The World Health Organization says the Zika virus has spread to 32 countries and territories. It warns people to cover up to avoid infection with the mosquito-borne virus.
The infections affect mostly the Caribbean and Central and South America, including Brazil and Mexico. The disease is also confirmed in Fiji, Samoa and two other Pacific island nations.
Cabo Verde in Africa and the Maldives in the Indian Ocean have also confirmed infections.
WHO spokesperson Gregory Hartl said the key to preventing the spread of the virus is to minimize exposure to mosquitoes.
The WHO advises people to use mosquito repellents and wear clothing that covers the skin. It says people should close doors and sleep under mosquito nets.
While yet to be confirmed by the WHO, health authorities in the United States and Thailand have also reported Zika infections.
