The Zika virus is a mosquito-borne infection which was first identified in Africa in 1947. It has spread significantly across the world since the first reported case in Brazil in 2015.
For most people it is a very mild infection and isn’t harmful.
The majority of those infected with Zika have no symptoms and won’t even know they’ve got the virus. In others it can cause a mild illness with symptoms including a rash, conjunctivitis, fever and headaches. These will generally last for a few days to a week. However, the virus can cause microcephaly and other congenital abnormalities in babies born to mothers infected with the virus.
People very rarely die from Zika and infected people who have died have had underlying conditions.
