Zika Information and Resources


Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito (Aedes aegypti and Aedes albopictus). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms. However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects. There has not been any local transmission of Zika in Louisiana to date.

  • Zika is linked to birth defects. Zika infection during pregnancy can cause a serious birth defect called microcephaly that is a sign of incomplete brain development. Doctors have also found other problems in pregnancies and among fetuses and infants infected with Zika virus before birth. If you are pregnant and have a partner who lives in or has traveled to an area with Zika, do not have sex, or use condoms the right way, every time, during your pregnancy. Pregnant women should not travel to areas with Zika. Click here for more information about Zika and pregnancy.
