Symptoms of Zika

Only 1 in 4 people infected with the Zika virus are believed to develop symptoms.

The main symptoms of Zika include:

  • red eyes
  • general symptoms, such as:
    • weakness
    • headaches
    • lack of energy
  • short-term muscle or joint pain
    • possible joint swelling, mainly in the smaller joints of the hands and feet
  • low-grade fever (37.8 to 38.5°C)
  • a flat, red rash covered with small bumps on the skin

It usually takes between 3 to 14 days for symptoms to appear after infection. The symptoms are usually mild and last for 2 to 7 days.

Symptoms of Zika can be similar to other travel-related viral diseases, such as dengue and chikungunya. However, Zika symptoms are typically milder.

What to do if you become ill

See a health care provider if:

  • you have or develop symptoms consistent with Zika
  • you or your sexual partner have travelled to a Zika-affected place

This is especially important for:

  • pregnant women
  • people who have weakened immune systems (a reduced ability to fight disease)

Tell your health care provider:

  • where you've been travelling or living
  • if you have had unprotected sexual contact with someone who could be infected with the Zika virus
