Zika virus has been a widely discussed health concern recently. Zika virus is spread by Aedesmosquitos in areas with these mosquito types. If someone contracts Zika, there typically are mild to no symptoms shown. Should someone develop symptoms, they would likely be rash, joint pain, fever, red eyes, headache, or muscle pain. Zika will likely clear itself out of the body within one week. At that point, the person would then have immunity to future infections.
