The Zika Virus is likely to spread across nearly all of the Americas, the World Health Organization (WHO) has warned.
The infection which causes symptoms including mild fever, conjunctivitis and headache has already been found in 21 countries in the Caribbean, North and South America.
It has been linked to thousands of babies being born with underdeveloped brains and some countries have advised women not to get pregnant.
In a statement, the Pan American health Organization (PAHO) the regional office of the WHO said: “PAHO anticipates the Zika Virus will continue to spread and will likely reach all countries and territories of the region where the Aedes mosquitoes are found.”
No treatment or vaccine is available, and the lack of immunity in the Americas is thought to be helping the infection to spread rapidly.
