Most people do not experience symptoms, but some Zika victims report nausea, abdominal pain, and occasionally diarrhea. These symptoms appear 2-12 weeks after a bite. Truthfully, they tend to go away within a week. However, extreme symptoms can last weeks or months. Zika does not usually kill those who are afflicted with the virus, but it can harm the unborn fetus of a pregnant woman who contracts the virus.
