Zika Virus – What you need to know

What is Zika virus?

Zika virus infection is a mosquito-borne disease that is it is spread by mosquitoes infected with the virus. In 2015, there was an outbreak reported in Brazil and Columbia.  Zika virus infection may or may not cause symptoms. If symptoms develop, they are mild and last 2-7 days. The main symptoms include:

  • fever

Recently, there have been some cases in Brazil which suggest Zika virus infection in pregnant women can cause birth defects, like incomplete brain development and abnormally small heads (or microcephaly).
