Zika virus is transmitted to humans by infected mosquitoes. It causes mild fever and rash. Other symptoms include muscle pain, joint pain, headache, pain behind the eyes and conjunctivitis.
Zika virus disease is usually mild, with symptoms lasting only a few days.
The disease has similar clinical signs to dengue, and may be misdiagnosed in areas where dengue is common.
There is no cure for Zika virus disease. Treatment is focused on relieving the symptoms.
Prevention and control relies on reducing the breeding of Aedes mosquitoes and minimizing contact between mosquito vectors and people by using barriers (such as repellents, insect screens), reducing water-filled habitats supporting mosquito larvae in and close to dwellings, and reducing the adult mosquito populations around at-risk communities.
