Signs and symptoms of Zika virus are vague and can last for up to a week. Diagnosis of the virus is typically confirmed with a blood test.
Symptoms of Zika virus include:
Fever
Rash
Joint pain
Conjunctivitis (red eyes)
Muscle pain
Headache
Pain behind the eyes
Vomiting.
Microcephaly
Data suggest that newborns of mothers who had a Zika virus infection during the first trimester of pregnancy are at an increased risk for microcephaly. Since December 2015, it has been suspected (but not proven) that a transplacental infection of the fetus may lead to microcephaly and brain damage.

- Cases of Zika virus infection that result in hospitalization are uncommon
- A link between maternal Zika infection and infant microcephaly is currently being investigated
- As yet, there is not enough evidence to fully characterize the link between the two conditions
- There is currently no evidence of Zika virus transmission via breastfeeding
- At present, there is no treatment for the virus
- Avoiding mosquito bites is a key aspect of Zika virus prevention.
