at night.
You're more likely to get the virus if you travel to parts of the world where it's more common. This includes parts of South America, Central America, Mexico, the Caribbean, and the Pacific Islands.
Most people infected with Zika don't have any symptoms. When symptoms are present, they include fever, rash, painful joints, and red eyes. But it can be more serious for women who are pregnant because it can cause birth defects.
Doctors are quickly learning more about what happens when people are infected with Zika virus. The Public Health Agency of Canada (PHAC), the U.S. Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO) have the most current information about Zika virus. If you plan to travel, you can learn about your risk in the area you're travelling to. Contact:
Zika is most often spread through a bite from an infected mosquito. Zika virus is usually spread by two species of mosquitoes that are found in warm, tropical climates. It can be spread by someone who has the Zika virus through sexual contact, even if the infected person does not have symptoms.
Travellers who have Zika can spread it if they are bitten by a certain type of mosquito and then these mosquitoes bite other people. These mosquitoes are not found in Canada at this time.
A pregnant woman who gets infected with Zika can pass it to her unborn baby.
Most people infected with Zika don't have any symptoms. Symptoms are usually mild. They most often start within a week after the bite. The main symptoms may include:
Some people also have a headache and muscle pain.
There is no specific treatment for Zika virus. Symptoms usually go away on their own after about a week.
Treating your symptoms may help you feel better.
Experts believe that babies born to women who have the virus are at risk for birth defects, including microcephaly (say "my-kroh-SEF-uh-lee"). Microcephaly means that the baby's head is smaller than normal. It causes problems in how the baby's brain develops.
The Public Health Agency of Canada (PHAC) recommends that pregnant women wait until after they give birth before they travel to areas where there are Zika outbreaks.
Zika can be spread through sexual contact even if the person does not have symptoms. If your male partner has been to an area where there is a Zika outbreak, experts recommend you delay having sex until the baby is born or always use condoms correctly every time you have vaginal, anal, and oral sex.
If you are pregnant and have travelled to an area with an outbreak of Zika, talk to your doctor about getting tested for the Zika virus.
Women who are thinking about becoming pregnant and their male partners should talk to their doctor about the risk of travelling to areas where there are Zika outbreaks. Experts recommend that you delay pregnancy if you or your male partner has been to an area with ongoing Zika transmission.
After returning from an area with risk of Zika:
There is no vaccine to prevent Zika. But you can protect yourself from mosquito bites, especially when you travel.
If you do get infected with Zika, take steps to prevent the spread of the virus. Men should always use condoms correctly or not have sex for at least 3 months after symptoms begin. Women should always use condoms correctly or not have sex for at least 2 months after symptoms begin. This will help prevent the virus from spreading to other people.
