What is Zika Virus?

  • Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes.
  • People with Zika virus disease can have symptoms including mild fever, skin rash, conjunctivitis, muscle and joint pain, malaise or headache. These symptoms normally last for two to seven days.
  • There is scientific consensus that Zika virus is a cause of microcephaly and Guillain-Barré syndrome. Links to other neurological complications are also being investigated.
  • There are no reports of mosquitoes spreading Zika virus in Canada. There’s an ongoing, low level of risk to Canadians travelling to countries or areas in the United States with reported mosquito-borne Zika virus.

The understanding of Zika virus transmission, risks and complications is evolving.
