Zika virus facts:

  • The Zika virus is thought to be most dangerous to pregnant women. It has been linked to birth defects, such as microcephaly, which causes babies to be born with abnormally small heads.
  • The majority of cases are thought to be caused by bites from infected Aedes mosquitoes, which are most active during the day.


  • These may include a low-grade fever; rash; joint, muscle or eye problems (either conjunctivitis or red eye) and a headache. They are usually mild and last two to seven days, but often they don’t appear at all.

Reducing risk:

  • Avoid bites from Aedes mosquitoes by using insect repellent containing N, N-Diethyl-meta-toluamide (DEET) on exposed skin and wearing loose clothing to cover arms and legs.
  • DEET is safe to use during pregnancy and should be applied to skin before sunscreen.

Diagnosis and treatment:

  • A blood test can diagnose the virus.
  • Drinking plenty of water and taking paracetamol may offer some relief from symptoms, but there is no treatment.
  • Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) such as Ibuprofen, are not recommended, as they could trigger excessive bleeding.
  • Anyone displaying symptoms for more than a week should seek medical advice.

History of the virus

The virus was isolated for the first time in 1947, in the Zika forest in Uganda. Since then, it has remained mainly in Africa, with small and sporadic outbreaks in Asia. In 2007, a major epidemic was reported on the island of Yap (Micronesia), where nearly 75% of the population was infected.
