Zika virus infection is a mosquito-borne viral disease caused by Zika virus, which is characterized by mild fever, rash (mostly maculopapular rash), headache, joint pain, muscle pain, weakness and non-suppurative conjunctivitis. These symptoms appear from 3 days to 12 days after mosquito bites. A quarter of patients may have no symptoms, but the mild symptoms that infected people usually have may last for 2 to 7 days. Its clinical manifestations are often similar to dengue fever, and it is also a mosquito-borne disease. Zika virus can spread through the territory where Aedes mosquitoes are located. When traveling to areas where Zika virus is prevalent, you should take personal protective measures to reduce mosquito bites.
