The Public Health Agency of Canada has recently confirmed travel-related cases of Zika virus from Central and South America. Since Zika virus is spread through mosquito bites, travellers to Central and South America, particularly pregnant women or those considering becoming pregnant, should protect themselves from mosquito bites. Mosquitoes known to transmit the virus to humans are not present in Canada.
The risk of Zika virus to non-travelling residents of Saskatchewan is considered low.
Zika virus has been reported in Africa and parts of Asia since the 1950s, and in the southwestern Pacific Ocean in 2007. In 2015, Zika virus emerged in South America with widespread outbreaks reported in Brazil and Colombia.
In November 2015, a Brazilian investigation indicated an average twenty-fold increase in the incidence of microcephaly (abnormally small head) among newborns born in areas where Zika virus was known to be in circulation. Although there is mounting evidence to warrant concern, the investigation is ongoing to confirm whether Zika virus may be the cause of these microcephaly cases.
Only one in four people infected with Zika virus are believed to develop symptoms. These include: low-grade fever, joint pain, red eyes, rash and generalized symptoms such as muscle pain, physical weakness, lack of energy and headaches. The incubation period of Zika virus ranges from 3 to 12 days. The disease symptoms are usually mild and last for 2 to 7 days. Most people recover fully 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.
