Zika is usually mild with symptoms lasting for several days to a week. People usually don't get sick enough to go to the hospital, and they very rarely die of Zika. For this reason, many people might not realize they have been infected.
How soon you should be tested
Zika virus usually remains in the blood of an infected person for about a week. See your doctor or other healthcare provider if you develop symptoms and you have recently traveled to an area with Zika. Your doctor or other healthcare provider may order blood tests to look for Zika or other similar viruses like dengue or chikungunya. Once a person has been infected, he or she is likely to be protected from future infections.
When to see a doctor or healthcare provider
See your doctor or other healthcare provider if you have the symptoms described above and have visited an area with Zika, this is especially important if you are pregnant. Be sure to tell your doctor or other healthcare provider where you traveled.
