US scientists have urged the World Health Organisation to take urgent action over the Zika virus, which they say has "explosive pandemic potential".
Writing in a US medical journal, they called on the WHO to heed lessons from the Ebola outbreak and convene an emergency committee of disease experts.
They said a vaccine might be ready for testing in two years but it could be a decade before it is publicly available.
Zika, linked to shrunken brains in children, has caused panic in Brazil.
Thousands of people have been infected there and it has spread to some 20 countries.
Some of the advice being given in affected countries is: women shouldn't become pregnant for two years given the risk.
Pregnant women warned not to travel infected regions.
The Zika virus was first discovered in monkeys in the Zika forest in Uganda in 1947 and the first human case was in Nigeria in 1954. Then cases in Pakistan, Malaysia and Indonesia in 1977/78, then Micronesia in 2007, French Polynesia in 2013 and now in South America since 2015.
It is believed some of the cases of Zika virus have been sexually transmitted.
Not great for pregnant women, or people in general or for Brazil and the Olympics with this virus out of control at the moment, with pandemic potential.
Will this turn into another Ebola disaster but without the death toll?
