Key Facts

  • Zika virus disease is caused by a virus transmitted by Aedes mosquitoes.
  • People with Zika virus disease usually have a mild fever, skin rash (exanthema) and conjunctivitis. These symptoms normally last for 2-7 days.
  • There is no specific treatment or vaccine currently available.
  • The best form of prevention is protection against mosquito bites.
  • The virus is known to circulate in Africa, the Americas, Asia and the Pacific.

The same mosquito also transmits 3 other vector-borne diseases -- dengue, chikungunya and yellow fever – across tropical and subtropical regions around the world.

The most common symptoms of Zika virus are headache, muscle and joint pain, mild fever, rash, and inflammation of the underside of the eyelid.

To lower the risk of being infected with Zika virus: use insect repellent; cover as much of the body as possible with long, light-colored clothing; empty, clean or cover containers that can hold water to remove places mosquitoes can breed; and sleep under mosquito nets.
