1. What are the signs and symptoms of this virus in people?

The most common symptoms of Zika include:

• Fever
• Rash
• Joint pain
• Conjunctivitis (red eyes)

Other common symptoms include:

• Muscle pain
• Headache

2. How severe is illness associated with Zika?

Most people do not develop symptoms. In the 20% of people who do get symptoms, the illness is usually mild. The biggest concern is the chance of a serious birth defect if a pregnant woman becomes infected.

3. Rash Type and Distribution

At this point in time, the type of rash commonly seen with Zika is still being defined. While the maculopapular rash is reported most often, pruritic rashes have been described as well. Additionally, rash on the trunk and face have been described, but we cannot rule out the possibility rash will distribute differently. CDC would like providers to document all rash information so we can learn more about this symptom.
