Zika virus disease

Zika is a flavivirus that is mainly transmitted by mosquitoes. Since early 2015, a Zika virus outbreak has been spreading in the Americas. The most common symptom is a rash – with or without fever – that lasts two to seven days. Patients may also get conjunctivitis (also known as pink eye), as well as muscle and joint pain. Zika virus disease is normally a mild disease and 80 % of infected people do not develop symptoms at all.
