Zika is an infection spread mainly by mosquitoes found in parts of the Americas, the Caribbean, Africa and Asia. It can be harmful to pregnant women.
A Zika virus infection often has no symptoms. Some people get symptoms like a rash, high temperature, headache or muscle aches for a few days.
Zika virus is usually caught by being bitten by an infected mosquito. There's also a very small risk of it being passed on through sex.
You can reduce your risk of getting Zika virus by avoiding mosquito bites. For example, use insect repellent and sleep under a mosquito net.
There's no treatment for a Zika virus infection. It usually gets better in about a week. Staying hydrated and taking painkillers can ease symptoms.
