What are the symptoms of Zika virus?

The most common symptoms of Zika virus are low-grade fever, usually 99 to 100 or 101; some muscle aches; some joint pain and conjunctivitis or red eye. The disease is very self-limiting. People will have symptoms for three to seven days. They will take a little Tylenol, stay well hydrated and get better just like that. In most cases, people would rarely miss a day or two of school or work. It’s really the infants doctors are worrying about–women carrying babies–because Zika virus infection during pregnancy can cause a serious birth defect called microcephaly, as well as other severe fetal brain defects.

Zika symptoms include:

  • fever
  • pink eye
  • skin rash
  • joint pain

These symptoms can be confused with those of other diseases. Lab tests can tell if you have the Zika virus.

The most devastating problem related to Zika is when a woman gets the infection when pregnant. Babies born to moms with Zika may have brain damage and microcephaly, which is a small head.

Symptoms of the Zika virus include:

  • Body aches
  • Conjunctivitis (pink eye)
  • Fever
  • Joint pain
  • Rash
  • Muscle pain and headache (less common)

Eighty percent of people with Zika virus have no symptoms, and the remainder usually have mild symptoms of a fever, rash, and sometimes joint aches or eye irritation. Symptoms generally last a week. Headache and muscle aches are sometimes seen.

Zika virus usually has no symptoms at all. Only about 20 percent of people who become infected will have symptoms, and those are usually mild. People may have a fever, skin rash, red eyes, joint pain or sometimes headaches. The symptoms typically start three to twelve days after the mosquito bite, and last between two and seven days. Rarely, the virus can cause complications in people with existing conditions, which can lead to hospitalization or death.

Most people who are infected with the Zika virus don't get sick and have no signs or symptoms. If you do get sick with Zika, it's usually a mild illness, and you may not even know you're infected. If you do have signs or symptoms, they usually begin 2 to 7 days after you’ve been exposed to the virus. You can be sick with Zika for several days to a week. Signs and symptoms of Zika include:

  • Headache
  • Fever (You may or may not have a fever if you have Zika.)
  • Joint or muscle pain
  • Pink eye (also called conjunctivitis) or pain behind the eyes
  • Rash
  • Throwing up
