The United States 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, reports the BBC.

‘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.’

‘The Brazilian President, Dilma Roussef, has urged Latin America to unite in combating the virus.

She told a summit in Ecuador that sharing knowledge about the disease was the only way that it would be beaten. A meeting of regional health ministers has been called for next week.’

‘Writing in the Journal of the American Medical Association, Daniel R Lucey and Lawrence O Gostin say the WHO’s failure to act early in the recent Ebola crisis probably cost thousands of lives.’

‘They warn that a similar catastrophe could unfold if swift action is not taken over the Zika virus.’

‘There is no cure for the virus and the hunt is on for a vaccine, led by scientists at the University of Texas Medical Branch.’

‘The researchers have visited Brazil to carry out research and collect samples and are now analysing them in a suite of high-security laboratories in Galveston, Texas.’
