Zika virus

The Zika virus is a viral infection (ZIKV) that mainly occurs in (sub)tropical areas. Travellers to these regions are at risk of contracting the Zika virus, which is transmitted by Aedes mosquitoes. These mosquitoes also spread diseases like dengue and chikungunya. Zika fever is often mild, but an infection during pregnancy can have serious consequences for the unborn child. Good protection against mosquito bites is essential when travelling to areas where the Zika virus is present. An infection with the Zika virus is often mild. Symptoms usually appear within three to twelve days after a mosquito bite. The main complaints are:

Where does the Zika virus occur?

The Zika virus mainly occurs in parts of Africa, Asia, Central and South America, and countries in and around the Indian Ocean. These mosquitoes are also found in urban areas and are mainly active during the day (not at night like the malaria mosquito). The situation can change quickly per region. Check the information for your destination.

What are the symptoms?

• Acute fever
• Conjunctivitis (eye inflammation)
• Muscle and joint pain (especially in hands and feet)
• Skin rash
• Less common: headache, loss of appetite, vomiting, diarrhoea, and abdominal pain

Sometimes the infection occurs without symptoms, making the virus treacherous for pregnant women. An infection during pregnancy can lead to abnormalities in the baby, such as microcephaly. Travelling to areas with a current outbreak of the virus is therefore not recommended for pregnant women. Areas without a current outbreak can be visited, provided preventive advice such as strict mosquito-repellent measures are followed.

How do you prevent Zika virus?

There is no vaccine against the Zika virus, so protection against mosquito bites is the main way to prevent infection. Therefore, apply good mosquito-repellent measures.

During an outbreak, avoid unprotected sexual contact with someone who has recently been in an outbreak area, especially if you are pregnant or trying to become pregnant. Also read our tips for pregnant and travelling.
