The word "zika" is derived from the Zika forest in Uganda, where the virus was first isolated by scientists from a sentinel rhesus monkey.
Transmitted to humans via mosquitoes, the Aedes mosquito - which also spreads dengue and chikungunya - is the only known carrier of the virus.
2. WHAT ARE THE SYMPTOMS TO LOOK OUT FOR?
The symptoms associated with the virus are usually quite mild, and only about one in five people infected actually fall ill.
Common signs to look out for include a slight fever, rash, conjuctivitis, headache as well as joint and muscle pain.
The incubation period is not known, but is likely to range between a few days to a week. During the first week of infection, the virus can be found in the blood and passed from an infected person to a mosquito through mosquito bites.
Hospitalisation due to the virus is not common, while deaths are rare.
