  Zika virus disease is primarily transmitted by the bite of an infected mosquito from the Aedes genus, mainly Aedes aegypti, in tropical and subtropical regions. The incubation period (the time from exposure to symptoms) of Zika virus disease is estimated to be 3 to 14 days. The majority of people infected with Zika virus do not develop symptoms. Symptoms are generally mild including fever, rash, conjunctivitis, muscle and joint pain, malaise, and headache, and usually last for 2 to 7 days. […] Zika virus infection during pregnancy is a cause of microcephaly and other congenital abnormalities in the developing fetus and newborn. Zika infection in pregnancy also results in pregnancy complications such as fetal loss, stillbirth, and preterm birth. […] Zika virus infection is also a trigger of Guillain-Barr syndrome, neuropathy and myelitis, particularly in adults and older children.

  Many people infected with Zika virus will not have symptoms or will only have mild symptoms. […] The most common symptoms of Zika virus disease (Zika) are: Fever, Rash, Headache, Joint pain, Conjunctivitis (red eyes), Muscle pain. […] Zika symptoms usually last for several days to a week. People usually do not get sick enough to go to the hospital. For this reason, many people might not realize they have been infected. […] People very rarely die of Zika. […] Zika infection during pregnancy can cause serious birth defects and is associated with other pregnancy problems, including fetal loss, stillbirth and preterm birth. […] Rarely, Zika infection may cause Guillain-Barr syndrome (GBS). GBS is a sickness in which a persons own immune system damages their nerve cells causing muscle weakness and sometimes, paralysis. These symptoms can last a few weeks or several months. Most people fully recover from GBS, though some people have permanent damage. Very few people die from GBS caused by Zika infection. […] In rare cases, Zika may cause severe disease affecting the brain, causing swelling of the brain (encephalitis), tissues around the brain (meningitis) or spinal cord (myelitis). Zika may also cause a blood disorder which can result in bleeding, bruising, or slow blood clotting.
